RE: rem 7400?
My first high power rifle was a Rem 7400 in 270. I still have it and I have never had any problems with jamming. The rifle is very picky with ammo though and any change will send me to the range to check scope settings. Bigcountry I haven' t noticed that the forearm screw causing a shift in point of aim but I will watch for it now. My load for years is 46grs of IMR4604. 150gr Hornady bullet. RCBS small base dies and a light crimp in the cannalure. The cannalure was the reason for picking the Hornady bullet as I wanted to crimp. I recently tried some of the loads for my sons 270 and they shot fairly good in this gun and have me thinking of trying some differant loads in this gun.
