Oh well, here goes....
I got to admit I've never seen an elk killed with a 140 Noz BT out of a 7mm, but unless the 140 grainer is a LOT more robust, and sprinkled with more Pixie Dust, than other BT's..........
....the BT would be among my last choice in anything with a MV over, say, 500 fps
I've killed or witnessed the kill on at least a dozen elk in the past 25 years with BT's--from my personal experience with early production BT's out of a 270 to recent years guiding and witnessing the effect of BT's with 7mm's, 30 cal's, 338 cal's, and a 35 Whelen--ALL of them resulted in a elk race to one extent or the other. Not to mention a couple races with muleys and one pronghorn.
It's actually a bit of a joke with some guides I know; If the client is using BT's, we wear our track shoes........
In light of all the other good bullets out there, the BT is waaay too frangible.
A TSX in 150gr (preferable) or a 140.
My first choice is going to be a 150 Noz Pt, or a 140 Pt--Partitions in the medium or heavyish weights still seem to perform the most consistently across the widest range of velocities, with as good of penetration as any.
