[QUOTE="BountyHunter, post: 93027, member: 12"] Dan we discussed this in detail last year on snipershide. It is just that I have found that the audette/ladder with chrono works extremely well, no questions asked. Will the OCW give that much info w/o using a chrono, I do not see how, but obviously it works to some degree. So yes it works but not to the level that I see that I can get the same information with the same number of shots. It is not uncommon for magnums to give their best accuracy as much as 150-200 fps below top end. So it is common to get up to 4 nodes on a barrel over 200 fps spread. THe norm is really 2-3 though. YOu are correct that we often see the one group wonder in this sport, but it is more telling how often they finish in top 10 and how consistent they are. I was 9th for points last year and I only had the chance to shoot 3 matches this year. Took , 4th in LG and 10 in HG at the PA world open and won my relay at the other match, just got beat by smaller groups in the final. The 4th at World open was with new LG that was shooting its first match at 1000 after ladder testing and tweaking of less than 60 rds at 300 yards starting 3 days before the match. So yes, the ladder works extremely well. But like I said to each his own. Bart you will never find me saying anything about the accuracy of a M70. I have built up a couple shooters and the first IBS guy to reach 100 match points (last year) shoots a 98 and M70 actions and does his own smithing, so I know real well what they can do. BH [/QUOTE]
