Has anyone here used the 6.5 140 SST on Elk? I've done some searches here and found a few posts about deer size game. I'm thinking about using my .264 WM this year. It'll have a 28" Broughton 5c barrel. I'm aware of the 2 bonded 6.5's (swift and nosler) which are both 130 grainers. I would prefer a 140 grain pill. I like the idea of the SST because of its high BC and assume its performance at long range would be decent... but with the chance of a short range shot I'm curious how it will hold up. Any real world examples?
