    Reloder 7 in the 45-70...

    I have no personal experience with it...but the question gets asked often enough, and I have seen lots of people say its good for high velocity with moderate pressure...I am curious, but no factory 40,000 CUP load data is available.

    Load data please...powder charge, brass, primer, bullet, OAL, and muzzle velocity if you have a chrono...no estimates please.

    Thank You

    405 RN cast: 40gr R7, Federal match mag primer, WW or RP cases. 1700-1750fps
    400 Speer FN: 45gr R7, Federal match mag primers, WW or RP cases, 1750fps

    I increased the cast load to 42.5 and it got brutal on my arm.
    Might be on or over the edge for a safe load

    Ridge I've used RL7 in my 45-70's almost exclusively for years, it is a great powder for this cartridge. I use WW cases and the Speer 400 grain soft point. Start at 45 grains as was suggested and let your ability to stand pain be your guide....grin. My load pushes the Speer 400 grain soft point over a chronograph an average of 1967fps for 3 shots. It kills on one end and maims on the other, nothing can stand up to this load, I carry it in griz country. I don't use that load for anything else, it's just too nasty to shoot....smile. I like the 330 grain gould hp for deer over a mild charge of 2400.

    I only use RL-7 for the 45-70 loads.

    Pile-Driver 525 RL-7 40gr 1615fps Starline cases WLR primers COL 2.557

    Hornady 350 FN RL-7 50.5gr 2010fps Starline cases WLR primers COL 2.550

    This Velocity is from a 1895GS (18.5 inch barrel) at about 12 feet. Anyone thinking about using this data should start 10% lower and use a crono. The loads are above SAAMI listed for the 45-70 so would be +P.

    Anyone listing loads/velocity should also list your barrel length used.

    Sorry Ridge, I'm using a 22 inch barrel and speeds are 10 feet from the muzzle. I can't control the straight grip guns under recoil nearly as well as the pistol grip guns.

    Ridge that load is plenty accurate too, 3 shots into 1 5/8 inches at 100 yards with the factory irons will do...smile.

    Re: Reloder 7 in the 45-70...

    Well, shooting "brand X" - RUGER #1 with RL7, my hunting load this past Fall was 55grs. behind a 355gr LBT/WFN boolit for a velocity of 2290FPS.

    Recoil no big thing, very shootable.

    I have installed a very nice - thick/soft - recoil pad, but the rifle with a 2X7 Leupold is still quite light.

    When I first shot the rifle, with iron sights, it really beat my face, VERY PAINFUL!!!!!, but once the scope was installed and the higher eye/head position being used, the pain and suffering was a thing of the past.

    Before I got the scope in place, I wondered what I had gotten myself into as the rifle was JUST NOT!!!!! FUN to shoot! OUCH!!!!!!!!!!!!!!!!!

    Still looking for better groups, so have some other powder to test, but RL7 is the best I have seen to this point.

    Keep em coming!
