How do these two calibers stack up side by side? I couldn't find info. for the .22-243 in my manuals.

Thanks

I rechambered a 24" Remington 700 ADL barrel from 223 to 22-250 and later to 22-243. I was able to get 150+/- fps more with 55 and 60 grain Noslers. When I rechambered the 22-250 to 22-243, after around 1500 rounds, I cut the barrel back 5/8" to insure that I got a better throat for the 22-243. I don't think that I would bother to do it again, unless to get some additional life from a 22-250 barrel with a worn throat.

Yes....and that's about all the gain one can expect.

In reality there's very few wildcats that offer significant performance advantages over a standard cartridge. The best wildcats are aimed at getting around legal issues or offer a weight difference in the firearm.

The 22-243 is really too much of a good thing. Now I have several wildcats and enjoy velocity as much as anybody but I also like some efficiency. Too much additional powder and barrel throat wear for the 100-175 FPS gains.

I would recommend a 22-250 AI or the Swift over the 22-243.

Guys:

Here's some data on the 22-243, from an article written by James Mason, back in the 1960's, pretty interesting! 42/R-21/60 Hornady=3740 fps. 45/4831/65CFS?/=3530fps. 44/4350/72CFS?/3575fps. The groups all averaged around a half inch, and all groups were shot from a 26" barrel. Looks like the 22-243 shines with the heavier bullets.

I am a pretty conservative reloader, so it might be possible to get significantly more speed from a 22-243 than I did, but only with a pretty steep jump in pressure. I'm happy shooting 55 and 60 grain bullets from a Remington 788 with a 24" 1 in 8" twist 22-250 barrel.

VD!
When I look at the list of STANDARD cartridges today that were adopted or copied from wildcats your statement confuses me.

Old age is a high price to pay for maturity!!! Some never pay and some pay and never reap the reward. Wisdom comes with age! Sometimes age comes alone..
