Painless load development (mine)

BR-4

Not that many failures. Maybe 1:100,000… or more.

Are you loctite your bolt handle is all the way down each shot?

Have you cleaned the bolt out and the firing pin off?

What are you using to seat the primers?

What cases? And did you trim them?

What's the preferred primer seating device? I've got the frankford arsenal hand tool and have had some issues with seating depth and disfigured primers. Had 2 failed firings 2 years ago on a deer hunt. 3rd one was the charm and put the buck down thankfully, but would like to switch to something better.

I've only ever used a rcbs hand primer. Everything from 300 wsm down to 223 and all handgun calibers. Never had a single fail to fire in any of my reloads.

short answer no, but I’ve got the UM short w/ ball and I try to be cognizant of that, it’s definitely down when I recock it

Have you cleaned the bolt out and the firing pin off?

Doing that now

What are you using to seat the primers?

RCBS hand primer

What cases? And did you trim them?

Assorted reloaded factory:
Hornady frontier, black hills tmk, fiocchi .556, federal gmm, and some new starline

I did have to use a primer pocket hand tool to remove the crimp and open the pocket because the primers wouldn’t seat without it on some.

Ok. That is the most common reason for fail to fires.

Doing that now

Good.

RCBS hand primer

Good

I would pick one good make and stick with it while you figure it out- stareline is fine.

Yep. I would stick with one type to narrow the issue down.

Cases that are sized too much is a common issue

Small base dies?

Only issue I've had is with the shellholder version leaving the cups proud and causing resistance on close, the universal version has seemed to be more consistent and haven't had issues in the last couple hundred rounds.

In May I started using the Derraco PCPS Primer Seater. It a pretty inexpensive way to easily set the primer depth and crush you want. The tool is amazingly consistent. Since I started using it my primers are all seated +/- .0005 from target. Whether that level of consistency makes any difference on target is debatable but it has tightened up my ES and SD numbers, It is also very easy to use and fast.

I like this one too if I have a bunch of brass sized. It takes a minute to set up. Almost needs its own press.

If I'm just screwing around I still use a hand primer.

Thanks I'll check it out!

Got a Hornady versaprime gonna fire up this weekend if I get the chance. Assembly looks pretty nice. Should be a good upgrade over hand primer and I think will dial in nice and consistent

Interesting. The shell holder version is the one ive always used. Never an issue. I didnt even know they were making a universal . That looks pretty handy though. I hate switching out shell holders on that thing.

This. I actually leave it set up in my secondary press, a Rockchucker, and only take it out when I need the press for another miscellaneous task.

I have a Rockchucker laying in the garage, time to set it up.

Not sized too many times, sized too small. Firing pin hits primer, case slides too far forward in chamber before shoulder meets resistance.

How far are you pushing the shoulder back.

Every time I have seen people have issues with ignition it was always from too much sizing on the die.

That’s usually the culprit.
A lot of people fire factory ammo which is short anyhow to make sure it fits every imaginable chamber.
Upon firing it is pushed forward by the firing pin and may even come out of the chamber shorter than it went in because it is pretty often piss weak and doesn’t move back to the bolt face.
Now they have read on the internet that it is imperative to have bump gauges and bump back “two thou” or some such nonsense.

It is almost never anything wrong with the gun.
