You betcha. The Greek HXP is what's hanging in my 2$ Garand Tac Vest right now, and the mixed headstanp LC at $70 per can of 250 is also a very nice deal...and just the right quantity for M1919A4 links.
I'm not real thrilled with the Mexican .30 Carbine ammo the CMP has been offering, but GI LC in carbine strippers and bandoleers is available, if pricey.
Conveniently, Camp Perry is a mere 214 mile drive from where I live right now.
