Can I change the barrel on my Colt AR15 and shoot somthing other than .223? Im thinking 308 or 7mm-08?If no what calibers are available for the 15 platform?6.5 AR?
AR-15s are also chambered in 223WSSM, 243WSSM, 25WSSM, and I believe a few other bigger bores, like 300 whisper, and a .45 calibre. (To add to Coop2424's list)

Only the AR for 223 if the decision is between the 2 rounds for a bolt gun then its not a choose 22-250. I would want a 223 AR because i always seem to miss judge the distance on my first shot... I think though you have to add about $400 to you budget to get one tho.
I like the idea of the 243 wssm for my ar 15....
As stated you wont find a 22-250 ar15 the coal is to long for the mag. There a lots and lots of other cals out there for the ar15. The WSSM are a good one and the .223wssm is faster then the 22-250 or 220 swift from all the load data Ive seen. Theres a 6mm turbo thats seems to have good ballistics too. Id say look around online and decide what cal fits your needs. The wssm and ossm are to fastest for cal size in the AR15 and feed with out a problem.
comparing cartridge to cartridge, 223 to 22-250. I dont care for AR's anyway so will not address that.Since both are meant for varmits and coyotes I do not consider energy or velocity at impact a factor. If you are having trouble killing with either, consider shot placement.The bottom line is at long range you must hit the target the most important factor for that is consistancy, consistancy!!! look at the slow 308 with heavy bullets, one of the most effective long range cartridges in existance.For long range use I give a fast twist 223(7-9 inch) the edge over the normal (12-14 inch) 22-250, due to the availability of heavy bullet use. the heavy 223 has a higher ballistic coefficent. my 2Carl
Well I told myself that I wasn't going to chime in here but my fingers seem to have a mind of their own!!! Basically it boils down to what type of terrain you will be using you gun for. First off let me say that the areas I hunt can give me shot opportunities further than I am capable of shooting. My experience using a .223 has not been very satisfactory for me on anything over 200 to 250 yds. My .204 seems to be on step up from a .223 under my hunting conditions using a 32 gr Vmax. Now my on a 22-250, it will do just about anything you need to do except now you are into a bolt gun. My current favorite coyote gun is a .243 bolt just because it knocks the dogs down and they stay down. I am currently building a .20 tac AR that is made to shoot 40 gr bullets which is very close to a 22-250 in terms of velocity and energy. My next build will be a .243 WSSM with Mike from DTech. While you don't have the magazine capacity of the .223 and .204 you probably don't need more than 5 or 6 rounds in a magazine at any given time anyway. The .243 WSSM will be more expensive to shoot given the cost of the brass and expensive magazines unless you know how to modify the magazines to accommodate the fat cartridges. You will definitely need a brass deflector so you won't lose any of the brass. Also some of the heavier 6mm bullets are too long to fit in the magazine. These are some of the issues of shooting the WSSM cartridges but may be of no importance to you. I would definitely look into a .243 WSSM as it has more versatility. The 6 x 45 is a very stable accurate cartridge also (.223 necked up to 6mm) but somewhat lacking in velocity but is very popular also.
I hope 5200 fps was a typo , my 22-250 ackley comes nowhere near that speed.
