I own one of the Winchester Model 70 XTR bolt guns from the 80s. It needed glass bedding but shoots OK. Long throat and 81/4 twist. I mostly use Nosler 160 Partitions and their old 162 grain solid base bullet, which I like a lot and still have a couple hundred of. Mostly use IMR 4350, 4831, R22 (had a lot of it too), Now using some 4000 - MR. Have killed three bull elk with one shot each. Wound channel about the same as 150 grain 270 (which I have killed several more elk with). Maybe the wound channel is a little less bloody. Very good deer gun. Interestingly, I get my best accuracy with Speer 145 grain Hot Cores and W760 or H414, fine for deer at normal ranges (under 300 yards). I have never shot an elk over 300 yards away and only shot at a couple of deer over 300 yards. The 7x57 is a very nice light sporter weight rifle choice. I also think the case capacity is better for 160 grain bullets than the 7mm-08, good as it is.
