I have two buddies shooting the .277 Wolverine, I know they both like it. They love shooting 90 gr Gold Dots for everything. It's probably one of the best performing bullets for the Wolverine.
However, my one buddy hates me for it. I bought a used 16" HBAR barrel, and I decided I didn't want to get invested in it. My buddy showed interest and I mailed it to him and said Merry Christmas in July! He said a free barrel never cost him so much.
I just decided it wasn't going to do anything my 5.56 couldn't handle. Besides my yearly OK white tail hunt, an AR-15 just isn't my go-to mountain hunting rifle. So I shoot mainly prairie dogs and coyotes with the AR, which is why I've never really had anything else than the 5.56 until I built my .300 BO pistol.
One of my buddies with the Wolverine also built the .358 Yeti from MDWS. He likes it better than the Wolverine. He says it just his harder and puts things down quicker for deer and hogs.
