High Standard Magazines

[Pentathlete]

Does anybody know of a So. California area gunsmith I could count on to dial-in my High Standard M107 1980 Olympic Commemorative .22 short? I am having a devil of a time fine-tuning the magazines. I've done my homework, including reading what Doug White published. I understand the theory. I have the adjustment tool and a micrometer. I even paid a gunsmith to try. But I still get about 4% failures to feed. All high with one and all low with the other. I know what needs to be done, but still can't seem to get it right. I shoot aggregates in the 250's with a goal to bump that up another 20 (NRA Winchester Conventional Bullseye Pistol Distinguished Expert). Getting this beauty 100% dialed in so I don't have alibis just about every 30 shot aggregate would mean a ton to me as I'm almost 70 and not getting any steadier! I can be reached at roger@basicgunsafety.com. Thanks!!!

I'd ask a mod to move this to the rimfire forum.
Also if no luck check out rimfire central. They have a HS forum http://www.rimfirecentral.com/forums...splay.php?f=49
