ELR HAND LOADING TIPS No 5

[@mjsmith1223]

This type of thing is where KZbin really shines: I can soak up the wisdom of someone on the other side of the world. Very well done.

[@markandsamafterwork]

Thanks Man, Cheers

Except KZbin/Google/FaceBook/Instagram/Twitter doesn't want you thinking about guns

[@gunslinger7647]

Finaly, the truth of hand loading. There are no gives, be flexible and change with as conditions require. I was taught these things in the 70 s, and things haven't changed in this respect. Neater loading tools. Same theory. Love your videos.

[@markandsamafterwork]

Thanks Man, glad you liked, Cheers

[@ashleynicely1046]

Excellent presentation. Obviously, you have a fine mind for organization, detail, and data assimilation, Mark. It's truly a pleasure to listen to your explanations and reasoning, and what it means to me is a starting point for exploration in any direction I might choose to go in. Great videos. I would like to see you doing more paper grouping at mid ranges like 200-400 yards, especially in the 6mm and smaller calibers. Thank you for your efforts, I hope it pays off for you. It is disappointing to see one million plus views on videos that blow things up and destroy things with guns instead of the pursuit of excellence like you and Sam's videos do so well. Maybe the world will come to its senses if we just keep trying to infuse sense into the picture.

[@markandsamafterwork]

Thanks Ashley, glad you liked, yes I hear you, Cheers and all the best.

Your comments on FL Sizing VS Neck Sizing makes sense and given the accuracy your getting in your rifles. Thanks for sharing your wealth of info on precision shooting. Always Great Stuff in your videos!!!

[@markandsamafterwork]

Hi Tim, glad you enjoy, Cheers and all the best.

[@260nob9]

Gee Mark, that was excellent!! 10 stars from me mate. Of particular interest was your comment as to making your rifle shoot your desired load as opposed to developing a load for your rifle to shoot. I've never thought of this though what you say makes very good sense. I've never seen of heard this from any other though when you think about it its very practical. Thanks for your wisdom.

[@markandsamafterwork]

Thanks Man, yeh works for us, only suited to these heavy/varmint barrel ELR rigs but, cheers ans all the best.

[@slipknnnot]

Great insights. I could never understand the logic behind a ladder test and jumping to conclusions based on 5 data points when you have so many variables affecting your groups

[@markandsamafterwork]

Cheers

[@redrock425]

I like Mark's practical approach. With so many variables the only sensible way is use what you find gives you small groups.

[@dwaynerussell9711]

Nice as always Mark, You should maybe try annealing your brass every two to three rounds, it will help you tremendously on neck tension. Tell Sam she does a great job with her spotting and shooting as well.

[@markandsamafterwork]

Thanks Dwayne, we do anneal on occasion, not really found any gains for the way we run our brass at this stage, Cheers

[@jcarne1015]

Thank you Mark. I haven’t done much shooting or any loading in the past 18 years or so, but your videos are stirring my interest again. I was a fussy loader, much like you, and it paid off in the short range shooting I did then. I bought a piece of property in remote southwest New Mexico 12 years ago that would have allowed me to shoot up to about 1500 yards on my own land, but grandchildren came along, and put a stop to that move. A friend of a friend has property here in Florida with a 1000 yard range, but I haven’t shot it yet. Been too busy beating myself up with fast motorcycles... When I did shoot, it was mostly .223 in a 24” AR platform, .308 in a DPMS LR-308, 6.5x55 in a Kimber modified M96, and 7.5x55 in an unmodified K31. I think it’s about time to start setting up again, and maybe the body will be finished healing by the time I’m ready to shoot again. There was a time when Friday night was reserved for loading ammo, and all day Saturday was for shooting. We just adopted three grandchildren last fall, so I have three to pass along what I can teach them now. I had a Barrett M82 that I bought while I was a dealer, but never shot it...it seemed like an awful waste to shoot at 1-200 yards. I sold it and bought another motorcycle.

I totally agree Mark that consistency is the main goal to strive for!! I aways see the impression ring on my reloads on the ogive of the bullet I have been crimping, but most of my loads are for mid range hunting. But i think that is a goal to try and eliminate the ring!!! Thanks for sharing your process as always I've found some advice from your video!!!

[@pjones510]

I really liked this. This is how I feel I need to reload. Totally agree with Good prep and consistency, (not chasing nodes or ladder testing) Do you ever worry about the overall length of the round? How close to the Lans etc... or Is it just getting the projectile to fit? I have tried the same round with multiple distances from the lans with no change to the results. Thanks again to both of you for your vids!

[@markandsamafterwork]

thanks Man, depends on a few details, type of bullet mainly, some just don't mind, never hurts to test, Cheers

[@ashleynicely1046]

Something that would be really interesting would be a video showing the differences in velocities you get using your reloading methods, shooting through chronographs. I think consistent velocity is likely the most important factor in vertical dispersion of shots over distance, and I would like to see what kind of results you're getting with your obviously careful mechanics of reloading. Watching your videos, I wouldn't hesitate having you rebuild an automobile engine for me, it would no doubt beat all manufacturer's tolerances. Thanks again for your efforts.

