Shooting my new HW77 today, I have to adjust the rear sight fully left to get close to bull? That was with 3 different pellets. JSB, HN Crossman

New HW77
- Thread starter Zut

Barrel could be bent. With the sight adjusted left does the center of the Buckhorn align with the the center of the dovetails? If it is maybe it something with the sights. Is the end that the front sight mounts to plum? If it was crooked it would cant the front sight and mess things up. If everything looks right the barrels likely bent or there's a wicked burr on the crown.
Here's a brand new Hw35E I just worked on. It came shooting almost 6" off to left at only ten yards.
You'll figure it out

Hi Ron,
Your up late tonight! The buckhorn is not centered on the dovetail. I can't see the front sight out of plumb. I will see if I can check that out. I put a scope on it and need to check it as well. I have on old Leupold VXII. You know, this is the third Weihrauch I have purchased and I had to bend the barrels on the first two. Can you bend a underlever barrel?

Congratulations on the new rifle! It is a great rifle and really easy shoot all day. The back of the HW77 is a screw on cap. It has to align perfectly from the factory to get the dovetails lined up. Mine was off by a little bit and the way they got the rear sight on the rifle was a big hammer! My factory rear sight was way off as a result. Check the dovetail joints for misalignment.

I had a hw did that . Out of the box the rear sight was way to the right . I thought thats odd.. well like you even with that it shot good left..
Ended up being hard crud like somthing in the barrel i like to call it jb weld like stuff , anyway after a mean hard scrubbing and soaking to break it up and brush it out to a real slick shiny barrel it then shot stright and true.. trar sight now in the center..lol my beman close to the same. Being "new" this had to be a factory goof or somthing. But it was bad.
Anyway that stuff clogged the rifling and deformed the pellets shot out of it and caused that on mine. Once i got the barrel satisfactory cleaned sloved that..
Thing is on mine was how the rear sight was already way right like it's was shot and whoever shot it tried to adjust it right to correct? Anyway that was the 2ed gun i got from P.A with a funny issue. Or there (hw) just got sloppy leaving stuff like that in a barrel to sell new. So id try some good solvent swab the barrel good and let the sobvent sit a hour or so scrub with brush , check for dirty with patch ,repeat. . No excuse for that stuff being in one.
Just to add that one was so bad i used a tight patch and plugged the muzzle and fill the barrel full of solvent and soke it overnight .. it was that bad .

Interesting, I cleaned the barrel before I shot it and it was filthy. I noticed it was slightly tighter at the muzzle when I pulled a patch thru. I'll clean it again.

Dovetail is aligned really well. Rear sight came off with just a little drag at the joint.

Same with this one I think. So the did you have to adjust the cocking lever after you centered the barrel? My lever is slightly off center to the opposite direction the barrel will need to go. Making the cocking lever further off center.

Well normal cleaning just dont cut that crud..
So i was just looking at this and look at aging and removal.. ill now bet that was what it was in there . A cosmoline used that just got rock hard in side the barrel..

Thats pretty close to the issue... It was mean for sure.
After w good soaking of solvent i resorted to this with a push me pull me string to scrub back and forth ( not a recommendation). ..unless you find some copper or brass wool... No one around here had that or a .17 cal brush so thats all i had to make it a go ...
P.s... if you decide to get rid of that 77 at a super low bargain basement near for free price please let me know...

The tight spot at the end is normal. That's a choke. It's supposed to be there.
It's been a while since I straightened out my 97. I don't remember having a do anything with the cocking lever. There was enough play in the cocking linkage to accommodate the adjustment. It takes only the tiniest bit of bending to make big changes in POI. Proceed with caution.
Also during this process I'd hold off on the Crosman pellets as their harder lead can build up in the barrel and cause premature fouling. It can also affect the POI, accuracy and velocity of softer lead pellets. I'd say if you are going to use the Crosman, stay with the Crosman and make the adjustments using them.

The underlever barrels actually "adjust" with less force needed than the breakbarrels I've found. Yours should be a breeze with that loooonnngggg barrel.
One thing to check before you go any further: Remove the stock and inspect the welds that hold the barrel block into the main receiver tube. Grab the barrel and yank it around while watching those welds for cracks. I bought a 77K years ago for dirt cheap said to have a bent barrel. These spot welds had broken and the whole end plug with the barrel was moving. A quick grind and fill with the TIG welder and I was back in business. If yours is busted, send it back for a new one.

It doesn't take much. If you have a long enough straight edge, lay it down on the stock next to the action and see if the air gap is the same at the barrel end. I straighten barrels all the time. Most of the time the offending bend isn't detectable by eye but enough to cause problems

I wouldn't bend anything yet. New guns can take a while to settle down. The gun as a whole has to break in first. I've had loose piston seals and dieseling throw off POI considerably. Get a couple of tins of good soft lead pellets through it first before thinking about bending anything. That's if you can't positively verify bend with a straight edge

IF i got a rifle that was not right i would send it back . supposedly AOA test fires every gun b4 they send it out ?
