Finally was able to take the new rifle out and sight it in. Howa mini action 6.5 Grendel with 20” heavy barrel. Scope is Vortex 4-12x40. I really like the rifle, even though I prefer a wood stock. Trigger pull out of the box is 3 pounds, good for my purposes. I did not like the polymer bottom/trigger guard assembly so I replaced it with a nice aluminum piece from DIP. This rifle has a great balance and shoulders very nicely. Having done a rough boresight I was simply waiting for a day when weather was reasonable. Went out last Friday morning, good day, little to no wind and temps at a balmy 28, but plenty of snow! Sighted in really quickly (3 rounds) and shot great. Really smooth bolt. But after a half dozen more rounds it seem to spread from 3/4” to about 1.5”. I know the barrel was not heating up because I was not shooting fast at all. Was going to re-torque the rings and realized my tools that are always in my range bag were still at home on the bench. :frown5: I always re-torque after shooting a few rounds because initial vibrations from shooting tend to settle things a bit, and since I initially installed in 70 degrees and was now at 28, metal contraction can be a factor too. Snugged everything up good while it was cold and now itching to run it some more.
