Considering your location & possible uses, I'd even try a 220 Hornady FN. The .235 Speer SRN, might easily prove too tough at those lower speeds, considering it expanded poorly when driven at 2,000fps from a .375 Winchester M94 (Fadala's test).
The 220gr. Hornady was designed for the .375 Winchester and the ones I put into moose, showed wonderful expansion, weight retention as well as side to side penetration which included a shoulder on the impact side. Too, there is a 200gr. Sierra FN that might be interesting as well. I am wondering if the lighter bullets might give parallel separation to the barrels & lower impacts? Just a thought.
This is fun. It's even better is the speculation bears fruit.
