Hey new guy here.. So I bought an Air Hawk for cheap, ordered a .22 cal barrel for it, put in a 2g Vortek kit, a Leapers scope. I shot it for about 100 shots with the stock .177 barrel, and couldn't get it to group. Installed the tune and the new barrel, and still no grouping.
Here's what I've done:
1) cleaned barrel, recrowned it and checked for burrs, pushed a pellet through smoothly.
2) fixed the yoke on the receiver where it bolts to the stock
3) checked for a leaking breech seal
4) tried every hold and benchrest combination imaginable with only negligible improvements
5) insured that the scope isn't creeping and even swapped another scope on

Here's the kicker: I have only shot Crosman premier hollow points, as that is all thats available locally. Can a pellet really cause inconsistencies this bad??? Now this thing will throw a 7" group at 15yds no matter how i hold or rest it. The pellets come through the push test with rifling on the skirts, and just a touch on the head. With no tight spots or snags. Is there anything I'm missing other than trying more pellets? I've shot 500 rounds through it with no change. It quit dieseling after about 50 shots. Thanks for any advice!

I would only use good quality German ammo try Superdomes , Hobbie's ,,and any you can get, until you get accuracy , if you don't,the gun may be the problem ,

Don't forget about JSB. Their level of quality is right there with H&N.

I ordered a pellet sampler last night to hopefully clear up my problem. Thanks for the suggestions guys. I bought the only other pellet available locally, Gamo Wadcutter Match, and they actually grouped a little better. But they look like crap up close so I expect improvement with a good pellet. I was just curious, how bad have you had a certain pellet shoot? Is it common for the "wrong" pellet to throw a group thats all over the paper? As in, covers the paper? Can one kind really shoot THAT bad? Sorry for the newb question..

It's not so much the make of pellet but the quality , gammo are a medium quality pellet , whereby you get different sized skirts/heads and a variance in weight from one pellet to the next , this is what causes the bad accuracy ,
you only have to look at German pellets and you can see the quality ,
I wold also give the barrel a good clean, then shoot about fifty of the good
pellets to put some lead back in the barrel ,
also check the crown ,
