Considering a 224 TTH

[1948CJ2A]

First of all, does anyone have one of these? I can't find a whole lot of into on it. I know its a wildcat. I also know the TTH stands for Texas Trophy Hunter.

Best I can tell it's a 6mm Rem necked down to .224 caliber. It appears to be extremely close to the the 220 Swift in terms of performance. I pulled a couple of SAAMI drawings, one of the Swift and the other of a 6mm Rem. The 6mm Rem parent case appears to be a couple hundredths of an inch longer. The taper appears very similar if not the same, and the neck angle very comparable.

Being so close to the Swift, I'm wondering what other differences I may be overlooking between the two. I handload so there's no need for comments regarding ammo availability.

Seems like a pretty neat 22 caliber centerfire cartridge. The other 22s I've considered in the past have been the 220 Swift & the 224 Weatherby. I like the 22-250 but I'm looking for something a little off the beaten path.

Have you looked at the 223 wssm

Or you could have a 22-250 or swift re cut to a AI version not not have wildcat cartridge that does nothing better than several others .

I'm not a fan of the short mags. A 22-250 AI would be kinda unique but I'm still leaning towards the 22-6mm/224 TTH.

Rifle Magazine's Varmint Rifles and Cartridges has an article on the T TH.The idea behind the round was a light recoiling deer rifle for small sized animals.Velocities around 4000fps with a 55 grain bullets are about 300 fps faster than the Swift.Seems like it would work well for it's intended purpose,but I would have liked to see how it performs with heavier bullets.The test rifle was an ER Shaw (Savage)with a 1/12 twist.At those velocities,it should work with the heavier Partitions,but they weren't' t tested.Looks like a great choice for long range coyotes,but I wouldn't take it to a prairie dog field.

I'm puzzled at how they get 300 fps additional over the Swift (everything else being equal), but without facts to argue otherwise, I'll go with it.

I'm actually looking at the ER Shaw Mark VII as an option. The quote I got (walnut stock, 22" barrel, polished blue, 1/12 twist) was somewhere around $850 plus FFL transfer & shipping. Then there's the 10-12 month turn-around time. I'm still undecided if I'll go through them or do something different.

I'm with you there. I'm certainly leaning that direction.

You might consider looking at the 22X6.8 from Black Hole. It is a straight neck down on the 6.8 SPC case. It is churning up super groups and velocities in their Savage and AR barrels.

That's certainly an interesting one there. I think I'd rather have the additional length of the Swift or the TTH. The SPC is a shorter cartridge.

Shorter to run through the AR but the safe pressures put out the velocity out of proportion to the case size. I doubt Ajax thing down range would react differently when shot with any of the three chamberings.

I hear ya. I'd be doing this in a bolt-action rifle though, not an AR platform.

The cartidge shoots like a laser out of a Savage barrels. If anything it excels because you can load long and get right up on the lands out of a bolt. It also is going to give substantial barrel life.

I could be wrong but he idea behind this round as well as others is shooting heavy for caliber bullets. Examples would be 80-90 grain pills They are relatively flat shooting , buck the wind well and do it with little recoil. Fast twisted barrels are needed to do so. A 1:12 isn't going to do it.

If I was planning on something like it I would build a 22-250 AI with a 26-28 inch Krieger 1:8.

I agree a 1:8 is the only way to fly IMHO if you want to step out on this one to handle bigger than coyotes. The 1:12 might well hobble it in all around usage eliminating some of the 70+ wonder bullets.

I don't disagree with regards to the barrel twist, but why not 1 in 10?

The 1:10 will have issues shooting much over 69 grains. The added velocity lets you cheat a bit as it would normally require a 1:9 to shoot those well.

A good rule of thumb is to determine the heaviest bullet you want to shoot and the proper twist rate and then go one turn faster. A 1:8 wil give you enough for all but the very heaviest 223's and stil will shoot the lighter ones though this one is not the gun for 500 rounds/day PD shooting.

I guess I didn't realize that vendors made 22 caliber bullets that are in excess of 70 grains. I just looked @ MidwayUSA and the heaviest they have is a Sierra MatchKing in 90gr. That's certainly a very long bullet and I could see a 1 in 8 being necessary there.

Interestingly enough, I went back to ER Shaw's site and their twist offerings in .224 caliber are 1-8, 1-9, 1-13, 1-14.

Since I do hunt deer, I could see wanting to use bullets in the 80+ grain weights so a 1-9 or 1-8 might be the better choice.

I guess the effects of that faster twist rate when using the smaller weighted bullets would be decreased velocity? Would that be all?

BTW - I'm not advocating this as a optimal deer rifle. I'm just saying I'd like that option if I buy one.

The little guys, 55 and under, can go much faster but at times the accuracy is degraded. By degarded it could be a factor of 0.2 MOA on some loads while others might go an extra inch. Depending on your usage this might come into play. The nice thing is there are some heavier varmint style bulets outthere that let us get away from that issue. I have a 1:8 223 that shoots the smaller 50's very well. It is a Black Hole tube and I am pushing them hard. That faster twis on a light varmint bulet will cause uber-explosiveness when it comes unglued on targets. Impressive on a 20 ounce PD.

The 90's routinely take a 1:7 but a 1:8 will handle up to 80's with no problems. The new "deer" bulelts in the 223 are all usable in the 1:8. Shot placement, of course, is paramont with any of those as with any bullet. No magic just becuse they are bonded or solid. Those TSSX types are killers and would work fine for you.
