I've been shooting a USAK for 3 years now.

It's a nice gun! I've thought about upgrading several times, but have never been able to see the need to when this gun continues to out-shoot everything in the gun cabinet. With the right load, my Knight will give me 1" groups out to 75yds (often times 100yds), first time, everytime.

I fact, I just used it last month to win a "Postal match" over some high dollar, center-fire equipment.

I have the #11 cap model and have found that using moderate powder loads and heavy bullets (300gr & up) is the best bet for accuracy. And so far, I've NEVER had an animal stand back up after being hit by my load combinations.
