and for the 375 RUM 300 gr. Barnes triple shock because of its high BC of 0.555.

You might want to hold off judgement until Barnes tests and gives that bullet an accurate BC, which should happen soon.

I mean that number is going to change soon. It'll be more accurate once it does.

Has anyone tried the 375 Weaver it is a 375-300 RUMImp.
I belive you can get a extra 100 - 150 fps over the 375RUM.

BJ,

YOu will not get that much velocity increase. If you compare the 375 RUM to the 378 Wby in same length barrels, the MUCH larger 378 Wby will only get you 100 fps more velocity.

The improved version of the 375 RUM may get to 40 to 50 fps more at the vary most. Variations in barrels will determine which would produce the most velocity, a standard or Improved 375 RUM. WHen the bores get this size, improving them, especially improving a RUM case will not get you much as far as increased performance.

Whatever the 375RUM does the 378Wby does it better if balistic performance is a concern. The belt is not a hassle. Being it's going into a bat, I would look into a Kahn with Kirby. More is a good thing when your going medium. If I was doing up a Bat, and I sure wish I was, I would be all over the 338AM. I have buddy with one on order and we can hardly wait. I would park everything else and use it on everything. It makes the 375RUM look a little anemic. Maybe you could have the first 375AM. I'm sure it has been discussed. Just needs a little demand to make it happen.

Re: What round to use 375RUM or 378Weatherby

Hired Gun,

Believe me, the 375 Allen Mag is sitting here in front of me on my desk on paper. This one has been just begging me to send the reamer print in for the build. With the right bullet, a 375 Allen Mag would give you everything the 338 AM would ballistically but with a significant increase in kenetic energy and frontal area.

Right now the only thing holding me back is a viable bullet. By that I mean a 380 to 410 gr ULD RBBT. Unfortunately, not good news from Wildcat bullets on those dies though so for the time being we are leaving things on paper.

No sence doing all the work to throw a 300 gr Sierra BTHP out there that will not even handle the impact velocity. SHE would be fast as hell though!!!.

If there is interest there will be a 375 Allen Mag here soon. Again, it is my personal opinion that it would be a better round then even the 338 Allen Mag and I think the 338 is about "it" as far as ballistic performance is concerned currently, even including the 50 cals.
