KING,
update, my buddy got a new drop in from green mountain,50 cal/1 in 70.He sighted it in using elephant,very accurate,5 shots in one ragged hole at 50 /irons. he then used my wano,same load exactly,rflie shot dead center same groups but 1 1/2" higher.(more vel,I assume,had no chrony)
2nd test:
with elephant he had to swab after every three or could not load, with wano he could get 8 before it got to tight to load. I am convinced it is due to moer thourough combustion,which would justify less fouling and greater vel. let us know what happens with your test.
