I shoot a browning BPSR in 40/65, i use starline brass that is nickel plated, i full length sized it when it was new because i wanted to build up enough pressure to blow it out to fit the chamber.
I like the nickel brass because it adds to the thickness of the brass enough so all i have to do is slide the 400 gr. snover bullet down and seat it .40 over the walters wad and 60 grs. Swiss ctg. grade powder.
The nickel brass is also a lot easer to clean, i just drop them into a jar filled with 1 part simple green 1 part murphey oil soap and 1 part water, this is the same thing i clean my barrel with between matches, you dont get the rust you do from useing peroxide and alcohol, all i do with the cases is run a nylon 45 cal. brush into them and dry thrm and run in the tumbler, a lot less work than some people go through, i talked about useing simple green on the old shooters sight, now it seems lots of people are useing it, sure does help with the smell when your cleaning them in the kitchen sink.
