    I've not really used a lot of 4064 for many years in my M1A/M14s and none with cast bullets. Even back then I preferred 4895 for use with match bullets and cast bullets. However, that's not to say 4064 won't work with your cast bullet in your M1A....

    Ruger would replace the trigger parts with NM parts (transfer bar) and would repair the over rotation if that did not fix the problem.

    I don't want to shoot any high velocity loads may not be compatible with shooting longer, heavier cast bullets in a 1:38 twist. To stabilize those bullets may have to be driven fast. A 240 - 250 gr SWC at 1050 - 1100 fps over 8 gr Unique will...

    Concur. Titegroup is a fast burning, easily ignitable powder that does well with reduced loads. The "safety margin" involved is the danger of a bullet not exiting the barrel. Just make sure to use enough for all bullets to positively exit the...

    Given the larger the case volume along with the smaller the expansion ratio of the 45-70 case the less any appreciable increase in psi will be found between standard length cases and the Hornady FTX length cases. As several have mentioned they've...

    Pressures are measured with special equipment and test guns. It is expensive. Even with factory measured pressures there is no guarantee that, even if using the exact same components, you will get the same psi in your gun. It may be lower...

    From my treatise on my 45-70 trapdoor loads; PART III: I had several reasons for developing duplex 45-70 loads. Maintaining accuracy w/o cleaning between shots or every 10 shots or so was foremost as I didn’t want to carry a lot of cleaning...

    The Lyman SME receiver sight or the M48 sight fits the M96 as well as the M98 because the rear receiver ring is essentially the same ssize on both.

    I concur that the RCBS 30-150-FN is an excellent lighter weight bullet in the 30-30, especially M94s with 12" twists. Your 300 Savage should also have a 12" twist and the RCBS bullets should be excellent. I was also using H4895 in my M94s with...

    If you want a cast bullet that will, after zeroing, regulate to the range settings on the rear sight then the 311359 is the best choice. At 1850 fps it can do extremely well matching POI with the rear sight range settings to 300 yards.

    "I think the twist rate is the killer." That would be correct. The "odd flyers" are the result of the bullet exceeding it's RPM Threshold. The first load at 1515 fps is running 136,350 rpm....The heavier loads are obviously pushing the RPM over...
