I've XR-100's in both 22-250 and 204. Both are very accurate. As noted before, neither are really 'long range' packages as the 204's 1 in 12 can stabilize only up to the Hornady 40 grainer with it's BC of .275, and the 22-250 tops out around 60 grains - again around the .275 mark. The 204 shares a slightly flatter trajectory, and you can squeeze off about twice as many rounds before the barrel gets equally warm (compared to the 22-250).
The trigger's not 'all that' it's made out to be by Remington. It's better than most factory triggers, but there is still noticable creep. Interestingly, the trigger in my 204 adjusts to a *much* lighter pull than the 22-250's trigger was capable of. Go figure.
