the wolf is more so made for AR's and the like instead of good bolt guns. and i wouldnt try anything but either v-max, sp, or hp rounds for any animal. some of the best factory ive tried was black hills 55 gr. sp. which is what i still shoot basicly. i shoot it when i want to shoot factory and i reload almost the identicle load for everything else. ive not had much luck with finding good ultramax stuff. and as far as the win 45 gr. goes its not bad stuff. i shot some and got a bout 1.5" groups at 100 yrds. if you go with cabelas stuff id get their 55 gr sp. its the cheaper of the "good" stuff. the vmax work well but they are more expensive and the sp's do just as well same with the hp's imo. so all in all if i was going to get factory stuff id go for black hills first then the cabelas bulk. if you are near one it would be betterprobably to just go get some seeings that freight is so much and then they cant give you the back order crap.
