just for kicks and giggles tonight i loaded up 10 rounds of some 165g cast powder coated spitzers without gas checks over 19 g's of imr 4198. got 1800fps and was skipping a canning lid across the ground at 125 meters. the accuracy shocked me. makes a nice plinking round in my AR.
that was the heaviest bullet i could find data for, and it was in the Lyman cast bullet manual.
just FYI.

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
