Home Forums Reloading Varmint Rifles .220 Swift--anybody using Hunter

Swift is rough on barrels.

AA2700 has one of the lowest heat index's of any powder that will work well in the Swift.

I shot 44.5g of AA2700, Rem 9 1/2, 50g bullets at 4000 fps into tiny bug holes with Standard Deviation less than 10 fps!
You will see an improvement in barrel life using this AA2700. 2700 goes through a powder measure like water, as the flakes are tiny balls.

Many, many people are using AA2700 in the Swift as it works great from 50-55g bullets, fast and long barrel life.
