if you are talking about the 235 then they are too hard for the 375 win. The 200 grain Sierra FN is great!
Speer didn't think so when I talked to them last week and suggested 1,000 ft-lbs (1,375fps) for deer and 1,500 ft-lbs (1,517fps) for elk.
In any case, I now have two boxes to play with. Will try them in water jugs at different velocities.
My rifle loved the discontinued Hornady 220g. I like the velocity I get with the Sierra 200g but the accuracy is not as good.
