    I would assume it would be the 243 necked down to a .224 diameter.

    Yep, a 243 necked to 22 cal. And if ya don't put enough 4831 in it it'll come apart on ya. Was standing w/in 10' of one when she when up in smoke. Been skeer'd of 'em ever since.

    Something about secondary or reflected pressure wave????

    Just tho't I'd mention this. Lots of 'em out there doing well.

    One of the shooting mag writers made one, (Carmichel from outdoor life??) called it a 22 Cheetah. Actually trhat was a 22-308br. If I remember correctly it was a real screemer but a little finiky. There are a lot of variations of them out there. A little faster than the 220Swift.

    Just drive out to western oklahoma and ask them all about it, they will give you a ear full!! Real popular round out in that neck of the woods. Personnally i would tell you to go with something in 6mm, better bullets

    I have two 22-243 ackleys right now and have nothing bad to say about them except they can be hard on barrels. Take 243 laupa brass neck it down to 224. My 22-243 ackleys are wonderfully accurate at 3600 fps plus with 80 grain a-max's. No problems finding a load to shoot. and not to finicky with 7828 imr and 80 grain pills. I would only go with a 22-243 if you went with a 8 twist to shoots the 80 grain pills. Thanks Reed

    The original 22-243 was developed by Paul Middlested, of San Diego, in 1965. As noted, it's just the .243 case necked down to .224. The .243 case body remains the same but the shoulder angle is increased to 30 degrees.

    FWIW, I've had good results with H414 in all my big case varmint cartridges, and using only one powder (and a ball powder, at that) makes reloading a lot easier.

    Guys I am lost Her .

    if an 22 243 is an 243 necked down to an 22 bullet .

    what is an 22 250 ?

    If you start with an 308 case . then you neck it down to an 6 mm bullet that is an 243 .

    If you shart with an 308 case an you neck it down to an 7 mm bullet it is an 7 mm 08 .

    If you start with an 308 case an neck it down to an 22 bullett it is an 22 250 .



    That is the way I under stand it .

    So what is an 22 243 ?
    or is it an 22 250

    Nope...

    A .22-250 is the "250 Savage" necked down to 22... NOT the 308 or 243 necked down.

    The "250 Savage" is a smaller cartridge, originally designed to be used in the Savage M-99 lever gun.

    I sorta agree with Lerch and Wildcat, i.e. I slightly prefer the 243AI over my other big cartridge varmint rifles (22-243 Middlested, 220 Rocket, 22-250AI)...even for PDs.

    I concur, go 6mm... or go home. No need for a .22 Centerfire in my world. I guess if I lived somwhere where there were massive PD towns I would feel differently... but then it would be a .223 or .17 of some sort for volume shooting. ~JT

    Dont rule the 22 cals out look ate the b.c for the 224 80 grain a-max at least .475 at 3600 fps compare wind drift and and drop and theres not too much that will run much better for groundhogs. I believe every cartidge has its place .The 80 grain .224s carry near the b.c of 6mm cartidges faster for less weight. I would not rule out a 22-243. Excellent brass 243 laupa, easy reloading, neck down. And more than adequate for deer sized game out to 500 yards. I love 6mms,25.7mm,30, 338's as much as the next guy. But if I were to have one rifle for all my hunting needs it would be my 22-243 ackley with 80- a-max in a 30 inch 8 twist tube. there are many great cartidges out there but dont over look the fast twist .224's /ubbthreads/images/graemlins/wink.gif
