I use 67gr of AR2208 behind the Taipan 220gr FP in my 375H&H as a Boar, Deer and Rabbit round.

I have worked this out on a reduced load calculator as getting around the 2800fps ball park or about the same performance as a 338win mag just with less kick.

it is a very accurate load in my rifle and very easy on the shoulder, it is also the same load as I use behind the 270gr Woodleigh PP for the bigger stuff.
