Buy whatever is cheap, and your range will let you use. I bought almost exclusivly Monarch FMJ, but I was limited to shooting it on the farm, as our range does not allow FMJ out of centerfire rifles. I really liked Silverbear SPs, and I did shoot some Brown Bear HPs....but all in all, I got the cheapest stuff possible.....the Yugo stuff on CLassicarms.us is good, just clean with water, lube, and dry...its listed as corrosive....
