last weekend i took my TC 50cal hawken flinter to the range to shoot while my 22-250 barrel cooled. 25yds i shot a clover leaf. it was an inch-inch and a half high. 50yds, target was identical. 1-1.5" group and high. i know it was sighted in dead on at 50yds. i dont shoot past that with the flinter..the recoil was also more than i remember lol. never did i think a roundball "hurt" but it was whackin me good that day. it was 90 degrees out. i sighted in when it was 30-60 degrees..i cant remember but im sure it was cold out. i know pressures are higher with smokeless powder in hotter weather. is the same true with BP?? that would explain higher groups and heavier recoil...i didnt touch the sights...figured that was the cause and it was shooting well so i didnt touch them...just figured id check...i'll shoot more before the winter season, but just checking...
