I bought some lightweight but insulated gloves from Walmart that work good with the Omega. They probably are not good enough for 0 degrees but work fine at 25 to 30. I live in Arizona and usually get snow mixed with rain when I get to hunt elk. I shot an elk with a 300gr. Hornady SST in a Harvester sabot (can't load Hornady with their own sabot in my rifle, they are too tight). Bullet passed completely through chest cavity at 100 yards. I have also had similar pass through with aero tip Powerbelts 295gr. I am considering switching to hollow point for next year. The pass through did make a good blood trail but I only got one lung on the first shot so I had to follow the trail for about 1/2 mile before I caught up with the elk. I think for deer you will get pass through with almost anything unless you hit heavy bone. Unless you are expecting to shoot very long distance I doubt that the aero tips do much for you other than limiting the expansion which I do not think is a good thing on deer. My opinion; I'm sure you will get others.
