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
Same for me, I am shooting 300g Hornady XTP and Speer Gold Dot with Harvester Crush Rib sabot using 100g of Goex BP in a TC Hawken FL. If you do the math a 1:48 twist will stabilize a .78 inch bullet, so you have to shoot something short. The Speers are exactly 3/4 of an inch. The Hornady is just a bit longer. I am only shooting, sighting in at 50 yards with open sights. I like the killing power of the Speer and the Hornady, much much better than a PRB. I know, I know it is shot placement, but in PA where I hunt with a FL on drives, there are no broadside shots at standing deer, using this hunting method. All a running, all at close range ( < 50 yards in my case).
The Speers penetrate well.
