Ok, hopefully I got everyone’s attention with the subject. I'm looking for some input on an idea I've been having for a cartridge for a DR project I'm about to begin. Now I'm interested in all feedback whether you think it is a good idea or the dumbest idea you ever heard. However I ask that either way you give an explanation of why you feel that way.

I sold the 9.3x74R DR I had built. So I was planning on building another. However I started thinking that something with greater bullet availability and greater range in size could be fun. However I don't honestly need anything bigger than the 9.3x74R because I pretty much am limited to North America hunting for the next decade or so. Thus I need to either go to 358 (basically the 400/350) or 375 calibers for more bullet availability. I also wanted to keep this wildcat on brass that is readily available. I also wanted to keep pressures below 40,000 p.s.i. Probably even lower if possible. So my thoughts are as follows. Make a 375 wildcat based off of the 9.3x74R case. I chose 375 because using bullets of equal weight with the larger bore should reduce pressure. It will also give me a reference to use when loading. Then I basically looked at the case and decided to use the larger shouldered style of the case, basically just necked up to 375 but more shoulder than the 9.3 case. In other words it reduces some of the body taper but isn’t close to “minimum” body taper. After some playing at the reloading bench I come up with a case that is approx 12% more case capacity than the standard 9.3 case. Now I figure I can push a 300 grain bullet at about 2100 FPS and still keep pressure well less than 40,000 p.s.i. However the main idea would be to run about 260-270 grain bullets at about 2,400 FPS. However if I was so inclined I could drop down to 200 grain bullets for a reduced load.

Anyway that’s my thoughts. Obviously it isn’t very much different than the 9.3 case. However gives the advantage of using readily available 375 bullets.
