Savage 110 rebarrel

[wyshadow]

First time posting here, and I read as much as I could on this forum. A little back story on me before I ask my question. I'm an avid PCP shooter for the past 10 years but I have been reloading PB for the past 8 years. I first started with a 22-250, then a 308, played around with a .223, and now have a 243 long action 110. I had my local gunsmith rebarrel the 243 to a heavy varmint 1-10 twist Shilen about 5 years ago. I bore scoped the barrel two weeks ago and noticed the throat is burned out but the barrel is still producing 3.5 inch groups at 500 yards. I am thinking of getting a 6.5X284 barrel because I already have brass and dies for a my .284 winchester bench gun.
Now my question: Can I ream my burned out 243 to a 6mm Remington? I would hate to throw the burned out barrel in the trash but give it a new life when it's time to rebarrel. I looked up the specs on the 6mm Remington and it looks like this could be done.

The 243 and 6.5/284 are both known as barrel burners. I suggest that the Savage 243 could be redone in 6mm Rem by "winding back" the barrel and recutting the chamber further forward to clear the throat area --it's only a 1/4 in longer than the 243. But you may be able to wind it back far enough to chamber in 6mm Creedmoor, which is easier on the throat area than 243 or 6 Rem, and get similar performance from less powder and easily obtainable brass.

I thought about getting a reamer for a 6mm CM but the 243 barrel has a 1-10 twist.

You would be better off to just buy my $289 pre-fit barrel brand new. You're going to spend the same amount rechambering your burnt up barrel. Then you can just pick whatever caliber you want.

I'm not really sure what the advantage to going to even more powder in a 6 mm would do. I would suggest at maximum a 6 Creedmoor.

I might go your route for a new barrel. My 110 is mostly a deer gun and will probably choose a 6.5x284 because I already have a set of dies. I'm just wondering if I could rebarrel my 243 to a 6mm Remington instead of throwing it away.
I don't care much for barrel burn out, and if did, I would've stuck with a 308. I guess I could not do anything to 243 and keep it the way it is but that's boring. Although the 243 is a great caliber, I just want to try something different.

I had a customer that rented the 6mm Rem reamer and sat in front of the TV and reamed his barrel by hand using a T handle. Set the brass protrusion to .130". I don't have that reamer because no one asks for it.

He must have sat and watched Avatar to get that done or Lord of the Rings lol

One of the reasons to buy a Salvage is to rebarrel yourself with a prefit

Plenty of companies now offering prefits for other brands...my last half dozen nut/prefit installs have been Rem700s -- McGowen barrels. Plenty more stock and trigger choices that way. I started with a couple Savage build but was always compromising on the other parts.

It shouldn’t be an issue, unless you really want to shoot factory ammo. Just load 90 grain bullets and less in the Creedmoor. Probably a lights out varmint rifle. Or just buy a new prefit barrel and install it yourself.

I looked up the specs on the 6mm Creedmoor and it looks like rechambering the barrel is not possible. The CM's case is shorter than the 243's case.

6BR.....is much shorter...or 6x45 (6mm/223)

But does the barrel have enough 'meat' left after the shortening/threading

 

[koger]

6XC?

Re chamber it. I have had 3 barrels on my savage re chambered to the same caliber. The only thing you need to advise the gunsmith is to also add additional threads to the barrel nut area because once they cut off the back of the chamber and re chamber you will not be able to set the head space due to the barrel nut need to be threaded further onto the barrel. Found this out on my first re chamber.

I have been thinking (ahead) to where I might have this situation arise and it occurs to me that you could safely pick up another 1/4" by undercutting ahead of the threads by that much to below the root diameter. This allows the jam nut additional over travel and since it is merely there to keep the barrel secure it should be fine.

That is exactly what we did and it worked out great.

OP, if you are thinking about rechambering to 6mm Rem. without setting the barrel back, it's not possible because of the different tapers of the cases. You have to go quite a bit deeper into the barrel to clean up the .243 chamber for a 6mm Rem. Same holds true for rechambering a .308 to a .30-06. Now a 6mm AI would clean up the chamber without setting the barrel back, but you would have to measure and see how much of the "burnt" area that it would remove -- maybe not enough if it's pretty bad.

 

[Hotshot]

The 6mm Remington case has more taper than a 243 Winchester. So if you try to ream the 243 chamber to 6Remington it won't clean up the area where the 243 is fatter.

 

[Hotshot]

You also can't shorten a Savage barrel very much on the chamber end because it starts to taper immediately after the threads.
