Barrel Bending

[remuse]

Several weeks ago I posted about shooting 18" low at 20 yds with my Pedersoli .62 trade gun. The general rec was to bend the barrel with several methods offered. Today I did it successfully by golly!

Initially I tried to figure a method to measure the movement but gave up on it. The amount of bend for this purpose is just too small.

It's spooky but I pulled the barrel, placed 2x4 blocks under each end and stood in the middle with a bounce or two. The first attempt brought me to 3 or 4 inches low and right. 2 more plus rolling it on it's side once to correct the windage brought me to nearly dead on at 30 yds. Having an octogon to round barrel makes this process easy since it's stable on the blocks.

That's great Weston. There's nothing more satisfying than success.

Thanks for the report back.

Be interesting to know if "metal memory" gradually creeps back in to some degree.

Seeing posts like this from time to time, I always wonder why it's even necessary...ie: are the barrels not properly aligned when they finish production, or do they accidentally get bent after they've been manufactured, etc...with the simple laser devices available for this purpose you'd think it would be a final step of manufacturing

And then there is shipping. flinch

:thumbsup: That's the way it's done!

In this case, I'm not the first owner so I'm really inclined to think that it has more to do with individual fit than it does original manufacturing sin. With this gun, the front sight is so low as to have no vertical adjustment possible and there is no rear sight. Absent either a front or rear sight that can be adjusted that leaves the barrel as the only way to move things around. Now that it's been "custom fit", my guess is that the next person might pick this up and find it as impossible to shoot as I did initially.

Dixie gun works used to sell barrels that were bored off center, they told you up front that the muzzle was bored in the middle, but the breech was not correct. there is no way one of them could shoot where it was aimed.

Good for you! :thumbsup: Thanks for posting your successful results... it's encouraged me to be daring and try this with one of my smoothies.

For elevation if building a gun with a flare at the muzzle one can often save a lot of headache by trying the sight at differeent distances from the muzzle before attatching, one may be able to adjust for proper elevation this way

I don't know bout you, you're just too practical, you may just have too much common sense. Nuff said, I love your practical approcach to problem and it's swift resolution. KEEP IT UP
