I have the exact same rifle. Walmart special. Yes, it is quiet but its accuracy sucks, just sayin'. Word of advice, fork out the $$ for a PCP u will not be disappointed. As for my Gamo.... it now sits in the closet collecting not bones, but dust.

I will tell you what, I recently met up with a fellow airgunner I met on GTA forum who was having issues with his 22 cal M-Rod. We met so he could shoot my AT44. He brought along his Gamo CFX underlever springer. We were both able to consistently hit cans at 90 yards with it. I was pretty impressed with it's performance. I've had a couple of break barrels and decided they were not for me, so I moved to PCPs. I would get an underlever fixed barrel springer if I couldn't get a PCP.

At sixty yards I put down sub minute groups, from a wrest or free hand the free hand opens up a little at that range but not enough to closet lock my gamo, I've found its the scope that I get most issues from

Hi blackdiesel and Bullwhisper.Save me some time and frustration.What pellets were you using? The RWS Superdome 14.5 gr I have are good to about 30 metres but that is their limit I found.It's a CFR in .22 cal.

Pulcat So far crossmen hallow point 7.4 grains are the most accurate for me but I'm using a 177 springer or a 177 variable pump
but so far gold flights silent cats and crosmen premier hallow points are the best shooting for my rifle at rang from ten yards all the way to 60

I have the same exact rifle but I use a Hawke Optics one piece mount that works very well and costs much less than the BKL. I have found the best pellet is the JSB Diabolo 10.34 grain. I have hit squirrels out to 60 and 90 yards. Not pcp accuracy but not as bad as others say.

Bullwhisper · Nov 2, 2015

Thank you crane, this is input I'm looking for haha, the BKL I'm looking at is about 37 $ how much is the hawk you purchased? And I was going with the crosmen premiere dome 10.3 grain in bulk from pyramid air . Com also where I found the furniture I'm looking to put on my bull whisper (bc)

The chp's are good but the jsb pellets are bit better because of the uniformity of the pellets. If you can get a good tin of chp's where all the pellets fit the breech the same, your shots will remain consistent.

All the things the guys said above. Also, I had 2 bone collectors in my shop trying to find pellets they "like". Same guns, 2 different pellets. I suggest getting a pellet test kit and go to work.

Bullwhisper · Nov 4, 2015

Yeah that's what I've done with my 12 or so different pellets unfortunately there all Walmart brands (p.s it hats daisy pellets passed ten yards haha) it like the chp the most so far they have a really snug fit in the breech.

I would suggest staying away from a bipod. In my experience, any time I rest any of my springers on anything solid (like what you do when you rest it on a bipod), it changes my POI, requiring re-zeroing. Once re-zeroed for the "solid rest," the POI changes when I shoot it off hand.

If you gun shoots "hot" (fast, high velocity), definitely try some heavier pellets. CP 10.5s are a good bet, if you can get a good tin of them (which I haven't for awhile). I agree that the JSB 10.34s are a good bet as well. Have you tried H&N Field Target Trophies yet? Lately they seem to be my "sure thing" pellet in all my guns (.177 & .22). Very consistent fit, and good groups are waiting for you in those tins.

Bullwhisper · Nov 5, 2015

I was afraid of that with the bipod, I was thinking of a long one for a good sitting position, because I generally choose too wait out my intended query

I have used a Primo's Trigger Stick with some success (still working on my technique). I just set my hand in the cradle, then the rifle in my hand. Depending on your rifle and how hard it recoils, you may be able to set it in the cradle without your hand in between (mine came padded with soft, little rubber "fingers"). I think the Pimo's can still be had for around $80 on Amazon? If you don't need something that fancy, you could also just make a set of shooting sticks for very little money. There are plenty of YouTube vids that cover how to make them.

I recently outfitted two of these accessories
the mildot 3-9x35 scope and the bipod 5-10 and it's great from the bench I'm taking critters out two 70yards with crosmen premier hollow points 7.5 grain body shots and a few head shots, the poi drastically shifts from bipod to off hand so I just sight in for off hand if I'm in the woods, and leave it as is its dead on at 20 yards and a one dot hold at fifty a two dot hold at 70 haven't poked out further than that yet also my poi doesn't shift much with magnification the biggest difference is between 3 and 9 but out too fifty and 70 I use 6-9 anything closer gets 3-5 it's doing fairly good grouping at 70 I'll see if I can't put it on paper and post a picture
