Wildcatters

A quick search shows there are plenty of reamer specs already done up...that kinda takes the wildcat design fun out of it...

That's true it does but it also checks all the boxes you want checked.

I have had several wildcats over the years because I bought P O Ackley's book when I was young. I have a 257 roberts AI which has a case volume not far from a 25-06 volume. ER Shaw 26 inch fluted barrel. I usually take it and my 270 AI deer hunting.

I like the medium action 25.284 idea, has it already been done? Is there a reamer made already?

Also is there any improvement on case dimensions that could be made? The 30 degree shoulder looks good and body taper looks good already so it would be pretty much neck it down and go...no fire forming really.

I believe GLTaylor on here did a 25-284 improved. Maybe he will chime in.

Take a 284 Win, but shorten the neck to .227 and push the shoulders to 40* with .485 diameter.

Call is the 25 Gibbs-Sherman-AI.

Might get a little sticky in the chamber if you really over-pressure it, and might have to use a ball powder.

If you want a medium action rocket get a 25 Max.

The idea of using cheap and plentiful 308 cases is a great idea. I would for sure make it an AI version to maybe gain 5 grains of powder. I make 243 rounds out of 308 range pick up brass. I first resize/decap it to 260 rem. Second after wet tumble with steel media I then anneal the brass. Third I run them on my RCBS machine to inside and outside true the neck because the neck brass gets thicker as you run it down in diameter. Then I run them through a 243 resizer die.

It's a lot of rewarding work to pump out hundreds of high quality sorted same case volume trued brass. You will have to do something similar.

I'm a long barrel fan with filling the cases with slow burning powder. I can under load a long barrel and still beat the velocity of a hot rodded short barrel. It makes everything last longer. Over bore rifles have limited barrel life and I gave up on bragging rights long ago when I was on my third barrel burning 120 grains of powder ever time I pulled the trigger.
