How much more performance can one get in a 3.6" vs a 3.3" 300 Win? I have a push feed Model 70 (last year before the CRF), and from the looks of it, the magazine could be unblocked the same way the CRFs can be.
Well, I don't know about total FPS, but it allows the bullets to be started out near the lands. Most of the 300 Win chambers I have been around are quite long and seating to 3.4" really gives them a long way to jump which doesn't always hurt accuracy, but it does make it tougher to find accuracy sometimes with the 200+ grain bullets. Also, with a 3.6" mag box, I haven't really had much trouble getting 3100 from 180's and 3000 from 200's. I could do the same with the 3.4 box, but getting the seating node was a little tougher for me.
