Fast twist .224 for yotes

I have an urge to build a 1:8 twist 22 cal with a 24”-26” tube for coyotes and other varmints, once I locate a donor action. I’m thinking a vanilla 22-243 as I have a ton of 243 brass with no current use. My other thought was a 22CM, but not much for reloading components currently available. Looking for input on a couple things:
- any real advantage in one cal over the other?
- looking for advise on a 75-80 grain bullet that will give bang-flops on yotes out to 600 yds?
- not real concerned about barrel life but would 3400-3500 be attainable in the 24” tube without really heating it up?
Thanks

Well you could build a 22-250 Ackley and use the 243 brass, for it.There is some trimming required but you start off with thicker neck and you can trim that to fit your chamber.

I have a 22-243 shooting 75g amaxes. Using h4831sc 210m primers win brass they are about 3500 now was faster when new. I would say go straight 22-243. Mine is at about 700-800 rounds still shoots good but velocity is down a little bit. The barrel has eroded.030 but it still shoots great.
 
Very similar cartridges performance wise. A couple things that would sway me personally if I was choosing:

Shoulder angle much sharper on CM than 22-243. Theoretically controls gases and erosion better.

If you re building a fast twist to shoot 22 heavies then CM will better fit a short action rifle magazine. If you shorten the free bore on the 22-243 to compensate for this they you re stuffing a high BC bullet deep into that 22-243 case.

Good luck with your decision.
 
22 Creedmoor is the practical choice here. Can get dies from Hornady for a reasonable price, and brass from Hornady, Alpga, ADG, and Peterson.

8 twist will be good for 80gr or lighter, I run a 7 twist on mine

I know some just hate hearing the sound of the word "Creedmoor" but I think you're right and it is the practical choice.

22CM gives the same or better performance than a 22-250AI but with no fireforming or brass prep. Is equal to or outperforms the 220 Swift especially with long bullets in a short action and has much better brass. It's not that I don't like either of the others, I'll always have a soft spot for the Swift, but for what the OP wants, the 22CM checks all the boxes the best and the easiest.
 
Thanks for the input. For the 22CM brass I see both large and small primer options. Is there an advantage using one over the other? I

In all honesty with the way things are right now I really wouldn't worry about it to much. It's kind of a take what you can get market.

I don't know if you already have a barrel picked out yet but if you don't, I'd seriously consider one of Bartleins new 400MODBB material barrels. They're supposed to last somewhere around 1.5X longer than the standard 416 Stainless barrels and I'd go with an 8 twist.
 


I just an old man. That has been shooting a 220 Swift for more years than most of you have been alive.
My swift will push a bullet that on a foggy day will burn up in the air before it hits the 100-yard mark.
I am within 3 inches of dead zero out to 300 yards. I like pills of 35 and 40 grain.

I run large primer pocket brass in my rifle. The small pocket will offer a thicker, more durable case head. If you want to run the pressures up, the primer pocket will last more firings than a LR pocket will. Also, many shooters believe the milder small rifle primer will lead to more consistent accuracy
 
I have two different 22cm's that I have been running for years. One is an 8tw and the other a 9tw. The 8tw is a 22" and runs the berger 80's at 3400 with h4350. The 20" 9tw runs the 69tmk at 3510 with Varget. Both are extremely accurate. The 80's of course buck the wind a little better and hit like a freight train. I primarily run SRP Lapua brass, but started with LRP Hornady without issue. I am not at the very top end of pressure, so brass life has been excellent. With the 80's, I got up to 43.0gns of H4350 and it shot fine, but 42.2 was really the sweet spot for this rifle, so that is where I settled in. Have not run the 75eldm or 77 TMK, but those would also be excellent choices for this cartridge. "Bang-Flop" is the norm on coyotes and would have no hesitation whatsoever to run this rig on whitetail or antelope either.

I am right there with you! Love the mighty Swift and have been shooting it since the late 70's. I have several other varmint calibers but I seem to always grab the Swift when heading out the door to slay the varmints!

I am curious about your 22CM as compared to the 243 Win. Reason I ask is I am shooting the Barnes 80 gr TTSX at 3378 fps out of my Tikka T3x Superlite in 243 Win. What would be the advantage of one over the other, or is there? I just don't know enough about the 22CM to know the difference but with the 243 Win, since it has been around forever, components are readily available (well, maybe not as much today but you know what I mean).
 
I shoot the 77gr Barnes LRX @ 3430 fps in my 26" 22cm, could probably push it harder but it shoots well and is plenty fast for me. It has a BC of .404, compared to .331 for the 243/80ttsx
