Hey,
My guide recommended a 270 or similar. I've talked to a few people who say that's way over kill for a cat. The guide also said I could use his 30-30. So he figures 30-30 is plenty. I do have a 686 no dash and a 657 no dash that I could take but from what you guys are saying, the 280 is going to be too much. From what he has said to me, we will be using trucks, snow machines, or possibly atv to get into the general area then let the dogs do their thing. Depending on how far, more atv/snow machine action and a hike in to the treed cat. I'm leaning to the 30-30 not only for nostalgia purposes but also because I want to keep the hide, and I predict the 280 would have an explosive effect. I shoot 160 accubond out of it at about 2950fps. It anchors anything I've shot with it, including a 375lb southern Oregon bear. Now to throw another wrinkle into this... maybe my cz 527 in 7.63x39? My buddy coming along is taking his great grandfather's Winchester 71 in 348, with some very downloaded rounds we are working on. Talk about nostalgia!!!
