404-375 H&H

22/3030 Ackley Improved, 338/06 Ackley Improved; 257 Ackley Improved; and 257 Weatherby. I know, you say the Wby isn't a wildcat. the rifle that I load for has a custom barrel with short leade and tight chamber, so it requires loads well below factory.

I load one. 300 Ackley magnum. I use a standard 300 weatherby die to neck size the case. 88gr retumbo pushes a 180gr PP partition 3325fps

My first, fired live ammo today. 30-357 DGW.....A 357 Maximum necked to accept .30 Cal bullets.

Shot (4) each:
165g Hornady SST,same as I shoot from my Garand
100G Hornady Varmint round (designed for .30 Carbine- kind of a lead with a half jacket
90G XTP (a pistol bullet)

The rifle is a Marlin 336 that I re-chambered and set-up as a take-down, so today was a test of both Rifle and Ammo. Shot one each out in the woods with the gun strapped to my lead sled..me at the other end of a 30 ft line. No signs of pressure, so I took it to the range. Rifle functioned flawlessly, but I've got to work on my loads a bit.

I know this one ain't gonna take the world by storm, but that wasn't really the point... I did this just to prove I could. Next will be take-down barrel in .357 Max/.357 Mag/.38 SP. If that works, well...another switch barrel will be forthcoming...a standard cal or a wildcat? TBD

Just one, the tiny 20 cVartarg

Only one for me. 30 Herret in a T/C Contender.

I only load for one true wildcat and that is a .500 MDM Ultra mag.

.375 Rum cases blown out with corn-meal and a light pistol powder load semi fire-forms them, then trim to 2.79 and load-em up.

The first corn-meal load gets them near enough for full hunting loads. After the first full firing they are perfect and RUM brass lasts for a looong time.

I remember loading for the .458 Lott before cases and loaded ammo was available in the store. I had to physically import a reamer from the U.S for my gunsmith to chamber a rifle for me at the time and look where the Lott is now !!!

I also load for a 9.3x64 and accorded to the cost and availability of components it may as well be a wild-cat !!!

6.5mm Remington SAUM on a Remington 700 Short Action.

With 62.5 grs Hodgon Retumbo I'm pushing the 143gr Hornady ELD-X at 3070fps out of a 24 inch 1:8 twist fluted Criterion barrel and getting sub half MOA.

Ballistically, I look apon it as being equalivalent to a 24 inch .264 Winchester Magnum.

I have just started on a 358 RUM based on the 338RUM case.

Spooksar I see you have a 358RUM, could you PM me with some loads if possible.

Cheers

Greg

.22 Neidner Mag. Rimmed
219 Donaldson Wasp

25 Krag Ack. Imp (FL)
Oh, and soon the .250-3000 Rimmed

Updated, again, my wildcats and other folks' designs that I load, that might be considered wildcats or "proprietary."

I am still up a tree tangling with the wildcats and wish someone would shoot amongst us.

Somebody has got to get some relief here!

In the works:

A Remington Rolling Block 50-70 throated for my pet .510 to .512"/650 to 680-grain cast bullet at whatever speed will stabilize it in a 1:24" twist.
Smokeless will be easy, BP is questionable.
Might become known as the "500 Nitro For Black Powder Short Bus Express 1.75-Inch" if successful.

A .500 Buhmiller using a .500-caliber bullet rebated to .476" heel at bullet base, to sit atop a 470 Capstick case.

The .410/404 Jeffery Justified: Think .416 Dakota using different brass and bullet.
But boom stick is enabling the sickness with a suggestion of the .410/.375 H&H Unadulterated, aka his "400 Karamojo."

Somebody please shoot up into the tree where I am tangling with these wildcats!
