Everyone knows that!

Krag rifling twist-rate is one turn in 10 inches. This rate was carried over to later U.S. .30 cal. military arms.

A projectile makes almost three complete rotations on its trip through a 30 inch Krag barrel. (You would have to subtract the length of the chamber & throat).

I just got the email I was looking for on the barrel rifeling condition.
Report being very little rifeling left.

So my question being is can these be rebored.
My impression is that they have miniumal land/grooves.
So there is rifeling there.
Thanks

MiHeadShot... where in ole Gander-Land are you located?  If you're close to this area... it might be prudent for Butlersrangers and I to meet you at the range!  Chuck and I sometimes meet at Island Lake, which is part of the Kensington Metro Park area near Brighton.  As far as I know... they haven't shut down shooting ranges yet in all of this Covid craziness!

psteinmayer: Hey Gander boy,lol I'm in Da Yoop at the moment, hoping to become a troll again soon.

These 2 barrels i'm looking at on an auction is what i need to know about.
I don't mind having them rebored if I can get them ast as good of a price as I think I can.

Both have the reciever triggers and bolts

If you are wanting a real project to work on, I could see the trouble and expense of re-boring.

You could also save your money spent on new barrels and re-boring and everything else and buy a nice Krag ready to shoot!

Good luck, though. Keep us informed.

That would be one way, but I might be able to get these 2 units for under $100.00.
So as you say I can get them rebored, or put new barrels on.
Need to find out those costs, but i'm a wood worker and have stock material in my shop.

Where in Da U.P., eh!

BTW - A complete Krag action and barrel for under $100 is a 'no brainer'.

It is amazing how well even worn Krag barrels often shoot.

butlersrangers: I'm in the central part of Da Yoop in Iron County by Crystal falls.

Yep I figure just looking at parts that these two units would be worth trying to get.

sellers Discription says fair land & Grooves.
Don't know the cost of reboring (checking on that yet, but new Criterion barrels are $285. ea. and I can't buy a complete Krag for that.
Should know more in a few days.

Do you or anyone else know of someone who does rifle boring???

My parents were from the Copper Country (Calumet), but, I was born a Troll.

I don't have leads on re-boring. It's an expensive process and ends with a .35 cal. 'Wild Cat' in the 40,000 psi, or below category.

Any 'buggered up' or 'cut-down' military Krag stock would allow testing a complete barreled-action for accuracy.
It's amazing the interchangeability of Springfield Armory stocks, within a model  group.
(The model 1896 and model 1898 stocks are different in the bolt handle recess area).

With the U.S. Krag, always use a barrel-band or barrel anchor-screw, to keep the barrel secure in its channel.

The Krag trigger-guard/action screws are close together.
Uncontrolled barrel whip will split a stock, horizontally, behind and in front of the magazine area.

I was born, raised and spent all of my life (save for my 13 years in the service of our great US Naval Institution) as a troll.  I've spent exactly 2 weeks in da Yoop - a family trip to Copper Harbor when I was 13!  I'd LOVE to go back though...

As Chuck said, even well worn Krag barrels can achieve amazing accuracy.  Some guys shoot cast out of their shot out "Tack Drivers!"  Also, after slugging the barrel, you might find that shooting oversize - .310 or bigger may garner excellent results!  I'm no expert, but I would consider re-boring an absolute last resort.

How come y'all make shooting left-handed ("...and he shoots left-handed") sound like a bad thing? Th'ain't nothing "wrong" about shooting south-paw. It is what it is.
