[QUOTE="nso123, post: 5693571, member: 2508"] I will throw some things out that might help. For context, I have shot Steel Challenge for several years and am currently a grand master who is sponsored by Magnum Research. I shoot their Switchbolt (10/22 clone) in matches. My rifle is speced with a looser chamber for the purpose of reliability. The match chamber that many are discussing is also known as a Bentz chamber. For accuracy the Bentz is king. It is tight, and can cause feeding issues in a semi-automatic when shooting fast. Our team rifles had this chamber initially and refused to run fast. The chambers were reamed slightly larger and we were all good. Now, as far as accuracy in a rimfire goes, ammo plays a huge role. It’s not just the brand, it’s down to the lot number that can affect accuracy. For example, Eley is the top ammo in the rimfire accuracy game. When it comes into Texas from England the different lots are tested in a tunnel for accuracy. The best lot numbers are like lottery numbers, and the top shooters have ways of finding out which lots have shown the most promise. If you look on the Killough Shooting Sports site you will see that you order Eley Tenex by lot number in addition to your quantity. At a certain point the barrel is no longer your limiting factor, the ammo is (not considering wind). This is why folks are paying almost $20 per box of 50 for .22 ammo. [/QUOTE]
