Hello. I just bought a Savage smokeless muzzleloader, that is second hand. The original owner told me to use Accurate Arms 5744 powder. I cannot find any of this powder. Trust me, I have tried. A buddy of mine gave me some SR 4759. He used it in his Savage smokeless muzzleloader. But he sold it years ago, and he cannot remember how much he used in the gun. Does anybody have any load data for this gun / powder combination? I will be using 250 grn. XTP's
 
I have been using 43 gr of SR4759 with a 250 grain bullet in mine, but *USE AT YOUR OWN RISK* as I can't remember where I found the data. I do have some data in my owners manual for Imr 4227, AA-5744, and Vihtavouri N110. If you PM me your email address I could scan and send it to you. I had trouble with the 4227 in mine not burning consistently so I stopped using it.
 
Thanks guy's. You have given me enough info, so I can start shooting this gun. I hope that I get a nice buck with it in this years muzzleloader hunt.
 
43 is really light. Still more velocity than most muzzleloaders but the savage can easily handle more. From what I recall that bullet with black hornady high pressure sabot and 55 grains was around 2500fps. I would start around 50 but that's me. I did a lot of research and doug's message board where loads were pressure traced. That load would likely be lucky to make 40000psi. Guns are proofed to 120000psi. Quite a safety margin. You will blow a sabot long before a barrel. 4759 is my go to powder. Try a 225 FTX with the black sabot around 55grains. You will thank me later.
 
H322 Was also.listed powder
But I'm unsure of recommended load
I did know a gent using the 4227 and said it worked great
In his as he was shooting out to 200 yards with ease
If memory serves me he was using the xtp bullets from Hornady
240gr in a sabot
 
Rusty wood trading company in BC has the AA 5744 in stock. However be prepared to pay the big bucks for it. 1lbs of powder will be around 100 dollars shipped to your door. I have the savage as well.

Here is my load that is working great.
44 grains for AA 5744
Black MMMP high pressure sabot
Hornady. 300 gr xtp mag
Winchster 209 primer

No smoke no mess no corrosion. PRICELESS!!!!!

The 4227 worked if the bullet/sabot was a tight fit to the bore, but when I switched to a different combination that was easier to load I started getting misfires.

If you're talking 4759 powder then 50 grs as a starting load and working up is way too much powder and will result in blowing sabots thereby affecting accuracy. It isn't recommended to exceed 47 grs. 4759 is a faster burning powder and produces higher pressures. The recommended load of 43 grs is right out of the savages recommendation and all loads recommend the use of 300 gr. bullets which is what the 10 ml11 was designed for and it produces speeds around 2300 fps approx. 35k pressure.
I've had excellent results with slower burning powders , specifically 4198 in either imr or Hodgdon and that was at 65 grs being the sweet spot for my gun speeds were just under 2300 fps (2275) and pressure traces measured in the 40K range.
There have been documented incidents of savage barrels blowing and they were still using saboted loads.
 
I played around with H4198 and knurelled 265 gr Barnes for a while and was getting 2650 fps. They were just a bit erratic, but thinking back on it that could have just been a warm barrel. Smokeless muzzleloading has a different learning curve. Because of time constraints I went back to 43 grains of SR4759 and a 300 grain SST in short black MMP sabots. Turns out that with 2 rifles,several years, god knows how many deer, and such things as two deer with one shot, and my daughter plastering a bull moose with that load there hasn't been any real good reason to switch.

Something to note when working up loads in a smokeless muzzleloader is cold bore is everything. Its not so much that the barrel minds being lukewarm, but such things can give a plastic sabot fits. A great deal of time can be spent playing with loads, when it is quite possible that the ML would have put 3 cold ones in the same hole. I spent some time chasing my tail, trying to fix something that wasn't broken.

Unfortunately, one good reason to switch is Hodgdon no longer, and has no plans to, manufactures SR 4759! Hopefully you have a good supply.
