Bear Creek Arsenal Complete Uppers

[Twkenny]

Gunscrubber on the inside of the necks seems to have done the trick.

In better news, I turned out a 0.79" 100 yard group yesterday!

I had been using Nosler 120 BT and 129 ABLR and starting loads to see if I could get any decent groups as Nosler was suggesting lower end loads were more accurate in their test barrel. I got some 129 Hornady SP in the mail Friday and got the same results. Averaging 1.75" groups with 8208. Well, I bumped up another half a grain with that Hornady bullet and it tightened right up.

Now to do a ladder with both 129 bullets and see if I can get better with the Hornady and to see if I can find what the Nosler likes.

I finally have some hope for this BCA.

Sounds great!
Mine seems to like 120 Barnes TTSX the best out of all I've tried. I'm going to try some different powders and loads and see if I can tighten up the groups a bit as well. Shot a 3/4" 5 shot group in the wind and rain. Not sure how much more i can expect from a low priced AR Upper.
