22-250AI or 22-243 that's my question

[bruton]

I'm receiving a new barrel, it's 26 " 1-12 twist, I want something different ! I'm using it for coyotes to about 500 yes max, I want fast and accurate , mb even a 22-243 AI , what bullets will this stabilize in a 22-243? Thanks Jeff

At the bottom of the page is a "stability" calculator. Hope this helps, Tom

before I'd do a 22/.243 or the 22-250AI, I'd take a seriously look look at the 22 Jaybird!! Better case design means better barrel life and accuracey as well. The Jaybird case is pretty much an improved 22-250 based off a .243 case. The over all length is 2.00" (this is great when factoring in fire form case shrinkage). The shoulder deminsion is 1.550" and the neck length is .30" with a 35 degree shoulder angle. Hogdon lists loading data in their #26 manual. The 22/.243's are well known barrel burners as well as some others based off that case with a very short neck length.

The twelve twist barrel kinda limits you to 60 grain bullets and lighter in weight, and this round is perfect for you. Plus knowing it's a Kenny Jarrett design tells me it's a good one. I'm going to rechamber a Savage barrel in this caliber, and may even do one in a 6mm version when my 6/250AI barrel finally goes south

Any of the .22 centerfires you're considering will be "barrel burners". One, really no better than the other.

If you only have a 1:12 barrel and you are only going out to 500 yards I would just stay with a 223 and have some barrel life. If you want to run bigger case size for a 22 get at least a 1:9 or better yet a 1:8. A good 223 should own the ground out 500 yards. The extra rounds you can shoot to get trigger time and practice will make more of a difference than the gun will.

I shoot a .223 Remington on coyotes a lot of the time around here. We get some pretty good sized dogs, and 35lb. ones are getting to be rather common anymore. Most of my hits have been under 300 yards, but have taken a couple dogs close to 400 yards. To me anyway, the .223 is starting to get marginal after 400 yards for that clean one hit kill. At 300 yards it drops them like a rock. Looking at the ballistics chart, and using the data from my Remington, I see 280 ft.lb. of energy at 500 yards (3200 fps .255B/C), and about 390 ft.lb. at 400 yards. But 548ft.lb. at 300 yards. Now had we been using the 22 Jaybird at 500 yards with the same 55 grain bullet will give you 471 ft.lb. of energy (3900fps), and 850 ft.lb at 300 yards.

I like the case design of the Jaybird, but would like it a lot better in 6mm, and a 1:8 twist barrel

22x47 Lapua would be my choice
