When I looked at the load info for the
22-250 with 55 grain bullets the velocity they are quoting is very impressive. They state 3887 fps, wow!

And that was out of a 24"bbl . So I ordered a few bottles thinking its gonna catch on.

Unfortunately they haven't included load data for the 220 Swift at this stage. It might be just the ticket in your Winchester 1885.

6 CM, 24" 1:8", 105gr bullet, 43.7gr Staball 3156fps.
In my 6 CM, 24" 1:7.5" , 105 Hyb, 43.0 H4350 gets me 3101, and 44.0 H4350 gets me 3200. Pretty comparable. I don't see 30-200fps faster with that data.

Thanks for posting up your load of H4350. However, that's not really apples to apples. Your load is over the recommended charge and your comparing to one that at a lower comparable charge. If you can go over recommended in your rifle the new powder would likely be a bit faster.
This is the Hogdon data for the 6mm Creedmoor and 105. Not the Berger and not that rifle but should be somewhat combarable. Those H4350 loads would track pretty consistent to this data.

I think you're comparing tested loads to a loading table in a manual. This guy's rifle might also digest a heavier load of the new powder, just like it does the H-4350 load. Maybe it would be faster than 4350; maybe it wouldn't. Need to try it to find out.
Hence the not apples to apples reference. If lancetkenyonʻs rifle will take a charge of H4350 that is 1.6gr over published data safely it likely would take a similarly larger charge of Staball. Not a Fair comparison to judge from.
Johnny's reloading bench did a temp test. Check it out. Still not good enough for me to switch from H4350
I got 2lbs on the way for a go in 6mm Creed and 25 Creed.

Thanks for the chart. Very helpful for general comparisons.
BUT... I'd like to load StaBALL 6.5 for my 6.5 PRC. I feel it would be very compatible with that cartridge.
NO??

NO its to fast for the 6.5 PRC ,its close to H4350 . 6.5 PRC needs the slow burners for top performance .
