Just what we need Outfitters telling us what to use on Elk. In most instances they are on the money. This guy is dead wrong if your dead familiar with the 175 grain then bring it to the dance. That is absolutely a perfect choice for your gun provided it shoots it well and apparently it does. I have had on and off problems with the 160 partition in 7 mags and 280's seems that 280's like them better for some weird reason. Use the 175 and tell the outfitter to leave that one alone
