Home Forums Reloading Varmint Rifles Favorite powders/primers for the 220 Swift???

I've had good luck with IMR 4064, but now use H414 and 50 Hornady Vmax; 43 grains gives me 4050 fps and 4-shot half-inch groups out of Ruger 77 MK II sporter. Norma cases and CCI 200 primers.

T O M: Your post regarding 50 vs. 55 grain bullets in the Swift... I didn't think to mention it in my earlier post, but I've also found 50 grain bullets are generally more accurate than the 55s. In my experience, this has held true not only for the Swift, but most, perhaps all of my centerfire .22s starting with the .222 Rem. Certainly, of course, there will be some exceptions.

The late Bob Hagel also mentioned this in one of his books. I didn't really think much of it until I did some experimenting on my own.
