I'm looking for information on some good load data for this 220 Swift AI that I have put together. I've used a John Hart 27" heavy fluted barrel with a 1 in 9 twist. I've hooked it to a FN SPR action (Pre 64 Winchester Mod 70) and bedded it into a Richards Micro Fit Heavy Target Stock. I plan on using this for some target shooting and bench varmint hunting. As heavy as this project is I'm not carrying it around much. With some of the stuff I have put together in the past I'm thinking this animal is going to like 70 + or - a grain or 2 bullets. Does anyone have a good load data that may want to fess up? You can e-mail me at notahd@aol.com Subject 220 Ackley Loads Thank's guys.
