So I have been wanting to do this for a while now. I finally got everything I need except the reamer and tomorrow I will get that ordered.

It is a wildcat based on the 256 Winchester Magnum which was popular in the 50's and 60's. There were factory loads as well as revolvers chambered in it. It is a 357 Magnum necked down to shoot a ~6.5mm bullet.

Because I wanted it to feed from an AR magazine it had to be rimless and 223 Remington is close, cheap and plentiful. But because the 223 is slightly smaller than 256 Win Mag I need a custom reamer. I am ordering it tomorrow.

To make the cases I cut a 223 case at 1.280”. I use 300 Blackout does to partially form the neck followed by the 256 Win Mag dies to finish making the brass. After firing the body can be sized using standard 223 dies. I will use the 256 Win Mag dies to bump the shoulder back into spec. In the pictures that is a 140g 6.5mm bullet and it doesn’t go past the neck at 2.19” overall length.

I am using a Model 7 to build the pistol. It was sold as just a receiver so it is legal as a pistol. I am building it into an XP100 clone that is rear grip that feeds from an AR magazine. I will use a 7 twist barrel somewhere between 8" and 12" in length.

I am having a pistol stock made that will be inletted for PTG AR bottom metal. Rather than use off the shelf wood I am using spalted elm from a tree cut off my property. The tree was here on the family property that I grew up on and has been here since I was a child. Makes a connection to me and where I grew up and now live.

It isn't a long range caliber but should make for a fun shooter with heavy, high BC bullets. I do not plan on shooting subsonic but it will definitely have a silencer.

I've been struggling with a name. First it was 6.5 Kurtz, then 6.5 D-S but then I thought 6.5 Creedless would not only be fitting but funny as well.

I will post updates as process is made.

There's a local guy who built a rifle running a 6.5 Creedmoor reamer in short. He calls it the "6.5 Creed more or less." I don't recall what his objective was, he has all sorts of weird stuff as he's got a pile of tools and lots of burnt-out barrels he chops/re-chambers for free.

Good luck with your project. I've got a few wildcats of my own, they're fun to play with.

My biggest reason for going the way I did was cost. I use standard 223 dies and standard 256 Win Mag dies. I knew I would need a custom reamer but with any wildcat you probably will. And considering the short barrel I am using I do not need a lot of case capacity.

If I can get to 2,000 fps with a 125g bullet I will be very pleased.

100 Nosler BT from a 10.5” bbl, 2178 fps
125 will be about 2000 fps from a 10.5” bbl.

I have a bolt gun in 6.5 MUTT also.
120 Cartarouchi VLDs @ 2400 from a 26” bbl.
140s were really slow, forget how slow but slow enough I decided 120s were as heavy as I’d use.

You’ll enjoy the 6.5 Creedless, wildcats are a little spendy but definitely fun.
