I have heard two different rumors lately and was looking for some input. I have a M4-A3 from Busgmaster and love it. However, I've heard that 62 gr ammo shoots better in it that 55 gr. Has anyone done any experiments- I'm getting some good 62 gr and 55 gr today but was llking for input before hand. Thanks.

I have a BM M4A3 as well, and 55 Gr FMJ is the only thing I've run through it, I'm at about 3000 rounds so far, I don't know why I chose 55gr FMJ, but it works fine
