I think I have only ever heard 2 complaints about the model 70 action and that came from target shooters.
1. There are no decent triggers available - well, there are now!
2. The flat bottom action is not as easy to glue into a bench rifle stock as the round bottomed Remington - as a hunter, so what!
I have both, like most people. I have seen more issues meaning jamups, misfires, sloppy bolt movement, bad triggers, poor erganomics relating to the bolt, feeding issues coming from model 98's that every other action combined.
But I own them.
Nothing like a slick push feed I guess. I have a PF .458 that is as slippery as a honeymoon erection. Sold it once and bought it back.
