Hi,
I just got my 1st pumper, LE392 that has been steroided by Mac1. I have or have had numerous air rifles from Talon PCPs to springers and CO2 guns and mastered them all pretty quickly. I'm having a heck of a time getting this one to group and tried 3 different scopes on seperate mounts, 5 pellet types, multiple pump levels, and different resting locations. Way too many variables when you have to pump up for each shot. Can anybody give me any advice that can save my arms? My groups are consistently 2+ inches at 17 yds in my basement but it does put a couple shots out of every 5 in the same hole so it seems to have the potential, I'm just doing something wrong. Thanks everyone.
Steve

try gamo hunters,JSB exacts,rws superpoint,hobby,superdome.also kodiac/baracuda. The new benji's tend to have largish bores,look for big and soft pellets.

..even if it's an adjustable parallax scope, don't believe the little numbers on the adjustment. Set that rifle down lined up on any type of small mark, hands off, move your head around in the field of view. If the cross hairs dance off the mark, reguardless of what the scope claims, it's not right for that range.

For whatever reason, have had "problem child" pumpers that refused to get in line right away. Pumping them to 10 stroked, firing (even if you just shoot it into the dirt), cocking and firing again (to clear any residual air) and then trying for groups seemed to help when they were new...as they got worn in, the problems seemed to dissappear.

Can't swear every gun will shoot well at 6 pumps, but most do....others seem to show no differnce in grouping with 4, 5 or 6 pumps....but if pressed for a starting point, would go with 6 pumps.

is so use some Gunk Carb Cleaner and a Q-Tip and clean it out. It takes a few minutes but it is worth it.

If you do, remove it with paint remover, or brake fliud.
Then shoot some groups. I had the same problem with my
extended Steroid, regular Steroid and my L/E. I had good results with FTS's
in all the rifles at 5-6 pumps. 7-9 pumps in the Steroids shot JSB
Jumbos very well. Groups tightend up after cleaning out the paint.
As the saying goes, no pain, no gain. Welcome to pumpers.

Thanks for all the thoughful replies.
Ramjets, Kodiaks, Crow Mags, Daisy pointed, Benjamin, Crosman tried
Barrel is recrowned, no paint unless it's deep.
Parallax corrected and OK on 2 scopes.
It acts like a 52/48 type mag springer when you don't hold consistently, Is that an issue with pumpers?

... had horrible accuracy out to about 20 yards when I first got it; about 2" groups. After over 500 plus pellets through it, it's finally shooting great; groups under an inch now at that distance- which is a huge improvement from how it was shooting before. Someone responding to a previous post of mine stated that the gun simply needed to break in. I don't think anyone else that replied to that post agreed, including myself. Well, my LE has definately gotten better with more use! It isn't as accurate as one of those competition air rifles, but it's easy to successfully plink with at only 4 pumps. I really like having a scope since my eyesight isn't as good as it used to be. Shoot at least 500 pellets through it, then tell us how it's shoot'n.

Why the heck won't Crosman just manufacture all their Benjamin/Sheridan's with the dovetailed bolt housing?

BTW, JSB Predators and Gamo Match pellets shoot really good in mine.

They don't have recoil, so hold sensitivity shouldn't
be an issue. I think it's a pellet issue, try FTS's,
JSB's and CPL's. All these domes work well in my 2 Steroids
and L/E. Also, try all the diffrent pellets at lower pumps, 5-6.
My Steroids will spit out shot gun patterns with all pellets, 14 gr to
21 gr with more than 10 pumps. I don't even pump them more 8 pumps
now, plus it's a work out more than that.

<P>Hi Steve, </P>
<P><EM>Ramjets, Kodiaks, Crow Mags, Daisy pointed, Benjamin, Crosman tried....
Barrel is recrowned.</EM></P>
<P><EM>-----------------------------------</EM></P>
<P>    I've tried all of the above also and then some,</P>
<P>and seem to have the same problems that you have.</P>
<P>I have LE # 359 , it was modified by Skyler to </P>
<P>get more power with fewer pumps and 3 pumps</P>
<P>is plenty for backyard plinking and targets.</P>
<P>I bought a variety pellet pack from Straight Shooters</P>
<P>and found that the JSB exact Jumbo Express Pellets</P>
<P>give me the Best groupings with this gun. </P>
<P>I am also shooting at about 17 yards, </P>
<P>this gun goes about 490 fps at 3 pumps.</P>
<P>Beeman H&N Match pellets group well, </P>
<P>and the Plastic Nose Predators are about as</P>
<P>good as the Express pellets. </P>
<P>The problem is.... the Predators are a Bullseye</P>
<P>the Express is High and to the right.....</P>
<P>and the Match pellets are low of  point of aim, </P>
<P>with a flyaway now and then. </P>
<P>4 or 5 pumps changes everything, and </P>
<P>I'm about Scared to pump this thing past 6 pumps.</P>
<P>At 6 pumps I have had the Bolt to Blow back</P>
<P>on me a couple of times.</P>
<P>Guess I'll just spope it in on BullsEye with the Express</P>
<P>pellets , and use the Mil Dots to adjust for the others. </P>
<P>Crossman, ( any kind )  Daisy Match, and Ram Jet</P>
<P>pellets gave the worst results in this gun.  </P>
<P>One other Notable Good Mention, is the Stratton by JSB.</P>
<P>Keep Shootin' and let us know how it goes. </P>

into the bolt bore.Beeman spring gell is clear,so it looks better(less messy) than velo tar,which may be too stiff)The real fix is a spring loaded ball in the bolt like the old ben/sher guns had.
