RUG1, you can't go wrong with the 22lr match. As TCMan stated, they're extremely accurate. As a matter of fact, (unless I'm bad wrong)if you order or buy a T/C 22lr, it will be the match chamber. The only way to get a standard chamber is to order one through their custom shop and it will cost more....Or you can get one from other custom shops.
If I'm wrong on this, somebody please chime in.
