I have never gone up to the 175 gr, 160 shoot well in my mod 7 but 150 nosler ballistic tips just shoot excellent groups. On deer I haven't killed one over 200 yrds yet that is about the longest shot I can take around my area in Pa. I have killed 2 does and 1 buck with it. Right now it's on lone to my son who wants to use it for a pig hunt. The only experience I have with rem bullets is in 308 cal, so I'm not sure on the expansion, it sounds like it may be more ment for a 7mm mag or 280 velocity, That is a long bullet to get in the my mod seven magazine area if it was crimped on the cantalure.
