- For some reason the SC2 would not shoot this round at all. I thought it was the bullet, but it
shot the corbon 139 just fine.
- Uses Remington brass
- Very good standard deviation and extreme spread
- Fairly hot load, should provide excellent long range ballistics
- A large lot of ammo was custom loaded for GA Precision, but continued availability is questionable.

- 4" longer barrel gains 102 fps over the SC2 22"
- Ammo shot much better out of the KMW than the SC2
- At over 2800fps, the ballistics at 1000y is as good as the 300 Win Mag 190gr Match
- Very nice long range load
|
NOTE: "Accuracy with flyers" includes the raw averages including groups where the shooter
called a bad shot before rechecking the placement of that shot. The "average without flyers" is the average
group size with those "flyer" groups not added in.
