Rebarreling a Rem.?Best Caliber Choice?

[Dust270WSM]

I am planning on buying a used 22-250 Rem. SPF from a guy that has ran about 100 rounds threw it. The gun is not very old and in great shape. What I am thinking of doing is rebarreling it to a little faster cartridge. I have 2, 22-250's all ready but with the short action I now there are a bunch of choices I can go with. I would like to be able to shoot 55 grainers at about 3800 to 4000 feet a second.

Leaning toward the 22-250 Ackley. But not sure. What is Ya'lls opinion?

I dont think you will gain much shooting 55 gr bullets at 3800 or 4000 over the standard 22/250, i know thats faster but there is only so some much you can do with a 55 gr bullet. have you every looked at building somthing to shoot a longer more stream like bullet? I would say check it out I think you will find there is somthing to be said for going alittle slower with better flying bullets.
just somthing to think about, good luck.

Dust...you have two high-power 22's and you want to build another?

I agree with 338Legend. Consider something a little larger, with a better BC. For instance, consider the many .243/6mm caliber choices. Some of them shoot pretty fast, have great choices in bullets and with their high BC's will buck the wind at long range (read: 1k)

Ever think about re-barreling with about a 1/6" twist and shooting the 90 gr VLD's out of a 22-250? This is something that I've been interested in for a while now. My other choice would be something in a 6.5mm, such as a .260 Rem.

I think you can use a 1-7 twist for the 90 gr bullets. but I like the .243/6mm bullets better. the 107 and 115 gr bullets just fight the wind better.

+1 on Legend's comment

I'm also pretty sure he's right that 7 twist is fast enough to shoot the heavy 22cal bullets

You can actually rechamber the current barrel in 22chetah MKI and get the speed you are looking for. I have a 700 rem, was a 22-250 varment, I rebarreled it with a Hart barrel with a 1 in 16 twist. I burned it out on prarie dogs, rebarreled it with a Morrison 1 in 15 twist. Very fast.

A 22-243 middlestead if you want to stay with .22 cal

I am not thrilled with the AI version of any caliber, except for the 35 Whelen AI, and only for head spacing.. I have had both 22-250 and 22-250 AI.. saw better groups with the standard 22-250. had a 243 and a 243 AI.. neither was worth a darn, have a 257 Rob.. had a 257 AI.. the AI was consistently a more finicky round than I personally wanted to deal with.. and it would still not out shoot my 257 Rob.. so I sold it.
if you are wanting my opinion; here it is. since you have two 22-250's already... wild cat a 22-08. leave the taper alone, leave the shoulder alone.. neck it down to a .224". the 22-250 has a big taper.. this should make an interesting round. the 308/243 win case is thicker, has less taper, and if you do it right should send a 55 grain out at approx. 3900 FPS.
have fun.

I have a rem short action chambered in 6x284. I have pushed 70gr bullets to 4,000+ and 87gr V-Maxs to 3650 FPS. Buy 6.5x284 brass run them through a 6x284 fl size die and your done. No fire forming. Simple as apple pie.
