    Does anyone have any experience loading a little heavier bullets with The goal of staying in the 1250-1350 FPS ? Say...460 - 485 grain range?

    It looks like H4198 might work as well as IMR 4064. The Cowboy will mostly be just for fun but I am sure it will get a shot or two on deer and hogs this year. My GBL is the opposite. I will use my GBL mostly for hunting and a little for plinking.

    Also, which bullets do you recommend in the 460 - 485 ish range?

    Thanks in advance.
    Panbolio,

    Lyman 4th edition cast manual data. If you are shooting a PBB no gas check, you may need to stay below 500 gr if you want 1,300-1,400 fps. If you switch to a GC design you have more room on the higher pressure/velocity side.

    480gr

    • IMR-4198 Start 28.0 @ 1,350 / Max 32.0 @ 1,420
    • IMR-3031 Start 37.0 @ 1,310 / Max 40.0 @ 1,410
    • 5744 Start 26.5 @ 1,250 / Max 28.0 @ 1,320



    500 gr

    • IMR-4198 Start 28.5 @ 1,1,10 / Max 31.5 @ 1,285
    • IMR-3031 Start 38.0 @ 1,070 / Max 42.0 @ 1,330
    • 5744. Start 25.0 @ 1,080 / Max 28.0 @ 1,185



    PS: These loads are from the Trapdoor guidance where max pressure is in the 17,500 range. Well within safe pressure range for modern rifles.
    Thank you! Thank you!

    Lyman reloading manual #50 shows a bunch of different powders for 480 gr, with starting velocities in the low 1100s to the high 1300s, and lots of points in between
