Howa 20" Break-in
#16
I'm getting groups that run from about .75moa, to a couple of groups using older 95sst bullets that were almost 3". most are averaging about 1.25 to 1.5 moa. I'm going to attribute the horrible groups to SSTs made when they still had some issues with the tips being loose. I have shot assorted groups using the Sierra 85 BTHP, the 90 TGK, the Hornady 95 SST, the 105 AMAX (also old bullets) and the 100 BTSP. I've shot the Speer 75 HPs, the 70 TNTs, and even some older Berger 71 bt bullets. I've loaded with Varget, CFE223, Leverevolution, and IMR4895. The 100 pieces of Starline brass that I bought for this rifle are now all through their second firing.
So far, my best groups have been with the 105amax bullets (only two 5-shot groups fired), with the Sierra 85s, and the Speer 70tnt, and the Speer 75s. Those Speer 75s are dirt cheap too! I ran a ladder with them and 28.0 to 28.5 CFE223 looks promising, and worthy of further investigation.
As for the rest, every one of them would be fine for hunting deer at under 200 yards, but we all want that rifle that shoots knots, and it's fun and satisfying when you do finally find the right combination. The search goes on.
