All this talk of a faster twist in a 223 giving the same as a 22-250 is great, but there is no mention of what a 22-250 will do with the same twist.
I have both, an 8 twist 223AI, and an 8 twist 22-250. The 223AI has a #6 Broughton, 22." The '250 has a #7 Rock, also 22."
Slinging the same bullets (75 Amax) the 223AI will push them 3100 and the 22-250 will push them to over 3300. For that extra 200 FPS, I burn 8.6 grains more powder, both loads are using R-15. It doesn't sound like much, but I can load 500 223AI's with the same amount of powder it takes to load 380 22-250's. /ubbthreads/images/graemlins/wink.gif The 223AI will push 50's a little over 3700, I have never shot anything lighter than the 75's in the 8 twist 22-250, so I cant compare them there.
There is more recoil with the '250, I know that is relative with a 22-250, but not when you are spotting hits. If I crank the power down and hold the rifle I can still spot hits with the '250, but no where near as easily as the ack.
The '250 is louder, like some have mentioned. But that is pretty much negated when you are wearing hearing protection. /ubbthreads/images/graemlins/wink.gif
The '250 heats up ALOT quicker than does the ack. Not many PD towns here in michigan, so I can deal with that issue. I have a savage or 2 if I was going on a PD trip, cheap barrels and easy to change. /ubbthreads/images/graemlins/laugh.gif
As far as shooting at distance, I cant think of a shot that I missed with the 223AI where I would have made it if I had been using the '250 and that extra 200FPS. /ubbthreads/images/graemlins/confused1.gif
I still like my 22-250, but I have to give the edge to the 223AI. It doesn't give up much, even when you stretch its legs a little. I have 300 rounds throught the 250 and I am trying to decide now what to have it rebarreled as when it goes south. Thinkin' maybe a 25-284 next, or maybe a fast twist 243 for the 115 DTAC's, probably not much barrel life there either /ubbthreads/images/graemlins/smiliesmack.gif /ubbthreads/images/graemlins/laugh.gif