[@markandsamafterwork]

Hi Ashley, I rarely use a chronograph, I do all that I do with the reloading and then make sure my rounds group well out where I shoot them (ELR) and as said don't mess with my powder load very much at all. I know that is different too many, but has worked well for me, and always dealing with not enough time in everyday. Cheers and all the best.

[@walt5797]

Thanks Mark, excellent presentation as always. Question!! Do you crimp? If I may add that I am also in the mechanical and engineering field, and agree with you with respect to not liking the idea of non-lubed metal on metal, however , I have mentioned this before and you may like to give it a try. I wash all my new projectiles in hot water and dish soup, rinse them and dry them in the oven. I then tumble them for an hour in a small-ish container with 1/4 tea spoon of hex boron nitride. It is like a white graphite but can withstand very high temperatures. It makes the bullet very slippery and easy to load. It also conditions the barrel and felicitates throat longevity. It makes the bullet so slippery that it reduces MV that can be over come with a slight crimp or higher powder charge. It would be at least worth researching. Here is where I have purchased it from, yeah its expensive but a small amount goes a long way, 50 g will do thousands of bullets. www.ebay.com.au/itm/Boron-Nitride-Powder-Hexagonal-50g/223138891558?hash=item33f41d4726:g:QFAAAOSwsN9XChCF:rk:1:pf:0 Kindest regards Walt.

[@markandsamafterwork]

No I do not crimp, that would be almost the opposite of my loading technique, thanks for the info and the link, Cheers

[@rogueaussie9299]

Mark, another great video! Apologies if I missed it but how many times do you find you can reload good brass?

[@markandsamafterwork]

Depends, 3 to 20....Cheers

[@robinsnodgrass260]

good thoughts, some I do myself....the other thing which was not mentioned was annealing case necks....I would like to see you speak up on that subject as well...I myself only do it when I feel it is necessary...say after 5+ reloads and neck tension has become inconsistant as felt while seating projectiles innthe die, and we certainly dont want split necks from work hardening!

[@markandsamafterwork]

i touch on the subject through some of the videos, but yes as needed, Cheers

[@robinsnodgrass260]

MarkandSam AfterWork I am gathering oarts for an automated annealer...single moter timed belt drive setup...this will provide very consistant reults between all cases, something I feel is important for case prep and uniform bullet release, and also in fireforming wildcats with sharp shouler angles

[@imafraidofclowns740]

Another great video, Thank you. What is your opinion of Graphite as a sizing lube? And also could you see any benefit in slightly enlarging the case flash hole to help powder ignition? Thanks again.

[@markandsamafterwork]

Thanks Man, not sure on graphite, I much prefer a sizing lube like RCBS case lube or something like that, but really haven't tried. As for enlarging, not a great idea from my thoughts, you don't want faster you want consistent, also opening up that hole puts more blast pressure on the primer, so no I would not open up the firing hole.

[@Ridindirtycanam]

Awesome video great information !!!

[@markandsamafterwork]

Cheers

[@danielcrossland6915]

Hey great info. What is your opinion on using a outside mike to measure case head expansion? Multiple sources ie: gunsmiths and bullet makers have instructed me that some primers react differently in different rifles depending on bolt lug wear, chambered reamers, etc. They've claimed measuring right before and right after should not see more than 0.0005" expansion. Stop charge at that point. Thoughts..... Many books have claimed this method which you have instructed and seems like a quick visual but I've seen flattened primers and even cratering from base level charges from book..... So it seems there has to be an exact way without using pressure trace equipment.

[@markandsamafterwork]

Experience will tell you that things are always different, you find what is obvious and work to that, if all working well, leave it alone, if you have issues, diagnose and then work to that, pressure signs are just so you can load to a point where everything works well, Cheers

[@danielcrossland6915]

@@markandsamafterwork that's fair enough. It appears both methods work good to a experienced operator. Probably the same discussion as moa or mils. Take care and thank you for your response. Have you ever conducted pressure trace testing?

[@g.j.7175]

Very informative video. I'm just afraid that lubing the case outside is not a good idea. This puts significantly more stress on the breachclosing mechanism, because the cartridge case when fired lose grip in the chamber.

Mark: I did not know where to post or ask the question so I chose this video since it is somewhat related. I believe I remember you saying during one of your videos that you do not really do much in the way of developing a load for a rifle, but instead you find the "upper end of the safe zone" and then "TUNE" your rifle to that particular load. Maybe you have addressed this somewhere else but could you please explain or make a video on how you accomplish this. Thanks from TEXAS!

[@markandsamafterwork]

Great video Mark and Sam thank you for the info. quick question how often do you anneal your brass? also in your neck sizing die do you use bushings?

[@markandsamafterwork]

Thanks Nowell, well I do very little annealing, I really don't find the need. And depends on the cal, but most I don't use bushings, I have found I get the right tensions with std die sets, Cheers

[@lynndragoman1573]

You develop a load like a hunting load rather than a target load. The Sierra Reloading Manual does hunting loads as you describe.

