[QUOTE="Bart B, post: 508105, member: 5302"] BH, in highpower/Palma, when one says they've got a .6 MOA rifle, they mean that's the worst it will do. And they typically shoot 15 - 20 shot groups to test it. That's cause that's what they shoot in one string of fire. The best Palma hardware averages .4 to .5 MOA. at 1K. And once in a while, they'll shoot 5 holes clustered in under 2 inches, with aperture sights. I don't know what a long range benchrest rifle will shoot for a 20 shot string. Or even a 30 shot string. Here's what my Palma rifle (with 20X scope for aiming precision) did at 800 yards for 20 consecutive shots: [img]http://farm4.static.flickr.com/3614/3394146444_2d5f4c3e52_m.jpg[/img] That's about .41 MOA. Best I could hold was about 3/4ths inch wobble area slung up prone with the rifle stock's fore end and toe on a rice bag. Here's two 15-shot groups shot with my Win. 70 chambered for the .30-.338 Keele Long Neck. 190 grain Sierra's alternately with 200 grain HPMK's. All 30 shots in aboiut 20 to 25 minutes. Hold was about 1 inch in area shot the same way as above. Note each 15-shot group is virtually the same size; about 6/10ths MOA, but the 200-grain load shot lower on the target. Shots with each bullet weight were alternately fired to check accuracy over a 30-round shot string. Note the 200-grain group was shot with new uprepped cases; the 190's shot with 2X fired full length sized cases.
