I have a question for the ammunition experts:

I have a 5.56 16" Noveske barreled rifle that I shoot 62 grain M855 ammo through.

I also have a 6.8 SPC 18" barreled rifle that I shoot 110 grain SSA Match ammo through

I understand that M855 is not match ammo, but it is not near the accuracy of the SSA 6.8 SPC match ammo. Not even close.

Here's my question: Is match ammo really that much better? Would shooting a 223 match grade heavy bullet round (75 grain?) be a better test of my Noveske Recon barrel's accuracy? Like I said, I know M855 is not match ammo, but had no idea the groups would seem so large. I didn't measure, but at 25 yards for zero about 3" with the M855 vs .5" or less with the SSA 6.8 match ammo? That's about 30 rounds each. An awful lot of the 6.8 went through the same little holes.

I'm thinking I should use match ammo for target practice and just save the rough stuff for classes or extreme emergencies. I never realized that ammo choice made such an accuracy difference. With these results I am very impressed with my WOA barrel and a little disappointed in my Noveske barrel. Maybe it is all because of the ammo that the Noveske seems so bad?

Tell me what you think guys.
