gas check

I would gladly pay the difference for copper gas checks.

All true, but there are arguments in both directions.

If you use aluminum gas checks and the check oxidizes before you shoot the round, in my mind you waited entirely too long to load and shoot the bullets. I am not trying to be smart, I just know that aluminum oxides very slowly in most environments.

I would use the aluminum checks and never look back, were it me... If you happen to find a bullet with an obviously oxidized aluminum check on it, pull it off and re-check the bullet, or re-melt it. No harm, no foul.
 
Let me ask another question. I am casting a 150 grain wheel weight, with just a little lead and tin. Bullet seems about the right hardness,about what I used to shoot in BPCR. Shooting out of a 30-30AI.Both lube and alox. The rifle only has 16 inch barrel. What kind of velocity do you think I can get away with.?
 
I used to get 1325 out of my 40/65 with a 400 gr bullet and Swiss powder. I was hoping somehow to be able to get more velocity but I bet you are correct. Did you ever try Swiss Black powder in your BPCR rifle? Burns cleaner and much more consistently than any other I tried.
