I have a Crosman storm XT that came with a 3-9 scope. I'm having a heck of a time sighting it in. It's throwing lead everywhere. It goes high right then it'll drop low left. I tried using crosman match pellets and then crosman pointed hunting pellets and they're both the same results. Any suggestions?

is the scope and base tight?

Go through and make sure all the screws are tight then maybe try a different brand of pellets.
I had one that I was having a tough time getting to group and I switched to some Beeman pellets and I am finally getting good groups.
It could be the scope by some odd chance also.
Does it have open sites too? If so you might take the scope off and see if you can get some good groups with open sites if so your scope might be the culprit.
Just some thoughts. Hope you get it figured out.

what would be a good way to build a trap so I can get it down in the basement to sight in

I recently purchased the Storm xt and it did the same,Straightened out after a couple of hundred rounds.The scope is really clear-Much better than I expected.As far as a trap-probably build one out of 2x12s or something-Not sure that shooting a 1000 fps gun inside is a good idea though.On the pellets-They matter-the flat face ones are hard to load and dont offer the accuracy,Stay with the pointed-Like the regular crossmans.

Try JBS Diablo Exact pellets. They are a little pricey, but they are probably the most accurate around.

Also, you can stop pellets with a bag full of newspaper. I pack a grocery bag with my onld newspapers and then slide it into a wine carton to give me a nice flat surface to tape my targets on.

But, you need to be sure of hitting the target before you try doing that in the house.

What range are you shooting at to sight-in?

And, how are you holding the gun?

probably close to 20 yards. i was sitting with the rifle laying on a fence and i had it pinned against a post

Maybe your problem is that the rest you are using is too hard. Spring air guns have a lot of vibrations that can shake the barrel while the pellet is still in the bore if the gun is rested on a hard surface.

I'm no expert, since I just started shooting a second-hand RWS 48. But I have read and was told by the RWS tech on the phone to use the softest rest possible. The RWS tech says he uses a pile of quilts, sets the rifle on the pile so that it points exactly at the bullseye without him holding it, then gently slides into place and holds the gun very lightly.

I have been shooting from a bench, using an adjustable bench rest cradle with a sandbag. The RWS tech thought the sandbag was about as hard as I might be able to get away with, and I am thinking about making some other sort of soft supporting surface for the cradle.

What I have been doing is balancing the rifle on the sand bag and positioning it with the cross-hairs centered on the bullseye, then gently gripping it and firing the shot. (If I held my .270 that way, it would demolish my shoulder.)

I have been able to consistently make single-hole groups that are about 2 pellet widths at 50' (17 yards) using the Diablo Exact and Kodiak pellets, but no so good with Crow Magnums, Super Domes, or several flat-nosed "target" types. Beyond about 50' my groups expand more than proportionally with the range increase. I am still not sure that my barrel is not fouled, so I may be able to get better groups from other pellets as I pursue my refurbishment program for this second-hand gun.

If you have already tightened the stock screws and scope mount screws without improving your groups, then I think you need to get some better pellets and work on your grip. Also, possibly move your target in to 50' or less. As you found already, you can't sight-in until you an make a good tight group.

I had the same problem right out of the box, but it was operator error. The first hundred rounds were very erratic. Then, I thought to myself, why didn't I mount the scope like I would on one of my big game rifles?
The answer was Loc Tite 242 medium thread sealer. After re-mounting and coating all threads with the Loc Tite it is a totally different gun. It went from all over to shooting 3/4" groups instantly. I fired 200 rounds that day and the gun held true, given the wind and me pulling a few shots.
I hope this could help with your problem. One reminder, allow one full day for the Loc Tite to cure for maximum holding power, and tighten all screws as much as possible. Like I said, I bought the gun yesterday and was dissapointed. After 200 rounds today, I'm totally stoked and look forward to shooting more.
