[QUOTE="Ian M, post: 6290, member: 25"] I have worked with some very accurate 10-22's and found that after tricking out the action to get a decent trigger pull, the most significant factors for accuracy were the quality and uniformity of the barrel crown and the ammo. Had five aftermarket barrels and two factory Ruger heavies, shot them all to establish average accuracies with several good types of ammo, then had the barrels re-crowned by a very good smith and the average accuracy improved - up to 25% for some barrels. Never messed with chambers, too techie and expensive but no doubt some match chambers might be better than others. Could not beat the top-end Federal match ammo, understand it has recently been dropped from production. Some of the most accurate ammo I shot is very old PMC called Zappers, was cheap but extremely uniform. I had a great accumulation of data from all that shooting (over 10,000 rounds) and playing - fried my hard drive and lost most of it. Hell of a reminder to backup your info. Your groups are great, must be shooting in zero wind situation and using good ammo. Interesting to know what that little slug would do out there on a small beasty. [/QUOTE]
