Man those SD numbers were so bad I really thought it had to improve. I am not going to lie I was hoping for a pic comparison of the 2 springs side by side to see the difference in length. Good video regardless.

I always close the bolt while holding the trigger down (on an empty chamber of coarse) to release the spring pressure while storing, never had to replace a firing pin spring doing that easy step.

Springs dont wear from beeing compressed but from repeated use. The springs are not tensionless when not "primed", so the idea that dry firing (or loosening the spring in the manner you say) does not make a difference long term. Dads rifle has probably sat tensioned for 40 years and it works just as good as when it was new, a Win 70.

springs wear from cycles not compression
@mikelovin7 Жыл бұрын
@@MyLonewolf25 BS, even car and truck springs sag over time with weight on them and NOT just from use. I even seen magazine springs quit feeding from being loaded all the time, I even bought a new follower for a model 9417 that quit feeding the last 2 rounds, and it wasn't even very old, maybe 2 years at the most. So go sell your stories to some young idiot, I'm too old for that nonsense. 🤣

The firing pin springs were fine as you concluded. There is soooo much hope in the shooting community that changing a properly functioning spring, for a new, properly functioning spring will make a difference. Your test is similar to most of the other results I've seen.

Springs wear out from cycling them. But that round count is in the THOUSANDS. Well north of 8000 rounds. Beretta says to replace the recoil and trigger return spring around 5000 rounds. I’ve fired well north of 15,000 rounds through my 92FS and there is a marked improvement in how if functions. But it was 15,000 rounds before I replaced the main spring on the hammer.

Thank you for giving it a try and showing the results. We are all more informed now. How about an application of JB Bore Paste? Maybe the older barrels have enough micro-imperfections that they compound into high SD's? Would be an easy before and after test.

Johnny, what I always thought is that generally, grouping is a function of load and component quality, where good sd numbers are far more load tune, and mainly Barrel quality. You can have sub-moa cheap rifles, but It would be interesting to see if they can hold good sd's, though. I am sure that there are exceptions. Custom barrels may shoot at least half-good sd's with untuned loads and poor grouping, as far as my experience goes.

As a rule, ball powders are going to give bad SD's. I was disappointed in the N120 SD's and that points to a primer issue. Erik Cortina has proven that differences in primer seating pressure (depth) affects ES's and SD's. Of course he is using a $600 dollar tool that has great control of seating depth. I'm not going to spend that kind of money to seat primers, but I do have a tool that has good enough feel so I can stop when I feel the primer bottom out. When I shoot 300 and 600 yard benchrest the ten ring is 2/5's MOA. Low ES's are key to keeping the vertical out of the groups. Since the spring didn't help much, if any, the issue has to be in your loading. As you know, with the right load and procedures, SD should be in the single digits and at worse the low double digits with single base powders. With ball powder who knows, just believe the target and forget SD's.

Don't worry too much about firing pin spring It plays more of a minor roll in accuracy compared to bedding a barrel. The 243 needs a tune up on bedding. Could put it in a better stock. I like to do minor polishing of barrel by fire lapping and using Rem Clean , JB bore paste, or even Brasso. Polish barrel crown when done. If none of that give you satisfaction in your accuracy requirements after load development. Time to rebarrel.

@jodycornelison76537 ай бұрын
Man, I don't like correcting folks much on their shooting, but you should try using the grip on the stock and lay your thumb alongside of the stock and concentrate on your follow through. That will help tighten up your groups. I did enjoy the video by the way.

I have only seen spring-swaps beeing usefull on 22LR where a stronger spring can give you better accuracy. That together with a good proper firing pin. But 22LR is much more finnicy then centerfire as the priming compund is much less reliable.

Typically the only time a firing pin spring is going to cause erratic ignition is when it's broken, not when it's mildly worn. Consistent primer strike is consistent primer strike, regardless of how hard. I keep extra firing pin springs, pins, sear springs etc... for my match rifle in my range box for this reason. If something happens in a match and I, nor my load have changed, that's the first place I start looking.

Thanks for all the great content. Really enjoy your channel!!…In your opinion is reloading still a good option for someone to try to start now? Are reloader and reloading components hard to source? Can you still save enough money to justify your time if you’re a casual shooter who really can’t justify shooting high priced factory ammo?
@williamjordan54142 жыл бұрын
It is interesting to me that the average velocities of all the groups, with the exception of one, increased with the new springs. More efficient burn? Hotter ambient temperatures? I don't know what your case fill looks like with those loads but from what I have noticed in my limited time of reloading, when I can get a powder that gives me close to 100% fill or even slightly compressed my SD's are better. Love your content!

After a new spring (assuming your old one is very worn - you can tell by comparing length of old vs new if they are the same weight spring) you'll have to re-tune you load. If you still have my email, shoot me a note and I'll walk you through measuring primer depth protrusion.
