I'd have to look the numbers up again, but there isn't, as I recall, a lot of difference ballistically between a 35/303 and a .375 NE. The 35/303 should drill deeper. If I didn't want to have a .375, just for the heck of it, I'd probably just stick with 35/303 for oddball rifles. It does feed reliably from military magazines. Financially, there's no way to justify building exotic rifles, but I'm going to do it anyway, just because I can. I'll have beautiful pieces I'll never get my money back out of.
