    Default 45/70: 550 grain Crater

    I just picked a box of these up for my Marlin for bear defense. Anybody had any experience with them? Were you impressed? Any opinions in comparing them to the Garrett Hammerheads?

    IMHO the 45-70 doesn't generate enough velocity to use bullets much heavier than 400 grs.

    The best load for a 45-70 or 457 mag is a 350 bonded bullet at as close to 2100 fps as you can get it

    The marlin forum seems to have the most info for them and it looks to me a around a 1,500fps round
    Now left only to be a turd in the forrest and the circle will be complete.Use me as I have used you

    They should be no trouble for you although you will have a wallop when you squeeze the trigger !!
    Amigo Will is right , I am using H322 40.5 Grains Velocity 1526 with my 550's .

    Looks like about the same power as a 458winmag at 200yards

    IMHO, anything above 450gr in a Marlin just compromises accuracy (follow-up shots) for a limited increase in stopping power. I have found that sticking to 405gr gives me the best stopping power/shootability compromise.
    I now load 405gr lasercasts http://www.laser-cast.com/45Cal.html with 42gr of reloader7. Gives a nice controllable (but strong) recoil and deadly accurate. Achieving MOA with a 2.75 scout scope on my Marlin.
    Got to get a new chrono and I will update on FPS.
