cataway
I shoot 300 grain Speers in an HPH-24 sabot just fine from all of my 1/48 barrels. Both Renegades, a Lyman and a couple of Hawkens... i have not had much luck with lighter and shorter bullets but the 300 Hornady or Speers shoot right where i am pointing... 80 grains of T7-3f in the 50's and 90 in the 54's
