Benny, my son and I have used our tang-safety Ruger 7x57 on 5 elk and numbers of whitetail deer. All were shot with a handload using the Remington 150 grain PSPCL pushed to 2800 fps. Performance was excellent and we have not lossed a single game animal hit with it. We have not used this rifle on game past 200 yards and in our neck of the woods don't have much need to.

Both bullets you identify have excellent reputations in general. In fact, due to construction differences, I would tend to think at least the A-Frame would be even better than our Remington. Not having used it or the Woodleigh, like you I am curious about both, but I would tend to be most interested in the A-Frame 160 pushed pretty hard for exactly the reasons you identify. Having said that, I have about 600 of the Remingtons here and will continue to use them without hesitation till they are gone. They are cheap and allow inexpensive practice and as with all calibers, shot placement is key, and the 7x57 is easy to shoot well. We don't use this rifle for a primary rifle but more as a spare, but a spare we are totally confident in. One of the elk I shot with it was taken on a crystal clear night under bright starlight in snow from 98 long paces, I having made a 1000 meter stalk in white camouflage from the house across one of my hayfields {legally shot after dark on a depradation permit}. I mention it because for some reason that rifle has been used for some of our more memorable hunts.

Let us know what you decide to go with!
