1Kyd30, my 220 Swift shoots in the .1's and .2's all day long. My best three shot group, at 100 yards, is currently .173, keep in mind this is custom built Swift shot with quality loaded ammo by yours truely. I shot this group with a 40grn V-MAX, with a muzzle velocity of 4350fps. Here are the specs if you are interested:
1. Remington SS Action, sleeved w/a Speedy Gonzales Sleeve
2. Lilja 28" 1.250 tappered to .920 at muzzle.
3. Holland Muzzle Brake
4. McMillan A-4
w/Adj Cheek piece and ADJ LOP
5. Jewell 2oz Trigger
6. Kelby 30mm Rings
7. Nightforce 5.5x22x56mm NXS
This rifle is my dedicated 300 to 500 yard varmint rig. My friend has a regular 22-250, and after he shot and saw the performance of my Swift, he is having a 220 Swift built as we speak. Trust me, if you go with the Swift, you will not regret it . If you want some load data, let me know.
