Well, I took my 700VS 223 out yesterday on a very nice day almost no wind and no mirage to speak of, shooting at 100 yds first trying some Rem. 50gr.power-lokts,(unfired brass BTW) had the bullets seated .010" off the lands with Benchmark powder and one load of H4895, best 5 shot group was .830" with the latter, worst 1.132" so I said **** on it, I'll shoot at 50yds to take (any) wind that was there out of the equation, didn't notice anything over 5mph while shooting, then I tried 53gr. Hornadys with H335, ranging from 24.5-26.5grs. of powder, about .008" off the lands, the best I could get was .279", at 50yds, my Cooper 22LR. shot almost that good with Wolf Match Target ammo, my question is, my neck expansion was measured at .244" loaded and .253-.254" fired. How much does .010" neck expansion affect accuracy on a rifle like this? Jay
