I came into some Remington 7-1/2 small rifle benchrest primers. I'm getting about 90% to fire first time through in my carbine. Of those that fail most light off on a second pass.

Any ideas how to give the firing pin a bit more force to set these off more reliably? Is the 1095 firing pin spring stronger?

All the Best!

Why are you using small rifle primers in .40 S&W?

Yeah, no. You're using rifle primers. The firing pin springs are what they are. SRP are designed for the higher pressures and harder pin strikes from a rifle round. The cup is much thicker. I think you're lucky to be getting 90%. I would pull those rounds down and reload with the proper materials.

Just because you can do something, doesn't means it's a good idea.

OP, just because you're shooting a carbine/rifle that uses "pistol ammo", doesn't mean that the primer you're using is designed for pistol ammo usage. You're still shooting a pistol ammo'd gun that just happens to have a longer barrel that can generate higher velocities with that pistol ammo, compared with shooting the same ammo in a short pistol barrel.

I understand and I hope you do too, that with the short supplies/deliveries that people want, don't use incorrect products you can get or have on hand to satisify the need.

OP is full of shit.

He posted this same thread back in May and was at 80%. Then he was encouraged by several members to load with the SRP's because they do.

He even posted having to modify another handgun to get them to fire reliably.

I was speed reading and missed the rifle part. Lol. After going back to his 1st post about it I remembered reading others trying to help him. Now since it a rehash from his other post is this a fake account from the EOL or is this guy for of it?

No clue. He seemed to be an experienced gun guy and have a decent knowledge of reloading based on what I saw in the original thread.

Trying to figure out WTF this is about? I have a legitimate problem and was asking for some opinions to possibly get more reliability.

And yes. I had about 80% reliability in my 8040 until I put a stronger hammer spring in it. It's about 100% at this point.

Why do some people just have to be jerks? Or perhaps you need to slow down and read things more completely?

Let's see, regular use with regular pistol primers will eventually (probably?) bend or break your firing pin. Those firing pins are made out of belly button lint and turkey poop to start with.
A heavier spring can cause what?

1. Destroy the firing pin
2. Over power the sear?
3. All of the above.

You're repeating the identical thread you already posted about 8 months ago. Do you think the answers will change?

The springs are what they are. Stop using rifle primers in pistol ammo and you'll get better reliability.

That's all the advice you need.

Why do you have to ask stupid questions twice? Maybe you should load ammunition the way you're supposed to and you won't have these issues.
