Where is a good source for 223 ammo? I want to get one round that I can use for target and varmint hunting, so I'm thinking hollow point in 60 or 62/63 grain. Black Hills ammo, maybe?? Also I'm looking for hollow points for my 243. Also, would like to hear comments and recommendations from any and all 223 shooters here who are proponents of the round and their rifle(s) they shoot the 223 with.
