No sir. AI is an Ackley Improved. It’s a 375 H&H, with much of the body taper blown out, and the shoulder angle sharpened……resulting in more case capacity. It’s very similar in performance to the old .375 Weatherby (not the .378 Weatherby) which has the typical Weatherby radius shoulder.
I’m presently running Barnes 250 grain TTSX’s at 3130 mv. Quite a few years ago, I gave up on Barnes making a high BC 270 grain bullet and bought a bunch of 250’s, developed a great load……then the bring out the 270 LRX. Really want the heavier bullet…but simply have way too many 250’s to start with the 270’s! memtb
I knew what AI meant... I have a couple myself. I just wasn't sure which 375 you improved. A 250 grain bullet at 3130 is impressive for sure.
