Where does your bent rifle shoot? Way off from what the sights allow? If you can sight it in it doesn't really matter if the bore is straight or not.
There is only one fly in that ointment.
The rifle will only shoot to point of aim at specific distances.
I've tried this on several rifles with bent barrels. Of course, it depends on how bad the bend is. A slight bend may hardly be noticeable out to 100 yards but will definitely drift where the bend deflects as distance increases.
I had a 338-06 fitted with a take off barrel. No, I didn't do the work, it came in a trade. That rifle would shoot to point of aim at the distance it was sighted in for with moa groups.
When the distance was increased from 100 yards to 300 yards, the group was 8 inches off point of aim at 2 o'clock high. It increased that POI as ranges extended.
I tried several things, such as load development, bedding, re mounting scope bases, rings and exchanging scopes before doing what I should have done in the first place, check the barrel for straightness.
There was a barely detectable offset in the rings as your good pics show.
The only thing I can assume is the barrel was over heated when it was being profiled. Very difficult to see.
I went to a friend with the rifle and showed him the issue. We pulled the barrel and chucked it up in his lathe and set up a dial indicating plunger micrometer to see if we could measure the bend at its central point and of course to find that point. If memory serves, it was around .008 inches. Not much but enough to give issues.
We marked the top dead center of the bend and took it to a hydraulic press, where we applied force to bend it back. Then back to the lathe. NADA. The bend hadn't changed at all.
Back to the press, more force, but instead of pressing it to zero, we pressed it beyond zero to the same amount as the bend. Then back to the lathe. It worked, but not quite enough and we had to repeat the process a couple of times until we were satisfied. It came out very close to zero.
Barrel steel is flexible.
That rifle shot acceptably out to 400 yards, where I quit testing it. It consistently shot under 1.5 moa to that distance with hand loads. No matter how hard we tried, that was the best it would do with the loads it liked. That rifle is still shooting Elk and Moose on a regular basis in Ft St John region. It gets less than 50 rounds per year shot through it and its present owner says he hasn't done anything but clean it and make sure its shooting to point of aim out to the distances he's comfortable shooting.
Here's the caveat to getting a barrel straightened. It can get expensive if there is a lot of shipping involved and the gunsmith is on a learning curve. I'm sure guntech has the necessary experience to do the work.
Whether he's still willing to do this sort of work????
Then, there is another problem that might occur. IF the shooter is one of those that likes to shoot without allowing the barrel to cool after 2-3 shots, the heat created may cause the bend to appear again. Whether it will go away after cooling is the question. I've never seen this happen but have heard from people I trust this does happen.