Hi, I’m curious, cartridges are specified to make a certain peak pressure, however I assume primer deformation is primarily relevant to the primer itself How would, for example, a 45acp cartridge relate to a 338lm in terms of primer deformation (low pressure specifications vs high pressure, 19kpsi vs 60kpsi)

[@markandsamafterwork]

This is just one feature I look for, and yes it is not a comprehensive pressure test. It can differ depending on the primer, but this is only in high power/bottle neck (high pressure) rounds, not something to use in a straight wall case, Cheers

[@lovetoflylovetofly3843]

Been watching your efforts and it got me to wondering just how far you could hit with a 20mm? Not certain if they let you have something that large there at this time.

[@markandsamafterwork]

The 20mm units are not really precision rifles, they are made to shoot large targets, so even though they can shoot with a lot of power, a long way, hitting one of our targets out there, is really not feasible. shots on target at extreme range we have one of the best rifles for that already. Cheers and all the best. FYI bigger is not always better!!

Would like to here your toughs on cleaning and copper fouling equilibrium and if you use this concept? . Friend or faux. Interesting tubes on this from TiborasaurusRex.

[@markandsamafterwork]

Well I clean after every shoot, keep action and bolt super clean inside and out, but over the last few years I have settled on minimal barrel cleaning, really carbon only, works great on all my ELR/Target rifles, on target first or second shot all the time. Will do the cleaning video soon, Cheers

[@260nob9]

Yes this make good sense. I think that copper equilibrium is about minimising cold bore shot dispersion. More hunting type action as opposed to ELR Target.

Hello, I have a 300 Win Mag with a 1/10 twist Shilen 30" long, I've been handloading 210 VLDs with Retumbo at a low charge of 76.5 grains. Seating 0.005" away from lands, using the Federal match primers. Accuracy has been quite good, but I'm wondering if the chronographed velocity I got over 20 rounds at 3110ft/s (standard deviation of 17ft/s) is higher than it should be. Strangely enough, no primers are flat, there's a healthy radius, but some cases have a bit of friction on extraction. I neck size to 0.0015" tension, but I don't have a neck reamer, I think it might be causing the odd sticky case. If you have experience with this kind of load, I'd appreciate your input on whether or not they're going too fast for the powder charge or if there's a safety concern, or what neck reamer you'd recommend. Great video, I always learn a lot from your stuff. Thanks!

[@markandsamafterwork]

Lots of potential reasons, brass quality is one of them, and sounds a bit like your problem, I use Norma brass and do not have a problem, but some batches will be different to others, try some different brass and test. FYI you some times just have to keep testing to find the difference. Cheers

[@Meph648]

I've been using Hornady Match brass, that could be it. I'll see if I can save up my pennies for a batch of Norma brass. Thanks a lot for the suggestion!

[@chadmeyer9500]

Pressures are getting pretty damned high by the time rifle primers start getting flat. And how flat they get depends a lot on how they're seated, the primers themselves and how much they're "preloaded" during seating. As cases age, flash holes erode and get larger so you get more pressure back into the cups. No doubt you're using Magnum primers and the real difference in Magnum primers is the thickness and strength of the cup rather than a huge increase in "fire". That's another reason you can't rely on flat primers to indicate pressure. There's a really simple way to see if your loads are too hot. Back the charges down a little. You can't neck size indefinitely and if you're running hot loads you want to full-length size every 3-4 reloads and annealing the necks is an excellent idea. Brass work-hardens. The harder you hit it with high pressures or long pressure curves the faster it will harden and the harder it will get.

[@chadmeyer9500]

Hornady brass is as good as any and better than most. Hornady is owned, operated and staffed by dedicated gun folks who work there because they want to. Not because that's the job available in a European socialist country where 99% of employees have "job security" whether they want it or not. There are plenty of other things to look at before assuming its the brass "quality" and it makes a hell of a lot more sense to figure out what's going on with less expensive brass than more expensive brass.

[@markandsamafterwork]

Yes I would agree, as said lots of things could be the deal, as I re-read, your MV is quite high for your powder load, once again a few details can cause, but also points to another place, the primer, I do not use magnum primers in my 300, I do use Federal GM LR primers, I found these to give better consistency and nicer to shoot. But as said I also found best results with the Norma brass. While not suggesting better quality than any particular brass, the capacity and general consistency helped me. But I am sure there are many far more experienced loaders/shooters that will differ from my suggestions, this is what I found with my 300. Cheers

Great information Mark! Hey, have you ever heard of cryogenically treating a barrel? They say it will releive any residual stresses left in the barrel after manufacturing and also give it a more martensitic structure so it be harder and will increase life. I have not done it yet but some friends have done it with some rifles that they can't get to group right and they were amazed at the results. Check it out. www.300below.com/ I would be interested in your thoughts on this. Jim

[@markandsamafterwork]

Thanks Jim, yes I have heard of cryogenic treatments in all forms of engineering, in general there is not a lot of really data to support what seems a logical theory, but yes in some places there seems to be real gains. I think that with the right minor stress in metal that it can help, but as a rule if a barrel is built in the correct manner with good even steel then it will not make any improvements. A lot of the time it is everything else that happens while the treatment is taking place that makes the difference but, I am not one to judge, I have not tried, Cheers
