Barrel bending?

So this evening I thought I would do a bit of basement paper punching. Nothing special just 10 yards in the basement like usual, except tonight I failed myself.
As I was breaking my R9 to load another pellet the barrel slipped from my fingers. I was mid stroke and the barrel snapped back probably 70-90 degrees. I immediately knew that this could be bad, so I cocked and loaded like normal and my poi had shifted 1.5 inches at 10 yards upward. I went on to shoot 4 more 5-shot groupings and my suspicion was confirmed.

Previously it it had been right on dead accurate at that distance, but now I fear it might be less consistent, and that if I try to adjust the scope that it might top out the elevation adjustment and damage the scope.

Im so disappointed in myself and fear that some action is necessary. And after a search for how to bend barrels I've concluded that there isn't much out there.

Has this happened to anybody else? Have you fixed the poi shift? Or do I need a new breech/barrel combo? 

This does afford me the opportunity to attempt something another user has said and order a HW80 breech/barrel and put a moderator on the gun. But again I've done some looking and I'm not sure how much audible difference a moderator would make to this springer or how it would affect consistency and accuracy and so in and so forth. 

Right now im curious if;
-I should attempt the droop the barrel?
-I should send the gun away to straighten the barrel?
-I should order a new barrel?
-I should order a threaded barrel and have a huggett mounted?
-I should take a barrel droop compensation mount and put it on backwards? 

Your input is welcomed, thanks
 
If your comfortable with it. bend it. Not for your reason but I have bent/straightened.drooped/whatever several springer's.
If you are NOT comfortable that you can do this ( it take little pressure and in my opinion some tools but folks do use a fork in a tree sometimes) just have a pro do it, shouldn't cost much.

Do look for other damage.

Spysir is correct. Also there is a lot of inexperienced advice in that other thread. Just bend it back. When I have had to do this, I used hardwood blocks in a large vice at three points. Support the barrel at two points on either side of the bend and use a third block on the high side of the bend to apply pressure to the bend. Tighten slowly and take it to the point where you think you have it straightened out plus a little. Pull it from the vise and take it to the bench and shoot it to check. After enough trips to the vice, tightening it just a little more each time, you are going to finally get enough courage up to apply the correct amount of pressure. You are going to think that you have bent it too far and then when you shoot it you will have done your job. You can also make a jig using a couple of hardwood V-blocks mounted to a stiff backing like a 2x4. That jig and a large C-clamp can give you enough leverage to bend your barrel. Either way take your time and don't bend it too far in the other direction by getting in a rush. I've got one rifle that the barrel is so true to the mount that it is essentially zeroed at 25 yards when the scope is set to mechanical centers.

I was struggling with my Crosman Nitro Venom Dusk 22 recently. My rotator cuff in my left shoulder was really giving me fits for a while, I should have never tried to sit and shoot that day. I got the barrel half way cocked, my shoulder shot pain thru my hand and my grip opened up. Barrel just about slapped me in the face, next shot, 6 inches high at 20 yards. I knew what had happened, I just removed my scope, called Crosman, ordered a barrel......It happens, easy fix. I switched to a 177 barrel, I just really like the faster velocity with the 177, with heavy 177 pellets.

Well I took a lot of advice most of you all and bought a c clamp to bend the barrel back so that my poi was about where it was before. 

Perhaps it was my lack of confidence, or perhaps not but my 10 shot groups were slightly larger with certain pellets and smaller with others. 

Perhaps I am being hyper sensitive but now the gun's report is louder and it smells different after a shot, almost like it's dieseling. I can't explain that.

I compared my previous groupings to decide which pellet to use for the initial bending. Then after it was back where I wanted I did a 6 pellet panel to see how the other pellets worked post bending. I'll post pictures if anybody is interested in seeing how bad my handwriting is.

Sometimes you get lucky. You got really lucky you didn't get slapped in the face. That could have cost you a trip to the hospital.

That's an easy fix. It is most likely bent a little where it enters the breech block, and not along it's length. You can easily confirm this by using a long straight edge against the barrel. I've straighted many for customers who did the same thing. Put the breech block in the padded vise and pull on the barrel. Keep checking after each attempt. You're lucky you didn't crack the stock at the pistol grip. I've repaired a few of those for people as well. Call me if you need more details. Scott 603 903 5368.

Barrel bending is common with me. Whenever I get a new scope or mount I bend my .177 R9 or .177 HW95 barrel so the point of impact is within about 1" or less from the aim point at 30 yards then do the "fine adjusting" with the scope turrets.

If bending the barrel upstairs for a poi of about 1/2" from the aim point at 18 yards I use my home made barrel tweaking gizmo like this.........





Works a treat and this allows me to always shoot with the scope reticle near optical center.

By the way, barrel bending is part of barrel manufacturing to make the bore straight.........


Here are a few 50 yard groups shot sitting on a bucket and resting the gun on cross sticks with my "bent barrel .177 HW95" so it doesn't seem that the barrel bending affected the accuracy in a negative manner..........
