I guess this means I either need to buy a 50, or figure out how to load with that stuff, even if it is sub optimal for the application.
I know that this is overly simplistic, but it seems like it is optimized for loads that want to push "light for caliber" bullets at around 3 000 + fps.
Does that sound like a place to start looking for loads ?
This prolly ought to be in the reloading sub forum, but I'll give you a shot out anyway.
I've loaded some
of the offerings for the 50 cal (incidentally not h50 BMG) and they can be loaded in calibers such as the 7rum, 300rum, 7mmstw, etc..
You need a rather overbore round with a rather heavy bullet to make the offerings for the 50 Browning work well. I've used rl50, wc872, I5010, aa8700... probably a couple of others too...
