Re: Who makes a replacement barrel for a 22LR 40X?
I belong to a rimfire shooting club and we shoot a 50 yard match every week and a 100 yard match once a month. We normally have 14 or 15 shooters for any given match and usually 10 to 12 of those shooters are shooting either an Anschutz 54 or 40X, with those being about evenly divided. I consider the Anschutz 54s and 40Xs to be about the cheapest way to get into a real match grade rifle.
From what I've seen over many shooters is that the only way to get these rifles to be able to consistently shoot into a 3/8" target is to feed them right. I take any claims of shooting .5" groups all day long (or with any consistency) with any typical rifle with typical ammunition with a huge grain of salt. I have to call BS on most claims, just based on my experience.
Just saying that you tried Eley, Lapua or RWS and got bad results really doesn't say anything. You really do have to do some hunting around. I've found that changing lot numbers affects accuracy as much as changing ammunition. What I'd suggest is that you get in touch with a place like Killough's or Champion's Choicez and get them to put together a brick of your chosen ammo containing 5 to 10 different lot numbers. Find a lot number that your rifle likes and order a lot of it.
For those guys with the rifles that will shoot .3s and .5s consistently at 50 yards with less than premium ammo, all I can say is you'd better hang on to that rifle, because it's really special.
