I'm across your border to the West where Gov. Dayton rules. I shoot a 270 under the same conditions as you folks do. I reload and prefer the Nosler 130 gr. Ballistic Tips for my 270. Nosler's have never let me down while sitting up off the ground in my stand. When I'm Still Hunting on the ground. I use my 300 Sav or 32 Special with the now discontinued Winchester Silver Tip bullets. Basically an open tipped bullet. Not much difference than Rem Core-Lok's or Federal Soft Points From my experience. I've never seen a bullet fail to do what it was intended to do so long as it was American made. I'm a firm believer its all about shot placement. Than practice more practice and getting familiar with your firearms ability and its quirks too.
