I think if you got PMC down to 3 inches you did good. If the barrel smoothing thing is what was recommended and you have the funds try a few boxes of XM80. Its bi-metal and get you some big targets and go enjoy yourself. I have an M1A that aggravated me really bad but when I finally decided to pull off the scope and burn through a few hundred rounds of xm80 on milk jugs I enjoyed myself more and the rifle smoothed it self out as a result. Hope it works out good for you. You'll like Australian ammo if your rifle is like mine.
Hi and thank you for your recco of the Austrailian. It looks to me they are running the Sierra bullet in both 165 and 168(game king, match king). Can you confirm?
I found a listing for them on Cheaper than Dirt and they were not terribly expensive. Def worth a try.
At $14 per box for the Freedom Munitions reman 168 amax and only slightly more for the HPBT Match, which once again appears to be Sierra, these are also options. I am cheap! but within reason, you know.
I have not yet found a good supplier if xm80 to try. Do you know one to recco? I tried that ZQI stuff which is supposed to be nato spec ball, it sucks! It runs but it sucks in accuracy it seems.
