I have a 12 FV in .223 (1in9 twist) that will shoot 69 SMK's but will not stabilize heavier bullets (i.e. 75 A-Max). If I rechamber this barrel to 22-250, will the heavier bullets stabilize due to higher velocity/revolution? Would another chambering work better?
I want to do something to this barrel because it just isn't as accurate as I would like it to be (no better than 3/4" @ 100 yards, usually closer to 1").

To get better groups you need to tune the load to the barrel.
I know I am really new at this, but is it even possible to get those heavier bullets to stabilize in a 1:9"? I was told to get any thing over 69gr to shoot well I needed at least a 1:8".
I have had good luck getting 77gr bullet to stabilize in a 9 twist 223. Other have reported using 75gr bullets without problems. Now with a 22/250 because of the higher velocity it will stabilize the heavier bullets in a slower twist, 1 in 9 is good for 80's in a 22/250.
Damn, I have to watch who I talk to, I could have saved over $100 on my .223 barrel going with a 1:9"!
Are you sure it's actually a 1-9 twist? The twist rates will vary slightly, and it might just be a tad on the slow side. Most 9" twists will stabilize a 75 gr. bullet, and only a few will stabilize an 80 gr.

Well, the recrown didn't help. I probably should just replace the barrel, it always did copper foul like crazy......
The next decision is 204 Ruger or 223AI. :-\
