22 Super PDC

[OYSTERBOY]

Hello all. New to the forum, Thanks for having me. Looking for info or what ever I can learn about this rifle. I was gifted this rifle so know nothing about it.

It is chambered in 22 Super PDC, It has a 281/2” 1” OD. S/S Fluted barrel. Twist ?. It has a Remington 600 action. Canvar trigger from Denver Co. Conetrol bases & rings. Bausch & Lomb 6x24 Balver scope. This rifle has never been fired.

Any info will help. Mainly looking for Dies, Which I don’t think I will find. PICTURES INCLUDED. THANK YOU

Do a chamber cast an go from there. It's a new one to me. Is the bolt face a 223 or PPC or 308 ?
Is there a gunsmith name on the barrel? Good luck an keep us informed. Might be easier to just rechamber the barrel to a standard caliber.

Looks like it is a reformed .243 case, high velocity light bullets. Probably a 1/14 if intending to shoot 40-55 gr bullets over 4000 fps.

Short article in Handloader #127. Same article reprinted in Wolfe's Wildcat Cartridges Vol. 2. It looks like a 40* Improved 243 with a longer neck. Huntington made the dies... but that was 1987. Some giddy speeds with 40-45gr bullets in a 26" barrel. It sounds very similar to the 1st 22 CHeetah.

There's also a vague memory (not always a good sign) of someone in Precision Shooting from around that same time frame writing about the Super PDC. Maybe Bob Jourdan?

I'll bet it will not shoot good enough for Benchrest matches .

Article on the .22 Super Prairie Dog Cartridge (PDC). In case someone just has to have one, bibsmachine on this site has a reamer for sale cheap!

Was that an attempt to be helpful?

Interesting point about the above article. The author had considered a 30* shoulder. Had he opted for it, he would have come very close to designing the .22 Creedmoor -- 35 years ago!

Well dang...is there anything regarding esoteric gun stuff that someone on this forum doesn't know!!?? I just learned a bunch

I STILL HAVE THAT RIFLE, INSTALLING A NEW EXTRACTOR IN THE BOLT, THE OLD ONE WAS BROKE, ANY ONE HAVE ANY IDEAS ON WHAT TO USE TO FIRE FORM SOME CASES FOR IT, TO GET SOME DIES MADE, NEVER FIRE FORM BEFORE, WOULD LIKE TO DO IT MY SELF. THANK YOU

Sure looks like a nicely put together rifle and stock. I am curious if you ever checked the twist.Probably a 14”, I have a 22-250 AI with a 12 and like how the various 53s and 55s perform on pd’s . I hope you get some dies made and report back.I recently got an inexpensive Teslong borescope from Amazon and have found it very useful to my cleaning technique.I have a used 204 that amazes me how well it shoots even though the borescope might suggest otherwise.My thought here is before ordering dies it might be a good thing to evaluate the bores condition, if nothing else it will give a baseline as to where you are starting.Hopefully it’s not too bad and you can proceed full steam ahead.

You asked for some ideas...just my opinion. I've fooled around quite a bit with this 22-243 case. I've had it in .22/243 (nothing more than a straight neck down to .22 caliber from .243). My current one is a .22/243 Imp 30* shoulder (not the Middlested version). I built a fire-forming barrel for it and it just happened to shoot really decent (.3" groups)...soooo I went back to my old method of a few grains of pistol powder, cream of wheat and a wax plug. I did almost all the fire-forming using the COW method. Worked very well. I then fired a few full power loads...and then sent (3) fired cases to Whidden Gunworks. The dies worked out extremely well (but "All" my dies from them have...Lol!). I used Lapua .243 brass. I turned the necks down to .014" wall thickness and that has worked well. I can't strongly enough suggest to you to have a chamber cast done on this rifle to find out exactly where you are at. I know of (4) different versions of this wildcat and have been told there are more than that. I use this cartridge for extreme range Praire Dogs (beyond 700 yds out to 1200 yds). BUT my set-up is for heavier bullets with superior b.c. A Kreiger 7.7 twist HV barrel. Good luck with your decision. It's a really nice cartridge.

I tried fire forming a 22/250. and it told me a lot. it gave a shoulder that formed well to the chamber, But split in 4 vertical places in the shoulder area, Telling me I'm moving to much brass. so I need to move the shoulder more forward so I'm not moving it so much. Then fire form it again. I THINK.

Try annealing before FF. A hand held propane torch works OK if you heat for a reasonable time. Try it on a couple cases. I FF 6BR to 6BRX with a normal powder charge and a bullet. Never annealed. The shoulder moves 0.100" forward without splitting.

Looks like Some of the Holland built rifles.

OK how did it shoot ?

THIS IS WHAT I ENDED UP WITH.

I thought 243 was the parent case?
