I know a lot of hunters use the 140 and 150 grain Remington Core-lokts in 7mm Rem Mag for deer hunting and do quite well with them. I was at the range the other day, and ran across two shooters sighting in there 7 mags useing 175 core-lokts. I ask what they were hunting and thet replied...deer. I personaly like the 140's for deer but hard to find around here so I use the 150's. I always thought the 175's were thicker jacketed and made for killing Buicks. Has anyone used the 175's for deer? Will they expand as well as the 150's or 140's in the core-lokt? The reason I'm asking is they shoot darn well in mine and was thinking of useing them myself.
