I bought an FN Mauser on line cheap. It has a highly figured maple stock and an aftermarket barrel. The owner did not know for certain the caliber...only a 6MM bore. Well, I had the barrel cast and it is a 6-284! I was planning on building one of them...now I don't have to. Suggestions on a load? I think I am going to use Berger 115 grain and 52 grains of Reloader 22 to start. I need to recheck the twist, but I believe it is 1:9.
