Target Velocity

Paul, I'm hoping that I can launch this bullet at 1800 fps out of the .30-30 case also, using a very carefully chosen charge weight of IMR 4198 or 4895. I'm going to do a lot of homework before I try extrapolating a suitable charge; neither my Lyman nor Lee manuals have any .30-30 data for 220- or even 200-grain bullets. In any event I will undershoot my target charge weight and work up to it slowly.

We'll see whether my Marlin 336 likes these. It's got a little faster rifling twist than my old Winchester 94.
