[@jimbrock8310]

I have swiped pistol and rifle primers for 40 years mag or not. I have never had an issue as long as I don't load to max! The hand books they have out today are all lawyered up. my old books are dead on for max performance! The only primers I have ever blown out was 357 mag and 22-250 Rem. That was only because I was loading at max. Max load is not your most accurate anyway. Start a couple grains below and work up or down until you find what your gun likes! 2-3 hundred fps is not going to make much difference in shocking power! Accuracy and shot placement are what it is all about! There have probably been more game animals harvested with a 22 long rifle or a 30-30 than any other rifles! They will all do the job if you hit your target! One shot one kill!

[@torreyintahoe]

I have thousands of large pistol primers and don't use them as I only load 9mm and 38 super in pistol, so I was wondering about using them for rifle. Most of the guys on the forums say not to do it though.

[@jmfa57]

@@torreyintahoe I highly recommend that you NOT do that. I inadvertently mixed large pistol primers into my 7x57 reloads, which were thankfully rather mild. I loaded up 20 or 30 before discovering my mistake. I chose to take them to the range anyway. I had a couple where the primer was punctured. Thank goodness I didn't get any blowback into my face. The primer cups are nearly always thin on pistol primers, a bit thicker on magnum pistol primers, and thicker yet for rifle primers. So long as your pistol has a strong enough firing pin spring to shoot your rifle primers, the gun will go BANG, but I think it's really risky using any pistol primer in a rifle cartridge. Good luck and be safe!

[@jimwhite9483]

Hope you're proud of yourself. I guess getting the sins of your past off your chest gives you comfort in your last days. You're possibly one of the reasons we have a shortage in these days. Just how many primers have you swiped over your 40+ years of pocketing them?

[@richardgainey8790]

Quite a bit of research has been done lately on the effect of humidity with regard to powder burn rates. Possibly the new lot of RL26 had less H2O content and therefore more volume per 49 grains with a faster burn. Double whammy, especially when nearing max case capacity. Thanks for the great content!

[@archangel20031]

Rifle primers tend to be made out of thicker material because rifles tend to fire at higher pressures. I actually have a brick of Sellier and Bellot small universal primers where it's printed on the box that they can be used for pistol or rifle.

[@G5Hohn]

It's amazing how much case capacity and bullet selection can matter along with powder lots. I hit pressure with RL26 and SRP Peterson brass rather easily around 46gr with 140ELDs. Nearly 2900fps with a 140 is itself a pressure sign in 6.5. Pretty sure all three kegs I have are same lot (*flex*), but I haven't confirmed. Peterson seems to be pretty heavy brass (more like Lapua) and a bit less case capacity as a result. Not sure if their LRP brass is the same. I use 450s with SRP brass.

Very good advice here. I've come to accept, that for me, 'good enough is going to have to do'. With limited availability of components I can load up to 'good enough' rather than fine tuning to someting better. I have a good supply of components on hand and I'm not going to use them up chasing a super sweet spot. Sometimes, 1/2 MOA or 3/4 MOA or even MOA is going to have to do. To keep shooting at some good volume, I just a bought a Christensen Arms .22LR and I have a good supply of ammo for it. It's just going to have to do.

Those kind of speeds seem quite excessive to begin with so I would imagine they were on the edge to begin with.

As someone else mentioned I too have been loading for over 40 years. In the old days all small primers were the same and the boxes were labeled " small pistol/rifle" primers. Large primers are a bit different as large rifle primers are a bit harder and ever so slightly taller However I've used em in for example. 45 ACP so long as it's a strong hammer spring weapon. Now onto magnums The magnum primers I've used burn hotter but DO NOT create more pressure Let me repeat THEY DO NOT create more pressure. I've swapped primers back n forth for almost 50 years now I even reload primers!!! The only issue I ever had was using large rifle primers with striker fired weapons. They didnt have the strength to crush occasionally so I'd get an occasional misfire. Like you I run the blue press as well as other progressives an single stage. I've loaded many 1000s of rounds per week for many MANY years as I've said

While rifle primers may be able to withstand pistol case pressures, pistol primers may not be able to withstand rifle case pressures. Primers are made for certain case pressures. Some have used pistol primers in rifle cases without failures but they did so with low charges and therefore lower pressures. Bottom line is just follow manufacture load data to stay safe. If you use other primers in other cases then know the risks and dangers of increased case pressures.

