I want to try to make a 5.56 load that is as close as possible to what the US military and NATO troops use. I would rather load the 62 gr. FMJ-BT But I can settle for 55 gr. Now from what I've read the majority of people say to use H335 powder, CCI primer ( I can't remember if its CCI 400 or 41 that could be wrong.) and any brass with the NATO head stamp. Can anyone tell me if the have a mil-spec 5.56 load for 62 gr. and 55 gr FMJ-BT.
Exact load you will not get they use different powder than we can buy. H-335 is too fast a powder to get you to Mil-Spec speed, you will need to use a slower powder like H-4895 to get the pressures you want.
My standard load for 62 grain FMJ steel core is 25.1 grains of H-4895 at OAL of 2.250 inch with a Win SRP. And be sure to crimp those rounds.
