Help Support Modern Muzzleloading Forum:
I would have to suggest H4895 with the 50 to 60 gr bullet weights. If you shoot hornady i would try a 55gr v-max and start with 32gr and work up to 34.8 as a max. Varget is another popular powder used with the 220. Hope this helps

Swift? That can't be any good! Its over 70 years old! I really, really like the Swif!
I have messed with several Swifts over the years. I4064 is a good choice with lots of data available. The 4895's also work well. I have used both for lots of good loads.
I believe it was Ted Curtis of Accurate Powders that suggested 4350 as a better choice. As I remember he said with 55 grain and heavier bullets, the 4350 gave better velocity while maintaining good accuracy. I did get good accuracy and speed, but it was hard to get a max charge in the case (powder just too bulky). I next tried H414 (some call it the ball version of 4350). I haven't used another powder since.
I'd start 10% below a max charge of H414, a mag primer and 55 grain V-max bullets. Increase the charge as prudent. Every Swift I've worked with did best at the top end of loads. Every Swift I've tuned has been sensative to bullet seating depth. Ideal conditions would be for the bullet to just be shy of the lands. However, I've not seen a factory chambered Swift where that will work for most bullets. If your gun is a quick twist (1 in 10" or quicker), you might have good results with the heavy 65-75 grain bullets. For the shorter bullets (50-55 grain), I will develop a working load with the bullet seated out as far as practical. Most often the overall length is restricted by magazine length or having the bullet in the case. Next, I'll tune the seating depth by seating bullets deeper in 0.010" steps and finding what length does best.

The weights listed are for bullets, not powder charges; right?
Good reference:
