I read with interest a previous thread about this. So...I tried pulling some Romanian and some Czech(?) with an RCBS collet puller. No go. I even bumped the bullet down a bit to break the seal. No way could I get that collet to grab tight enough.

Tried some copper washed surplus, origin ??. Popped out, no problem. Averaged out the powder from 5 rounds, dumped it into 5 sized, never fired .303 brass, seated the bullets.

Took my old quasi-sniper POF out to my buddy's range, fired them off. Didn't spend any time or effort to "sight it in", just wanted to check recoil, etc. Worked really nice.

I also dumped 5 gr. Unique in the primed 7.62 brass and seated a 93 gr. WW Lee bullet. Fired them off in my Baikal single shot rifle. They made a pretty good crack, and dirtied up the outside of the case, and of course, the chamber. Not enough pressure to expand the steel case, I presume.

I will do a few more and spend some effort trying to get the POF to shoot to point of aim. Will report back. :)
 
I usually increase the powder charge when doing a component swap. The 400+fps spread makes for extremely inconsistent ammo otherwise.
 
Thanks for testing this out. I was also following that last thread. I also tried pulling some Czech ammo and it did not work. That red seal stuff was working too well.

Then I tired some of the Chinese copper wash as well, it did not come out. I gave up pretty early because it quickly became not worth the effort and had put most effort into the Czech stuff already
