[QUOTE="J E Custom, post: 1286106, member: 2736"] Is it because of the accuracy with the 60 grain Subsonic ammo ? I have tried this ammo in many 22 rifles and found that none would group Like the higher velocity ammo, and the heavy lead bullets did not like the faster twist barrel because they did not engrave well and sheared the engraving on the bullet. The only thing that seemed to show promise was a marlin Micro grove barrel with 10 lands. The accuracy was better and the engraving looked better/cleaner on the bullets that I recovered. Normally Lead bullets need a slow twist in order to engrave well. I would very interested if you find out that works. Keep us posted. PS: Something to think about would be a gain twist barrel. I have a 460 S&W pistol that shoots very large bullets fast and it has a gain twist barrel in it for the big bullets and is not hard on thin jackets. I am still trying to verify what I have been told about the twist rate (S&W says it is a 1 in 100" to a 1 IN 20" twist). That sounds crazy but it shoots very well. so I will believe it when I see it. You might get someone to make you a gain twist that is something close to a 1 in 9 or 10 to a 1 in 12. J E CUSTOM [/QUOTE]
