I have both, they shoot about equally well [both have some loads with BH209 that group under an inch when the operator is shooting well] the big differance between them to me is the easy capping and the speed breach. The speed breach is as good as advertised there is NO blow back on mine and you can take it out with two finger which makes complete cleaning in the field a joy instead of a pain. Mine averages slightly higher velocity and I believe has a smaller standard deveation in speed. Hope this helps. Lee
