I usually shoot the UMC "mega pack" 45 grain hollowpoint 223 stuff since it is relatively economical and reliable, but I decided to pick up some Remington Accutip boattail stuff to shoot (40rds). I also brought along 60 rounds of my cheapish UMC ammo to compare. Out of the box with no adjustments the boat tail stuff put the first round an 1/8" of exact bullseye (not in the 10 ring, but at the x-y intersection), the follow-ups were pretty close. Turns out my rifle was dialed in very good to begin with so I never touched the knobs. After the first 6 shots with the Accutip I started to get a little 'off' with the rounds straying out of hte 10 ring but within the 9 ring. I remember shaking my head after most of those shots for making mistakes....knew the hole was going to be off even before the smoke cleared The UMC stuff on the other hand, I could never get a tight group with it and it seemed to shoot consistently low (albeit I got a little happy and really got the barrel hot by that point). Anyway, I was happy that my first shot on a cold rifle was very clean as were the follow-ups. Lessons learned or re-learned..... 1. Don't get the barrel stupidly hot 2. Don't try to chase your sights around with a hot barrel and plinking ammo. 3. Plinking ammo can be notably less accurate than the $1.00/rd stuff. (duh). The tube at Bass Pro is also connected to their gunsmith area but seperated by ballistic glass. I looked behind me and the guys in the shop were wearing their earmuffs. It seems my AR is stupidly loud because of the YHM brake I put on it a while back. They normally don't have to wear their muffs even when the 30-06 or .308 shooters are down there Also picked up some Butler Creek flip up scope covers for that oh so tacticool look.
