"...44.5 max according to Hodgdon..." That supposed to be 34.5?
Don't load .260 myself. My 90 grain .243 ground hog fightin' ammo likes IMR4350. Uses a bit more powder for 1 fps less velocity. Pressures are in CUP for the 4350 vs the PSI for the 4166.
You using a Barnes manual? Their site is decidedly limited.
