I have almost a thousand rounds through my RAR in 22-250. My complaints are the feeding from the magazine is terrible and the trigger is pretty gritty. May have to try the 450 bushmaster magazine.
The Bushmaster mag is on my list too. The only two rifles I own that have feeding issues are both based on the same case; the Ruger American in .22-250 and a Savage in .250 Savage. The case is just short enough and with enough taper to cause the rounds to feed into the bottom rear face of the barrel.
