I got to test my 220 Swift over the last two weeks and wanted to pass on the information. Rifle is a Stiller Tac 300 action, Jewell trigger, Rock Creek 28" barrel with 1/8 twist, Hart long range tactical laminated stock bedded in Devcon, with a Nightforce BR 8-32x56mm scope. I am using the 80gr Nosler Custom Competitions and CCI BR-2 primers.
*****These loads may not be safe in your gun it is for my exact specifications on chamber, COL, exact bullet, etc...!! Start low and slowly work you way up. I actually started at 36 grs and worked my way up slowly*****
AA3100 powder at the following charges:
38.5gr- 3100 fps
39.5gr - 3218 fps
40.5gr - 3340 fps
41.5gr - 3479 fps ***most accurate load and a deviation of 6 fps***
42.0gr - 3495 fps
Let me tell you the Stiller Tac 300 & 28" Rock Creek is shooting too!! Worst load shot about .75 MOA and best shot .18 MOA. I shot the best group I ever shot at 300 yards measuring .57"
Thanks again to 40x for the starting load information it was very helpful!!
Any anyone else shooting fast twist Swifts? What kind of loads are you using?