Hi BT, Depending on how consistent things are lot to lot , yes small changes may be needed. There are many factors that make reloaders lives more interesting. I think the majority of us are tinkerers and enjoy the challenge. It does sound like a interesting video topic. I will have to look and see what I have in stock to work with.

[@jimhans1]

BT, canister powders for off the shelf retail sale are usually +/-8% of nominal burn rate. If you do you development with a slow lot, then run out and your new can is from the fastest lot, you could have a 16% increase in burn speed, and with that, an increase in pressures. If your load was near max to begin with, that extra pressures could put you way into over max territory........ Most if not all reloading manuals explain that ANY change in components for a load require a safe work up again......

If you have to go to a new lot of powder, simply reduce your starting load a couple of grains and work the load up to the previous velocity area a few tenths at a time using common safety practices and a chronograph if you have one. There may be a small change in the required powder charge but it’s usually nothing dramatic. I personally have seen more pressure changes and spikes with primer changes than anything else.

@@jimhans1 I guess it's been a while since I got in the manuals but I didn't know specific lots would make that big a difference that is huge thanks for the info

[@monkeyking9291]

well, the most important thing is ----------primers still on sale

[@Phuh_Queue]

Small rifle primers are the same as small pistol primers

[@user-lu1xi5mu5t]

What I don't understand: how can you go to the shooting range without having checked every single cartridge beforehand? No primer? That would never happen to me! But I'm just a picky German...

[@BoltActionReloading]

It had a primer when it went into the chamber. It came out when it was ejected. (over pressure)

And a funny German too.

[@braddaktar1182]

I only use small magnum rifle primers in peterson small primer or palma 308s, best performance and consistently

Hi Brad, Don't tell everyone the secret. I need to find some CCI-450s. (I am down to about 150) Thanks for the comment.

A couple of things to keep in mind about QuickLOAD. One is, as the instructions say, it assumes the mildest primer you can get is used. Also, its powder characteristics are based on closed bomb testing of a sample that is purchased off the shelf like any other and it can be different from your lot. Some updates to the database have resulted from testing additional samples, but you can spot this in some instances when you look at two powders that you know are the same except for the branding, like 296 and H110, and the powder data differs a bit. You will have to play with burn rate and starting pressure and maybe even energy content of the powder or the weighting factor a bit before you get a good match to what you actually are using. I always try to keep in mind Homer Powley's statement: "First contemplation of the problems of Interior Ballistics gives the impression that they should yield rather easily to relatively simple methods of analysis. Further study shows the subject to be of almost unbelievable complexity." The bottom line, as you concluded, is testing is essential.

[@BoltActionReloading]

Testing is always needed and just as soon as you think something it will find the exception for you. Thanks for the comment.

I really dont consider a cup and draw bullets great for hunting deer and elk. Nosler partition bullets perform much better. The real gunsmith has a great vdo on bullet construction

[@timhofstetter5654]

You actually own a plastic press?

Any serious loader will not step outside of the recipes . if u do u should not load amo on your own ..

[@BoltActionReloading]

Hi Gary this load is based on data from Berger. 49.8 gr of RL-26 with the 135 CH. Berger does not specify a primer so not sure how to help you here. The problem is with changing lots of powder and swapping primers (cause I was out of the lot I had been using) and not backing down a little.

[@garydean1983]

All this is b.s. . unless u have the capability to test muzzle pressure

[@BoltActionReloading]

Hi Gary, Funny you should mention that. kzbin.info/www/bejne/gZawq6Rpj8qjj8k

[@kerbyfab]

Come on man.... you just tryna to show off all your primers! 😢😭

[@BoltActionReloading]

Yeah those are all the different types of primer I have in stock, surly I have no more than that.

Save the jargon & just show the groups
