Official Savage 10 ML-II Load Data

I use h4198 powder, 325gr .458 Hornady ftx bullets, Harvester black crushed rib sabots and federal 209 primers in my Savage 10ML-11 (stainless laminate). Average velocity of 2240 fps and 1.5" groups. Sorry, no data for 5477. I switched to .458 bullets and HCRB sabots after I ran out of the MMP short sabots. My barrel is .504" and other combinations I tried were too loose in my barrel.
 
I used 43 grains of SR4759 pushing a Hornady XTP or SST 250 grain bullet. Pretty accurate and effective for me. That is the factory recommended load.

LOAD DATA Approved new load data for Muzzleloader 10ML II Due to customer reports of difficulty in finding some of the recommended propellants in the owner’s manual, we have developed the following additional 10ML-II loads. These loads do not replace the loads from the owner’s manual, but rather give our customers more options with better availability. In addition, in response to customer requests Savage Arms has manufactured a limited supply of muzzleloader components (breech plugs and vent liners) to replace worn or damaged parts. Please contact Customer Service at 413-568-7001 with any questions.
