I would think the Whelen and 350 are ballistic twins, and very similar capacity?

Fotis, nice set up. Yes, I know you are not as hot as the South, I did look up temps your way. During hunting season if you see a drop in 30-40 degrees or more, it might affect performance. Not sure about the powders you are using, whether they are temp sensitive. I would say 2800-2900 is a good place to be based on some calculations I ran. You are in good shape no doubt for whatever you run into.
