375 H & H Improved ?

[Guest]

Anyone got experience with the 375 H & H improved ?

If its like the other improved cartridges, I could just get the chamber in my rifle brushed up?

What`s the improvement ? Only speed, or for instance lower pressure, better accuracy ??? :?:

I would think the improved case would blow out the case size and change the shoulder angle giving you 100-200 fps improvement.
What is the difference between the improved and the 375 Weatherby?

Performance wise, there is very little if any differance between the 375 H&H AI and the 375 Weatherby. The load data is virtually identical between the two ... depending which data you use. Realy, the only difference between the AI and the Weatherby is that the Weatherby has the typical radiused shoulder and the AI is the typical 40 degree shoulder angle. Both fire form using 375 H&H loaded ammo.
