Wrong Cartridge. I'd recommend looking at a more "traditional" Cartridge that was intended for lighter bullets. Depending on desired speed there are multiple choices.
So you're going Ackley? Then you need custom Dies? I was just thinking straight neck down. I don't know if I can hunt with the 7's due to my Pectoral being gone on my shooting shoulder. Are there sufficient All Copper 25 Caliber projectiles to consider? /// Edit: 25 Wby Mag comes to mind with...
Just a couple 2 or 3 years ago I posted a 7mm Wildcat design Perfect for the 3.3" Standard Rifle. On paper it allocated the perfect amount of room for the long for Caliber high BC projectiles as this is the primary reason for the Cartridge. Now after Hornady has come out with their version...
My experience has been these larger Caliber Wildcats like the .338-06 for instance, the .308 Caliber actually outperforms the larger Caliber bullet downrange. Unless of course you are seeking a subsonic Rifle.
For a 40 Degree shoulder the 7mm SGLC is the best one for case capacity (Simpsons Good Little Cartridge). Judging the obscurity of the 7mm-08 Ackley Improved and it's small powder Gains comparatively the SGLC has it beat on all sides. The SAW is nothing more than a shoulder Angle change from the...
Folks are having a mental block with the entire Ackley Improved thing, RCBS did have one or more 30 degree shoulder dies they used to sell. Remember, Otto's 1st wildcat was in fact a 28 Degree shoulder, not a 40, and he made a two separate short magnum wildcats with 25 degree shoulders I...
According to my very non scientific math this Cartridge provides somewhere in the neighborhood of 71 Grains total Volume. If one was to design it as a 40 degree shoulder they would have even more if that's what you're after. I drew up that illustration from memory, as noted earlier you can make...
That is a question you have to ask yourself? The Illustration depicts a 30 Degree Shoulder. I'm fairly certain the Sherman is a 40. There is a whole world out there full of ideas and designs to choose from. It's not my design, but I like it. It's based on the do-it-yourselfer.
