I'm not sure yet. I might try fire lapping and see if that will help it. Or maybe reach out to professionals and see if they can recrown for me.

Taipan Gotta problem...
- Thread starter Dairyboy
- Start date
The OEM barrel that came in my Vet Long was excessively choked, even for a Veteran. It didn't have this burring right at the ends of the rifling though.
That barrel was fixed by aggressive polishing and fire-lapping. Since I didn't want to firelap the entire length, I did it this way.....Bare barrel (no shroud, no mod, nothing. Turn down the hammer tension to the point that pellets will just barely exit. I used some of the Seneca (Eun Jin) pellets with three essentially lube rings in the head of the pellet, thought being that those rings would help the abrasive stay between the head and rifling the longest. With gun decocked and no pellet in the breech I'd use a qtip to poke a bunch of 280grit Clover into the last inch of the barrel, at the muzzle. Then I'd shoot 5 or so shots, then repeat. Eventually it opened up the choke to the point that pellets measured groove to groove went from 0.211-0.212 (measurements before process) to 0.215-0.216 (measurements after process). And pellets pushed through with a rod still felt resistance, but not that absolute wall of constriction that was felt before the process.
As for results, it went from not keeping .22MRDs on an 8x11 sheet of paper @ 100yards, to keeping 95% of them under 1.75 @ that same distance. So I didn't make it an MOA shooter (I blame the pellets) but it did make it a usable barrel for hunting/plinking/pesting.

I must have missed it unless you mean the lapping thread. Haven't checked there yet. That is unfortunate and have heard of the tight choke but this one is literally just at the crown. The pellet stops right at the edge. I think a good recrown might work but also could fire lap also and see how it goes.

I was talking about the lapping thread. I just deleted my comment there since it's being discussed here too.

I can't say I've seen this before personally. I've had tight choked guns but the burs are shockingly not something I've had before even on cheap guns. And a bent shroud on top of it. Glad I got this gun for cheap. I chased my tail all day today where I'd get pretty decent groups then all falls apart. Noticed the wind seemed to really affect the pellets. Now I understand why

I did true both ends eventually and it shoots well now.
I second the carbon fiber tube idea if practical.

Messaged Motorhead and he said he can take care of it no problem so will ship the barrel to him to do the crown and work his magic on the rest of the barrel.

Yeah I can try, I've done many other things but at this point I want it done by a pro. Im good at less finesse stuff, being a farmer i can do many different things, but not with the attention to detail as one who specializes in these things. The barrel has shown great potential despite the issues so with it cleaned up and massaged by him I'd expect something great.

I get what you are saying but you know doing what @Joedirt199 said is super easy and it would be pretty difficult to mess up as the screws head self centers and improvement can be seen very early in the process. IOW it doesn't take much time or finesse.

I found that I have the stuff to do it. Figured I might as well try and if it doesn't work I'll send it out.

Wow , ive never seen a crown like that . Good thing you caught it and didn't lose your cool .

Make sure to rock the drill around in a circle so the head doesn't just sit in one place. Gives it a more even finish.

Lol I was losing my cool yesterday cause I thought the bent shroud was my only problem. And when I was still chasing my tail to figure it out yeah I was stressed. Figured I'd pull the barrel and see how a pellet felt. Once I found that I felt way better ironically cause then i know i wasnt crazy lol annoying yes but a fixable problem. As a Taipan fan for years I'm shocked and find it unacceptable that this gun was sold. If this was new I wouldn't stop until I got a full refund. But being used and at a great price so be it I'll make it work cause I know how great they can be.

Ok, it’s close to 8:30 here and 7:30 there. You’ve had plenty of time to get this project underway. Cough up some results with pictures.

Lol brother I've had it done awhile but had no time to come back and post. The excitement has been hard to keep in this longOk, it’s close to 8:30 here and 7:30 there. You’ve had plenty of time to get this project underway. Cough up some results with pictures.

So I just gotta say thanks to those who pushed me just to try it. I saved myself alot of time and some money, on top of learning a new skill that I thought would be too hard but ended up being stupid easy albeit time consuming. Anyways here's my before picture. 
Here's my after
Here's my "shot groups" yesterday
Here's they are today
Had some wind again today so can see the horizontal spread. Anyways first 2 groups I did 10 shots and could tell the barrel was "settling" after the crown job. These were the top left and middle. The top right and bottom row were 5 shots each of 18gr JTS. Then the E group is 5 with the 22.07gr JTS and the one above the m is 5 with the 21.53gr. I definitely need to visit these heavier pellets more as they seem to really like it. I'm amazed at what a crown job can do.
