I started looking for another OCW for my swift using a different powder

I used varget earlier this year and now these tests are with H-380

My swift heats up so quickly I can run 10 rounds through and then I need to let it cool off!

Anyone else have a favorite powder for 220?
Test (100 yards)
Hornday 55 grain varminter
H-380
39.0 grains 5 rounds
39.3 grains 5 rounds.

I don't have a swift but have a couple of friends that do. One friend had about 600 Hornady Frontier once fired brass so I made some rounds for them.

34.3 gn Varget under 55gn Hornady SP/C with FLR primer at 2.655" COL.

Both are getting .5MOA at 100 yds.

Wanted to buy a swift for myself but settled for a 22-250. Ballistics are basically the same and I am very satisfied with it. Not sure what I am going to do with all the brass from the swift.
