    M-P data for 45-70 suggestions .

    I have a plan of attack now that I've found the 462-420s happy place .
    Black Powder is on the availability list here right above pre-84 Beetle radiators and hens teeth . All of my BP gear is packed for the move next spring so I won't be running any either .

    As for smokeless I have medium fast , slow , magnum slow , and Unique .

    I have an 1895G new Marlin , it has all it's rifling .

    At this point I've run some 458193s , 458-340 , 458-405 up well into Lever gun data and past fun to shoot . A custom 453-350 paper patched was shot over a 454 class load with Unique . What they all have in common is no real group advantage over each other .

    My particular 462-420 drops it's PB at 414 and it's HB at 380 . Thanks to my keen well honed pouring skills it does so +- .5 gr or less .......or I've just been lucky (really the most likely answer) .

    I'd like of course to have a full case and not have to crimp heavily and would prefer to stay somewhere around the lever gun start loads as an upper limit . I've done this sort of with 4350 and 4831 with the 458193 ......great except that the load was coming together as it reached this isn't fun any more but if the bullet holds together I should be able to get an exit wound on a wildabeast as long as I miss the horn root via the Texas heart shot .

    Is the work up line and see where it goes with start loads the fast track or should I be looking for a particular point with the MiHec bullet ?
    It appears to have more drive area than the others .

    Open to suggestions .

    Hogs and AR whitetail but mostly paper and steel . CCI primers and Privi Partizan brass . Redding and RCBS dies . .451×.458 , .459 throat . Except the paper patched feed is a problem before land contact .
    Everything has shot 2-3" from the Privi 405 SP at CIP down to 12 gr Unique under the PP350 for 5 shot strings .
    In the time of darkest defeat,our victory may be nearest. Wm. McKinley.

    22 grs of 2400
    Dacron is optional.
    it's all an educated guess,,,, till the trigger is pulled.

    I use the Lee 405 and 25 grains 2400 no filler. I get great 2" or less groups at 100 with this load.
