Its your call Ken. If you want I am positive we can find a way to muster up some suitale loaded .220 Howell. I know of one active loader nearby you by who might be coerceable. � Thanks, but I'd probably better leave it as-is for now. When I decide how and to whom to pass it along, he can decide who'll be loading for it. And whoever'll be loading for it can decide which powder to use. It's never been fired. It was to be the ultimate of my three .220 Howells, and I scooped enough bucks into it to make my knees watery whenever I even think of what the total would be. I aimed to shoot the heck out of it, of course, but got it � complete and ready to go � just after the stroke that killed my hope of ever shooting again. Several surgeries and complications have further doomed my shooting. I have a hard case, the custom dies, 100 or more head-stamped virgin .220 Howell cases, and over 6,000 Hornady 75-grain Hornady A-Maxes for it. I also have four scopes, with rings, for the Talbot QD mount. The scope that's on it now is a stainless 32x Weaver. Planned to add something a bit more powerful but had to abandon that notion (the Weaver came when I was in the hospital). If you have QuickLOAD, you can get some idea of what to expect it to do. I set the seating depth (in QuickLOAD) to 0.555 inch (shank 0.375 inch) and ran the scale for optimum powders to fill the net capacity of the case to 90�100% full and 50,000 lb/in� maximum pressure. IIRC, Ramshot Magnum would theoretically poke that A-Max out of he 26-inch barrel at 3,300�3,400 ft/sec and a tad less than 50,000 lb/in�. Oehler's Ballistic Explorer predicts that such a load would make the classic .220 Swift factory loads look like grade-school spitballs beyond about 200 yards. These 75-grain A-Maxes look like they oughta do a coupla hundred ft/sec just sittin' on the shelf!

Ken, honored to say the reamer for this intriguing barn burner of a cartridge sits here at my humble digs.
I would imagine that working with a soft blank, I could gen up a neck bushing die, to be suitably heat treated afterward (are you listening tex n cal ?) I hesitate to try and do initial case forming with a set up like that.
I've got a hunch that it WOULD work, though.
Win .270 brass to start, right ?

.270 brass'd make suitable cases, all right, but I'd prefer .25-06.
Two preliminary steps'd be necessary. (They won't form in just one pass. You can easily guess how I know!) � Start massaging the shoulder back with an 8x57mm Mauser sizer. � Continue massaging the shoulder back with a 7x57mm Mauser sizer backed-off about 0.10 inch.
The resulting case should then form properly in the .220 Howell sizer � and need only be trimmed, reamed, and probably annealed.

What a great crowd of A+, top shelf gentlemen.
I will truly look forward to pics of this soiree!

� I scooped enough bucks into it to make my knees watery whenever I even think of what the total would be. � Having thus begun, I reckon that I oughta add a few major details � � original Nesika bench-rest action (single-shot) � 26-inch Broughton bench-rest barrel with Howell straight-taper contour for maximum stiffness � H-S Precision tactical stock with integral aluminum chassis (glass-bedded) � Remington trigger (with safety removed), with Kiplinger single-set finger piece � Talbot QD mount � Harris bipod � butt monopod Since I don't trust variable scopes, and prairie-dog towns are at a variety of long distances away, I opted for the Talbot mount (which always goes back smack to zero) and four good more-reliable fixed-power scopes � 8x, 12x, 24x, and 32x � to be zeroed for whatever range of distances that I'd be shooting. Designed and commissioned this hummer to be a "field model" bench-rest piece.

No doubt about the fine company. While I've had the pleasure of you and your son's company, there's 20 more hands I'd definitely like to shake in this upcoming crowd of folks. I could definitely bore Greg and Ken for at least one Happy Hour.
This would be a tough one to pass up. I'll look into it further,Tom.

GTC so a stick of, say A-2 tool steel 1.25" dia would work? After machining - Austentitize in stainless foil, air cool, Harden & double temper to Rc 56-60? I think someone once told me most commercial dies are made of A-2, as it changes dims very little in hardening. I could likely round up the material pretty easily, though I'd have to farm out the heat treat.

I wonder how many cases could be acceptably formed in good unhardened tool steel.
After all, once you've formed a batch of brass, you don't need forming dies any more.
Also, you don't need forming dies if you use the sizer dies that I mentioned above.
Some dimensional variation is acceptable from a forming die anyway. The sizing die trues 'em up, doesn't it?

Back around the time when Joe Garagiola had hair, one enterprising soul made a chamber cast of his whomper, poured a can of hard plaster around it, melted the chamber cast out, and cobbled-up a few cases that his sizer would accept. Probably hadda use gobs o' lube.

Ken, I've got some large rimmed .45 body forming dies I made out of the crops off of mostly octagon Badger barrels. They used to use a .8750" "Fixture" on the muzzle end of their blanks for their deep holing and rifling,....it sure made things pretty easy and straight forward......prior to crowning I'd just pick up that Dia., and thread 14tpi, Run the reamer in.....than lop off the 'Drop' (and crown). Most everybody wanted 32" or 30" barrels, so the 36" blanks had adequate material (just) to spare. The Chro moly steel, polished out has literally done 100s of cases without a scratch or a hiccup. These are of course, STRAIGHT cases,.......I've not all that much experience in re-forming / wildcatting the bottlenecks (yet ) In truth, it all seems pretty straightforward from this vantage point.

Cool we are.
August here will probably be nicer than wherever you are at the time.
Unless you join the party, you will never know just HOW COOL the CampFire Shindigs are. I seem to meet the nicest people there, instantly dear friends, who were strangers before. This is one of the big opportunities the 24HCF folks have created. Don't miss it. Judy and the kids are planning on going, me, well depends on what is going on the farm at that time. � When Judy's around, does anybody notice whether you are? No,I'm not noticed,that gives me the chance to sneak away and do something fun. this is top of my bucket list....looks like my main project will be in the final stages...working on 2 others to accompany me

I've made a passel o' goodies from shop scrap. Once made a beautiful, ever so carefully fitted barrel-band swivel base � lotsa hand work with files � and found (when I went to blue it) it was stainless!

Everything that I'd made at that point � from the same box of scrap � had been chrome-moly barrel stubs.
