Energy is like top 378 loads but I think he haa slower twist, which might make up the difference between 35 and 375 bore.

Now THAT is one hell of a cartridge!!This is also known as the 350 Wells Express,exsept I think the Wells used a different shoulder.

I might have to have a Ruger #1 done up in this number.It should shoot a tad flatter than the 378,plus bullets would be a bit cheaper.A 225 grain Ballistic Tip at about 3300 FPS would shoot quite flat.
