I have seen it in other manuals but the Lyman 46th Edition shows a 45.0 grain starting load of IMR4350 producing a velocity of 2277 and a max load of 51.0 grains producing velocity of 2624fps. The Sierra 5th Edition also has 4350 data.
Nosler has it listed as the slowest powder for the 165/168 bullets... at 2502fps-2647fps-2792fps at 104%-995-95% case capacity using 46-48-50.0 grains respectfully ...and the second to slowest powder with the 180 weights showing 108%-104%-99%..at 2488fps-2593fps-2698fps .packing the case with 46-48-50 grains respectfully... It's defiantly a compressed charge...I had good luck using Varget for the 165/168 grainers...and IMR4064 for the heavier bullets..With the long throats on the Handi's...you'll be able to seat the bullets out further than if loading for a magazine...which should drop the % numbers down somewhat..
