The why is first.
some funky groups always with this 24" barrel gun and this funny looking uneven pattern at the muzzle end. Like the muzzle was flared in a certain spot no bullet wear marks.
notice the pattern difference ..the next pic is a 180 turn of the barrel.
This is why i wanted to have the barrel cut..and to see if there is an accuracy improvement with a shorter barrel.
Now the how..
Insert some cleaning patches into the bore below the cut you will make.
Mark the barrel around the circumference where the cut will be...
Cut just in front of that mark, I cut with a hacksaw and 32 tooth per inch blade.
I cut a little and rotated the gun a little and cut some more basically cutting around the gun ..Usually if you try to cut straight through with a hacksaw it will walk and you will end up with a curved cut.
The reference line was left so i can gauge where i am at as i file the fresh cut muzzle.
I used a single cut fine file to file it.
I used a flat smooth sharpening stone and some spit( you can use oil etc) on it to polish it flatter.
I need to chamfer the hole so i take some fine lapping compound and a marble in my fingers and rotate it back and forth.
After a couple minutes i clean that off and use dampened baking soda and polish the chamfer again with a marble.
I actually can see my cleaning patches in the barrel they are about 1/4" from the end and i fill this area with the damp baking soda.. as it is tough to keep enough baking soda on a marble to do any good.
Here is a pic of the finished product..
Some scratches are still there but the business part works well.
I may later add a large bevel to the outside.
I slightly chamfered the outside of the barrel with 400 grit sandpaper just to reduce the sharp fresh cut edge.
In no way am i condoning you cutting your own barrel..If you screw it up it is on you..
I felt my barrel needed something done to it as it was flawed.
And i chose 20.5" because if i screwed it up a smith could take it to 20".
But so far i am happy.
