Has a Krieger 1x7.7 Barrel, any advice on powders for 75-80gr bullets?

RL-25.... is a favorite in the fast twist, heavy bullet .224 area.....

From the lack of response I think maybe I ought to explain what a .220 Wilson Arrow is. It's basically a Swift, it has the shoulder pushed back, angle changed slightly which gives a longer neck, but basically it's a Swift.

Actually, the Arrow has both a longer neck and a longer case body so the capacity is not changed much, if any.
I've never had an Arrow but have shot a regular Swift with heavy bullets (a long time ago). I would try the slower powders like 4350, 4831, and even 1000. Preacher's suggestion of RL 25 is a good one. Even RL 22 would probably work.
Go to Steve's Pages. He gives load suggestions for the regular Swift with heavy bullets. The data is probably interchangeable.

I've got a 220AI with a 1-8 and use RL22 and RL25 for 75-80's, also have a 22-243 with a 1-8, same powders. You don't see many Wilson Arrows, how does it compare in performance to the 2 I listed? Is case forming a hassle, what action are you using on it?

The Arrow was designed by Wilson to get rid of the sloping shoulder. To be ornery, he also increased the body length and neck length so that his cartridge couldn't be used in a regular Swift. It's a simple matter to form the case in a FL die and fire-form it. However, you'll find many so-called Arrows that will take a standard 220 Swift factory round and safely fire them. Wilson used to chafe at such rifles saying that they weren't REAL Arrows. He was a mean old guy.
The capacity of a true Arrow is virtually the same as the 220 Swift. You'll also find several versions with different shoulder diameters all the way from the original .402" up to your AI.
