Shoot them in a blowback like a Sub2k or HiPoint carbine. They'll run just fine and won't cause any issues.

I don't own either. Besides, i have a rule about shooting other people's reloads. If I don't know you, I don't shoot your reloads. I saw first hand what happens when someone doesn't pay attention. luckily the guy shooting only came away with a few bits of shrapnel in the heal of his hand. He bought reloads from someone who didn't know what they were doing.

I should probably just google it
I think the primer would back out before the bullet. The pressure inside the case pushes equally in all directions and the mass of the bullet is much greater than the mass of the primer.

I have a collet puller and have used pliers on the Iranian 8MM I have lots of. RCBS collet puller slips most of the time and right now takes more time than the kinetic. Pliers leaves marks. I have to beat it pretty hard with the kinetic right now and its loud as hell.

I also have some Czech training ammo I want to pull and mess around with. Its so light, kenetic does not work and the crimp is also so hard the RCBS won't hold onto it.

I dont' mind paying the $ for this.

Observation #1 - Different bullets of same weight and general shape will have different nose shapes , ie some are pointier, some are more hemispherical . The important factor is how far the base protrudes into the case , the OAL is an indirect indication , unless you are using the exact same bullet .

Observation #2 - 3.8gr Universal is a Start Load ( per Hogdon ) with pressure of only 26,300 psi ( with SAAMI level of 35K ) .

OK , I get it , some people categorically will only shoot ammo they personally loaded . But since I percieve an implication that the level of confidence was sufficient to consider shooting it , I'd look at little further .

Spot check enough rounds to see if the charge is consistently 3.8gr .

Using a gun rated for at least occasional +P , I'd feel enough margin to fire a test round .

If no visable pressure signs , case head expansion in normal range , and velocity in expected ballpark , I'd probably shoot it .

Interesting. Considerably less surface friction on the primer as well. Primers would likely pop first.

26300 when set for an overall cartridge length of 1.15 in. I did some research before I post it this thread and it looks like the pressure increases greatly with just a slight decrease in overall length. 1 reloading forum that I went to for research said that with a decrease of just one eighth of an inch the pressure goes from 27 300 to almost 63000 PSI.. that seems extreme but I'm not willing to take a chance on damaging my firearms let alone damaging my hands. I make my living with my hands. I ordered the horn day bullet puller and Colette for 9 mm. I'm going to see how it works. If I don't like the results I'll just use the kinetic puller and do a few here and there until they're all done. It's not like I'm hurting for 9 mm ammunition. I've reloaded several thousand over the last few months and still have about 10,000 cleaned cases ready to be reloaded

For you guys who pull military bullets, if you press the bullet into the case first, it will pull easier using a kinetic puller. The reason for this is that many military bullets have a sealant applied to the bullet. If you don't break the seal, you may break your kinetic puller before the bullet comes out.

That's a wise decision, IMO. No reason to take the chance.

You could try using pliers, first padding the jaws with thin felt or thick cloth to prevent marring the jacket. Just a thought...

I used to shoot a lot of 303 brass in 30/40 rifles and the brass was always short. I would strip the cartridges and check chamber fit but if your not sure of the loaders competence and cant ID the powder/charge your probably better off pulling them.
If pre-op checks seemed OK and cartridge fit was ok I would probably just shoot them.
