Thanks for your replies. I'm sure I'll be posting more info and questions as I get some time to shoot. So far I went threw 40 rounds of rem factory 117g. All shots would have killed a deer at 75 yards, but no great groups. I'm using the open sights as I have not decided on a scope and rings combination yet. I'll start a new thread to address my scope thoughts.
my rem had a 3x9 leupold on it when i bought it, but i have since put a 2x7 leupold on my rem 722 in 257R, i shoot 44grs imr 4350 with the 115gr bullet and from a good rest it will put 3 into a inch at 100 yds. and as you can see in the last photo it works on deer. eastbank.
I have a vintage #1B. in 257 Roberts. This is a heaver rifle. The actions are all pretty much the same. I have no problems loading a heavy charge of IMR4350 and a 100gr. Sierra Spitzer for 3200 fps. with excellent accuracy. Have at it with the +P's.
To the best of my knowledge, all Ruger No. 1s are built with exactly the same action. Some might say, over built. That is why Regan Nonneman can re-barrel and/or re-chamber any No. 1 to any cartridge your little heart desires. Here is a link to his site. Check it out.
