Gunsmithing 243 to 22-250

[new_guy]

Can I rebarrel a 700 in 243 to 22-250?

I know the bolt face is okay, but what about the feed rails?

I'm building up a dedicated p-dog rifle, and found a good buy on a 700 in .243. It's a '73 in "as new" shape, but the thin barrel has to go. The 22-250 seems like the logical dog choice.

From that, to this, 22-250 is a fantastic choice!

22-250 is my favorite caliber for varmints

Go with the Ackley version for even more fun. 50gr Ballistic tips at 4000fps.

If your building it for p-dogs that I might suggest the 22BR. It will burn a little less powder and still give you almost the same fps as the 22-250. Down side is brass will cost you more but the good thing is it will last a loooooong time....

Mine too

. I'm having mine changed into an AI (with a new barrel) very soon in hopes of being able to push bigger bullets farther. I also despise trimming brass for hundreds of cases at a time.

OP- You will find as I did that the .22-250 is a great p-dog round, although it tends to heat up the barrel in about 5 shots. Then there's the trimming thing to consider.........

The AI reduces the frequency of trimming.

I've read that, but isn't the trade-off fire forming?

With regular annealing (3-4 loadings), how many loads are you guys getting from the AI brass?

I got 5-6 w/ win. brass on my .280 AI with hot loads. Primer pockets started opening up after that. Tight custom chamber.
