I'm new to the .223/5.56 and need to buy some ammo for my new MSAR STG. I'm looking at the following:
Federal M855- 62gr
.223 BTHP - 68 gr
.223 VMax - 55 gr
Is the M855 good ammo to go with? Is it only practice target ammo? Any negatives with it?
Any suggestions on ammo and it's availability would be helpfull. Thanks.
