I probably should not say this...
...but, what Calfee allegedly does in choosing actions is pure BS. At some time or other other he has endorsed nearly all of 'em. (I have two he did and neither is worth a flip.) Flash is a good guy and builds a fine action. BUT, I have never seen Flash at a rimfire match shooting his product. Never. On the other hand, you'll have trouble finding a significant match in which Allan Hall did not participate, shoot one of his own actions, and score pretty danged well. I have two of 'em and if they ain't winning, it's my fault - not Allan's. Now, you do whatever the heck you wanta do but if it was me I would choose the one the manufacturer showed up with enuff confidence to shoot.
