I have a Krag with an Over sized bore.

[Bfh_auto]

I tried shooting 308 diameter bullets in it and got horrendous accuracy.
So I started to clean it. The cleaning rod falls through with a 30 cal brush on it.
Do you think this is a good candidate for paper patch. Or should I go to running .311 or .312 jacketed depending on what it slugs at.

Slugging is a good idea. I strongly recommend measuring and comparing your fired brass with an unfired round. People did occasionally rebarrel/bore out these guns.

Could pony up and have it sleeved/relined or a new Criterion barrel as well, if all else fails.

I did see the Criterion barrels the other day.
If I did anything. I would like a 35-40 Krag with a .357 bore.

The brass looks the same as my other Krag. The bore is smaller than a 32 Winchester.

 

[DocRock]

So, not a 35 Krag. Slug it and see what you have. May be that .303 Brit bullets will serve.

If not,and especially if the grooves are extremely shallow, you may want to send it out to Jesse Occumpaugh (JES Rebore) to be made a 35Krag (just the .30 Army necked out to .358). It's a great cartridge.

I fired a 30-30 once, bought it from cabelas. Thought i had looked it over pretty good. Upon shooting, I noticed the brass were fire-formed into 30 Ackley Improved. The brass that exited had a much sharper shoulder and greater case capacity than the 30,30 shells that went in.
It was rebored to this new improved version at some point. Just about soiled my undies, as at the time i did not know that fire-forming 30-30 in the 30 Ackley improved was actually safe. I thought i had done something really dangerous.

Got irritated, and tried to take the gun back to cabelas, which they refused. It was beyond the 30 day receipt, but i tried claiming they advertised a 30-30 but it clearly no longer was a 30-30. They refused, they didnt care (a guy on the phone from the gun library) i didnt pursue any further. Should i try again with the higher ups at cabelas?.?

Yes.

The .35-40 Krag had a strong cult following way back when:

In older guns it's common to slug the bore and find it larger than current spec bullets. That's where casting comes in. The 303 and the 7.7 and a few others are well know for being like this.

I would just buy 30-30 AI dies. It's an interesting cartridge.

Thinking about it.

that’s what I would do as well, pretty cool if you ask me

I think they packaged the bore brush wrong.
My bore slugged .3085 and .3050.
I'm going to try some loads now that it's cleaner.

Good to hear. Undersized bore brushes are a pain. My Krag barrel was like a pipe. No rifling at all. I put a replacement barrel on it and it's much better now.

It looks like a see pipe for sure. I'm still going to try some bullets before spending $300.

 

[dh1633pm]

It cost me about that much. Got the barrel on ebay and it was nice. Mine is the NRA cutdown with the 1903 front sight. Replaced the barrel with the same. New barrel had all the parts already installed so it was an easy replacement.

Try some floaming bore cleaner to get any old copper deposits out then run a some patches. Stick with flat based 180 grain bullets and you will probably be happy!

There is not copper in there now. I cycled clr, and copper solvent. Then I run some abrasive compound to smooth the rough patches.
I do have 180 round nose bullets. I'm hoping to get some if my cast bullets to work.

Was your original shooting with cast? If so, you generally want to be sized slightly over. I run a relatively soft 0.309 cast with hard lube for plinkers in my 30-06 with fairly good results.

Got a picture of the Krag. Seems to me that the Norwegens used an 8 mm Krag once upon a time

I was using plated 30-30 bullets. It's possible the roughness was destroying the plating.
I'm going to try 3 different bullets that I have used in my 308 with 16 gr of 2400.
Patches don't catch in the bore like they did when I first started.

It's a 1894 Krag with the front of the stock cut down by a previous owner.

A few hours of solvent, .338 bore brushes, and a cordless drill was required to turn my K98K RC from a sewer pipe bore to almost shiny with slightly frosted grooves.

I use 1 patch of fine valve grinding compound pushed through from the breach. Then I follow with a dry patch until it's clean. After that, I run aluminum polish through about 20 times. Followed with clean patches.
The bore scope shows no copper. With a mostly shiny bore. The rifling is very weak. I am probably going with the 35-40 rebore

Danes used an 8mm rimmed cartridge in their Krags - with a forward hinge on the magazine. The Norwegians used 6.5x55.
