Re: 220 swift whats a good off the shelf brand and what grain
It doesn't do you much good if you have already bought, but the 220 Swift has never been a good caliber for factory shooters. I own two, and neither has ever seen anything but handloads.
If you have not bought yet, I'd suggest that you think about a 22-250, instead. That cartridge does seem to have a beter selection of loaded ammunition.
Best advice is to get into handloading right away; you will never be sorry. You also will probably never "save money" handloading, but you will be a more intelligent shooter.
Good luck, LB
