Re: Newby here..... Just a few ????\'s.
I don't test my own BC's. I just can't bring myself to put the Crony that far away from the muzzle.
The BC I've been using for the AMax's is .534, and it seems to be working great for the Point Blank Ballistics program I use.
The Berger 180's have a BC of .698, and it works well with the program too.
I'm working now with some Nosler 175 partitions, showing a BC of .519, and so far it has been on out to 500 yards.
I'm shooting these in a 7 mm Remington Magnum, with a 9.5 twist.
If I can kill that coyote from here, Will you walk out to get him?
