I just picked up my third airgun, and first in .22 cal. It's the Hatsan 95 Vortek QE in .22 caliber. So far, I've put very close to 400 pellets through the bore and I think things are looking promising for this rifle. I have a Hawke Airmax EV 4-12X AO scope ordered that is supposed to arrive tomorrow. Once I have the scope mounted and sighted in, I'll start trying different pellets to see which one(s) this rifle may prefer. After contacting Hatsan USA about the rate of twist, they replied that this rifle has a 1:17.7" (1:450mm) rate of twist. If you own one of these rifles and have found that "magic" pellet that it likes, please share. At least that'll give me a starting point. Happy shooting.
