220 ackley improved powders?

[Veebaro]

Have a 220 swift ackley improved with a 26 inch 1 in 8 planned on using a 62 grain Barnes ttsx. I have h1000, h4831, h4350, superperformance, imr 4064 and imr 4350 at my disposal already. Lets hear some opinions. Any input is appreciated.

AA2700 and WW760 are what I'd start with.

Good shootin'. -Al

Rl16 is like a perfect match for the 220 AI. That mean that H4350 should be too.

I have a plane jane Sswift, that loves H1000. .With 55 and 60 gr pills. Hope that will help you. Tommy Mc

You can basically use .223 WSSM data. I believe your 220AI is larger than 22-250AI/.22 Creed and smaller than .223WSSM. I agree that H4350/H4831sc will be in the neighborhood for burn rate for lighter projectiles. A long barrel might be able to take advantage of powders like H1000, Retumbo and Re26.

Volumes in al's statement!!!

AA2700 has one of the coolest heat index of all powders made. AA2700 is what we have used in the 22/250 AI, 243 AI, and 6 Remington AI for a LONG time. Throat life was greatly extended, and Win 760 is our back up powder. CCI 250's reduced standard deviation down to low single digits.

I have a 23" Hart barrel, 22/243 AI 14T that I am shooting the 60g Sierra at 4000 fps, bug holes abound....AA2700 of course.

With that combo, I’d look long and hard at the 4350 burn range

 

[Veebaro]

Sounds like 760 or 4350 are the way to go i forgot I had a pound of 760 as well they are pretty close together on the burn rate chart. Figured I needed to burn up a barrel at least once. Thanks for the feedback.

7828 worked very well in mine with 65 gr. Sierra’s.

IIRC back in the day, IMR 3031 seemed to be the go to powder for the standard Swift.

3031 seemed to work with most anything. Had a 243 that loved the stuff. 35.5 gr under a Hornady 100 gr Interlock shot one hole at 100 all day in a factory Savage 110E

Got around to working a load up ended up running 44.4 grn of w760 with ttsx 55 gr boat tails rifle was a little finicky it ended up settling down to .75 moa for a 3 shot 100 yd group at 4150 fps plenty good enough out of a featherweight barrel. Thanks again for the input

Imr 4064 is another great powder to start with. In my .22-250 AI that was always the one to beat! Good luck and let us know how it goes.

Staball should work too.

Two years, lol we are on the same time frame with projects ;-).

Big over bores, have a 224 Clark. Just started working with it, looking more at 75-77 grain bullets. Figured a 220 or 223 WSSM should give me an idea of powders.
