Anyone here have any experiences with this caliber? Good or bad.

Basically a 224TTH Played with it some. I like it for heavy bullets in a fast twist.

The .220 swift don't always feed well in the '98 mausers but the 6mm Rem usually does and it makes a fair long range varminter.

Whether it's justified is something else.

The standard 6mm Rem with 55-60 grain bullets duplicates any need for a .224 bullet here......

For most folks the 22-250 yields just about all you can get from a .224 bullet of normal weight. When you want to push the VLDs the bigger case helps some.

For shorter ranges I agree with you 100%. We had some excellent results with the 69&80 gr Nosler bullets. On windy days they seemed to give an advantage over the shorter 243 bullets. The 75gr Amax worked great on the few hogs and Axis doe we used it on.

I would not get one is you were going to stay with the light 224 bullets. The gain is really in the higher BC bullets. The 243 or 6mm is still probably a better bridge between varmint and deer but the 75 Amax did its job very well.

The 5.6x57 has been around for a long time. Other than a very slightly different shoulder angle, it would be identical to a .22/244 or .22/6mm Remington.

Along with the TTHA handle it is also known as the "22 Clark".

Yep the Clark is another good case that was designed before they had real slow powder and 22 bullets that would handle the fast rotation. At least TTHA mentioned him in their write up.

"Basically a 224TTH"

Which in turn is basically the old-time (1912!!) .22 Newton. A 7X57mm necked down to shoot .22 bullets, later the .30/'06 with about .25" cut off and necked to .22 cal. It is covered in COTW pretty well.....

(Is there really anything new out there??)

Hey if you call it a new name and all the old people pass on then...... I really hard to find something new. Seems any more if you cange the shoulder from 28 to 30 then HEY NEW ROUND.

30/378, Actually the 22/6mm (224TTH) is not the same as the .224Clark.

The .224 Clark was designed in 1962 by Ken Clark. It is a 257 Roberts case necked down to .224, and then fireformed in an improved chamber with a 30 degree shoulder.

I built my first .224 Clark in 1988, and found that the 257 Roberts case (Winchester brass) when necked down to .224 had a capacity of 57.1 grains, and increased to 63.8 grains after fireforming.

I should receive my second .224 Clark back from my gunsmith by the weekend. This one is built on Rem 700 SPS (trued), Krieger 26 inch 6.5 twist SS No 3 contour barrel, Boyds Boys Laminated JRS stock.

I will principally using the Richard Graves 100 grain ULD Wildcat, and Garry Little's 105 grain HPBT's. (Sierra Matchking profile)

The rifle is obviously very experimental, and I am looking forward to testing it to see what it can do. Regards, Briain.
