This was where I stopped, barrel was very warm, not sure what to expect from this. I packed it up, went and cleaned and loaded more for later on. Sun started to go down a bit, it was hard with the chrono to get it set up properly.
48- 2755,2743,2766,2770 48.5 2791,2789,2731,2859 Not sure what happened here, I shot the first four, then switched to my 338-06, so it was not steady fire, but that last one really threw off the ES.
Then I did another group with the 338-06 and shot my last four, only two registered 49- 2850,2895
At no time did I see any pressure signs, no flattened primer, still had room in the case. I am going to scrub the gun down real well and go up even more. As far as I can tell with research, Varmint powder is very similar to the old Reloader 12, which would put it on par with Tac in the burn rate chart. Next time I go out, only cold bore groups will be shot. I will bring some ice with me to cool the barrel, keep the rounds out of the heat.
Environmentals - Down East Maine, 75* weather, 90% humidity, hazey day, moderate 7-9mph 12 oclock wind. Best groups were with 45.5 and 49. Will post back with more data.
