I have used Win 296 Ball powder with good results. The powder seems to function well behind 240 gr. hardcast lead bullets or jacketed bullets. Works alright with the heavier 300+ gr hardcast bullets too, if you need a heavy bullet. As for powder charge, I would start a little below the max listed in a reliable reloading manual, and work up from there to your preference. Carbide dies make quick work of loading straight wall cases like the .44.
To my knowledge mine isn't the super. However I can't seem to find my particular one on the Ruger site. Its got a 7 1/2" barrel and is Blued. The Ruger site doesn't show a blued only SS with a 7 1/2". Picked it up from a dealer in CO about 5 years ago.
I have used hornady's manual and its decent to get started with, but is set up for their brand of bullets. The different powder manufacturers have some info avialable. I would think any published manual from a recognized source would be a good place to start. Winchester has loads available on their website for the .44 and is worth checking out. Take the time to make sure your dies are seating the bullet properly and you have the correct amount of crimp. There are other websites that publish loads, but if its from a private individual, take the infomation with a grain of salt. Doesn't hurt to be a little conservative when you start loading for any gun. There will be time to slowly work up to hotter, safe loads.
Any load deemed an Elmer Keith load is probably accurate at quite some distance, for a handgun.
Buying hardcast lead bullets may be something to consider. I use to get 500 bullets for less than $30.00 and they shot well at 100 yds. With the price of lead and copper now, buying in bulk could save some money and give you more practice with the gun.[/url]
Anyone who shoots a sabot bullet has had the problem with loading the next round with a dirty barrel we have all struggled with it.
Between muzzleloader shots I have done some research and testing on my own to find out what works for me for the next shot. I have been using a product called bore butter and when the muzzleloader is just sitting around I leave it caked in the barrel for protection. Have also found that if I lube my sabots with bore butter they really slide nicely down the barrel....
