Backboring refers to a process where a shotgun barrel is reamed out to remove excessive pitting. Watch along as Larry Potterfield, Founder and CEO of MidwayUSA, walks through this interesting process using a set of reamers, a T-handle, and a set of Parker shotgun barrels.

What does backboring in this fashion do to the chokes? It seems it would take a full choke and reduce it to a cylinder choke. What am I missing

@ericgross6932 7 лет назад

John Miller You simply stop the back bore operation as the reem contacts the choke constriction.

@Akhazmat907 6 лет назад

John Miller this is for smooth barrel shotguns

@gunsmith549 6 лет назад

Choke is removed if you exit the muzzle. It's not that hard to ream for threaded or fixed chokes.

In a previous video of yours, you backbore another shotgun using a jig which makes use of polishing stones (RU-vid video: "Gunsmithing - Repairing Pitting in a Shotgun Barrel"). What are the advantages/disadvantages of using a series of metal reamers to backbore barrels as opposed to a jig with polishing stones?

@gunsmith549 6 лет назад

Deep pits are not removed by polishing, Back boring gives a reliable bore diameter from start to finish. Polishing a bore helps reduce wad fouling and improve consistency between shots and in the field

@markcooper9063 2 года назад

You can remove some pits with the stone in a fixture I have one you can remove pits with a series of stone .002 or .003 after the pits are removed you polish with a fine 400 stone

how does Pitting in a barrel occur? Is it due to rust, wrong munition?

@nathan47911 8 лет назад

+elitex2211 Rust. modern munitions are noncorrosive, however if the powder residue is left for extended periods it does cause problems.

@gunsmith549 6 лет назад

Yes, rust and that could come in some cases from improper cleaning after black powder, Or corrosive power and or primers in some case.

That's a lot of metal to remove from very old Damascus barrels, if you plan to relay that separated rib and use the gun.

@abiel.rodriguez 6 лет назад

So barrell inner diameters are larger..what now? Sleeves?

@gunsmith549 6 лет назад

No, the larger bore diameter will help patterns actually.

Só queria que os vídeos dele tivessem legendas em português

@Wolfwarrior2007 9 лет назад

hey I am curious why you don't show videos of smithing on semi auto firearms

@LandersWorkshop 8 лет назад

+Wolfwarrior2007 Because that's the way it is.

@@LandersWorkshop That's right, the cost of replacing the mass produced parts of a semi auto firearm vs. a gunsmith's cost of working on a firearm doesn't justify the expense of the gunsmith. Old double guns are different. You can't just find new barrels or parts a qualified gunsmith will have to make or renew the gun that you have. Hope this makes sense!
