Bertram Brass

[ken s]

I bought 60 cases of the .40-70 Bertram brass 17 years ago when I got my .40-70 Shiloh and they split the length of the case after three reloads. I still have some in the junk brass box. The brass is very brittle like they might be made from yellow brass.

Thank you Kurt. this is the information I wanted. I've cancelled the order and will try some of the 40 70s that B Arms has. I've ordered 10 to see if I can size and trim the rim (if necessary) .
B Arms (great Guys that give an honest answer) said that when Jamison brass becomes available again, they will stock ONLY the 40 65 with the larger rim. SO. I'll have to see if I can have them fit. I'll get more if I can make this work..
