Splitting Brass
I recently "inherited" 1000 rnds of .41mag 210 gr HPs. When I tried them out, 75% of the cases split just behind the bullet seat. I fired about 20 rnds. I then fired 50 rounds of factory ammo without a hitch. the reloads don't appear to be too hot, judging from the recoil. Will the splitting cases hurt the cylinder? After cleaning, there was no physical damage to see. Do I throw 1000 rnds in the trash?

Re; splitting cases
I should mention I'm using an old 3-screw Blackhawk, very strong.

If they fired ok w/ no other apparent excessive pressure signs, I would go ahead and use them. But, I would then trash the empty brass after firing them. Brass is much softer than your steel cylinder chambers, so I doubt they could be damaged in anyway.

Why ruin the brass? Pull the bullets dump the powder and deprime and resize. Load with something that you know for sure is correct.

Sounds like the brass is brittle. It would have to be annealed to save it which means all those live primers would have to be pulled.

Not likely to hurt you or your gun. Might spit a little powder or gas back past the case so wear eye protection(always). Cases might be splitting because the brass is old and brittle, or reloaded to many times, or to hot, or combination of them. Odds are good that if you pulled the bullets they would still split(been there done that). I'd just shoot 'em.

Thanks for the input. The reason I was concerned was because somebody on the firing line mentioned that the splitting brass could "stretch" the cylinder walls. And I'm not set up with any reloading equipment right now. The downside of renting.
