Rem 700 22-250 question for the pro's

Q for you pro's. I have a remmy 700 22-250 factory setup. Wondering if it would be beneficial and worth the expense to set the barrel back to eliminate the lengthy throat in the factory barrel and if so is there is enough room to upgrade to the AI chamber or would it be much more worth while to just rebarrel? Barrel is a factory varmint and is running .70-.75 spread now.
Thanks all

It's only money... :D

Your accuracy isn't great right now... and might not improve... or it might, no way of knowing... a lot of them shoot in the high .300's.

If you really want to give the A.I. case a whirl, this would be as good a time as any to set the barrel back and chamber for the A.I. round. The barrel requires setting back a few thou to correctly headspace to start with... so set it back enough to make a short throat and a fresh chamber. Then as this barrel wears out you will have lots of brass fire formed for your new barrel...

Rem 700 22-250

I have a 220 Swift that had more rounds than I can count through it. It finally quit shooting. I cut about 1 1/2 inches off rethreaded and rechambered to 22-250 AI.
I planned to fireform about 1500 loaded 22-250 cases that I had on hand.
Instead I took it PD hunting this June. It shot extremly well. I was very suprised at how good it shot.

I have a new barrel chucked up in my lathe at this time. In the next few days I expect to thread and chamber.

I will then load the 1500 fire formed cases and work up a good load.

Hope this helps.

The 22-250 is known to erode the throat rather badly, especially if overheated in the prairie dog wars. Before making the decision on setting the barrel back, I would get access to a borescope and determine if the long throat is because of factory throating or barrel erosion. It will be very obvious if it is eroded.

Many 22-250's that I have borescoped have shown significant erosion and frosting, but continue to shoot better than you would expect. The general routine is they continue shooting better than expected until one day the just stop shooting, sometimes even keyholing.

If the barrel has never shot well, it would be difficult to determine the cause without eliminating other factors such as bedding, scope and loads. However if everything else has been eliminated, I would not consider that barrel a candidate for setting back and re-chambering. There is nothing magical about an Ackley Improved chamber that will make a bad barrel into a good one.

And finally, the thing is a Remington!

You probably picked that up from those meatheads over on 24hr campfire.
 
The gun is new. Has less than 200 rounds through it. Just trying to get as much out of it as I can since it isn't stellar performance now.
