Interesting. I'd never heard that push feed was more accurate than crf.
Be that as it may, I do have some push feed rifles, and some crf rifles. (No Coopers though). I do however have a bit of experience with Kimber Montana's...... I currently have but a single Montana, chambered in the dreaded 7wsm. And it seems to do ok, in that I've done absolutely nothing to it except wipe the packing goo out of the barrel when I first got it.
It seems to be bedded adequately well from the factory. Pretty standard for the few that I've had/shot. I will be adding a 223 to the stable this winter, and possibly a 243, just for giggles.
Shoots 120 tsx's and 162 amax's to the same point of aim at 100 yards, so makes it pretty simple for running drop charts. The last one I had (also in 7wsm) did the same thing.
This is a group on a steel plate shot a 741 yards, 3 162 amax's and a lonely 120 tsx I found left over, on a relatively calm day up here. Shot over a day pack from prone.
I do like the look of the Coopers, and I know a couple of my shooting partners do have them, and love them. I'm personally afraid to try one, as I'm pretty sure I'd fall in love with them as well, and I have more than enough on my plate with trying to acquire more Kimbers......
