Idaho Sharpshooter22-378 Ackley Improved...
I was rummaging about in the shop this afternoon, and found my reamer set and Neil Jones CPS dies for my 22 Ear-Ge-Splitten-Loudenboomer, along with the notes. I got 4800+fps with the Nosler 60gr solid base bullet, and nearly 4200fps with the JLK/Sierra 80gr VLD-style bullets. I'm beginning to think I may have to send that Savage 112SS-SS action back to Savage and get another 9" twist 223 barrel fitted...make that 2 barrels. Am I the only one out there that does things like this?

CheechakoYes Rich, you are the only wildcatter that does things that have no redeeming social value or benefit. ALL of my wildcats have resulted in tremendous gains in velocity, extended barrel life, and accuracy like you've never seen before.
It's been a while since anyone has played with the eargesplitten. I'll bet you could sell a few of the fire-formed cartridges to collectors. I have one in my collection and several guys have tried to buy it from me.
Go for it!

Ok, what's the theory behind the double shoulder? Is it from the same crazed mind that brought about a .22/378?

I only know what I was told about it. I've never checked to see how much (or any) of it is true.
The .228 Ackley Double-shoulder Magnum is based on a .300 H&H Magnum case. According to Richard Simmons in Wildcat Cartridges, P.O. Ackley created it simply to see if a long powder chamber would burn powder more efficiently than a short, wide chamber. Ackley loaded his experimental cartridge with a duplex load consisting of 5-grains of 2400 powder and “filled up the remainder of the case with #4350 powderâ€. Using penetration of steel plates as a substitute for a chronograph, Ackley estimated that a velocity in excess of 4,000 fps was reached using a 70-grain bullet. The results of the experiment were such that Ackley reported “surprise†at the efficiency of the double-shoulder design. Given the complexity of the case design, even Ackley deemed the case as “impracticalâ€.
Even though it's called a .228, mine has a 70 grain .226 Sisk bullet.
And that's all I have to say about that.

FjoldThe Savage action will take some work to get it to fit the 378 Weatherby case but the barrel change can be done at home.

Idaho Sharpshooteractually, it is a simple deal to make a Savage 112BVSS work. 112 is the long action. A BVSS is a stainless steel, fluted 26" single shot bolt action rifle, and I ordered mine in 223 to get the 1:9" twist. The bolt face will open up just enough to leave a thin ring of steel. I fired over 400 rounds thru mine (in 4 barrels) and it was a monster...
It would be much easier today, if you had a reasonably priced source for 30-378 brass.
