Some of the least-worst efforts I've managed:
AA MPR / 400 with floating barrel, benched at 35yd outside with AA Express straight from the tin; 10 shots, 7mm c-c:
Same rifle benched at 55yd outside with weight-sorted and inspected AA Express; 10 shots, 14mm c-c:
LH target - Huma-regged, self-set-up BSA R10 Mk2 with ECHF barrel, benched at 100yd outdoors with unsorted AA Express straight from the tin. Around 52mm c-c:
Irritatingly the barrel quality on the R10 is crap and it doesn't group as well as this group might suggest at more sensible ranges..
