I have a S&W M&P15 in 5.56 NATO. im looking to reload my ammo for this gun. any problems shooting reloads through M&P15's? Is the brass itself any different between a .223 and a 5.56 round? Thanks
I don't think you could double charge a .223 case without noticing it.If you reload correctly no problems. If you accidentally give one cartridge a double-load, your rifle could explode in your face!
