I was shooting my TC Encore today, getting ready for the MZ season (last minute practice ) and I suffered from what can only be described as an odd accuracy change.
About 15 shots into my session, with a target at 100 yards, my rifle went from 2 in the bullseye about 2" apart to dropping 2 shots low and right about 6", but also in a ~2" group. Nothing really changed that I could account for, other than a shift in light from bright and squinty to dark and dark.
My load was a 240gr XTP Mag Express and 95gr of Goex 2Fg ignited by a new Winchester T7 primer. After the first 2 at 100 I was feeling really good about this combo, but then with shots 3 and 4, I'm kind of worried.
Additionally, this rifle wears an aperture sight with a firesight on the front. Once MZ season is over, I'm giving TC a call and getting another front sight or two in differing heights to fine-tune my elevation. Right now the rear is topped out, which is fine as it WAS dead-on at 100. Just a detail.
First it's going to get a thorough scrubbing and maybe a return trip tomorrow before work.
I was just curious if anybody else has ever seen anything like this happen.
Thanks all.
