cayugad,when looking for a load for the Triumph I tried MMPHPH12 they were so tight I could not load with out pounding them down,MMP-HPH24 loadedok shot 1.5 to 1.75,tried Crush Ribs they shot .75 to 1.2 inch.
This was using 250gr Gold Dot and 100 777-FF with Win standard Primer. I also conducted a swith primer test trying Win 777 primers and 209 standard primer could not tell any differance in residue[the Triumph dont crudring]
Though you might find this interesting,I have come to the conclusion that with a lot of guns the right sabot is more critical than the brand of bullet. Lee
