I owned one for a few years… I enjoyed it a lot… identical ballistics to the 416 rigby and 416 rem mag, but in a standard action, with just a tiny bit less felt recoil (although at greater chamber pressures)…
Mine was both accurate and reliable… I only sold it because after gravitating away from 375 h&h for a while, I came back full circle and decided that as a client and predominantly buffalo guy on the DG side of the house, that the 375 H&H was both what I personally liked best, shot best, and shot the most of.. so the Taylor was spending more time in the safe than it should… and I thought someone else could likely get better use from it…
If you’re a reloader, they’re easy to work with… 416 Taylor brass is available (although not exactly plentiful) and necking down 458 win mag or necking up 338 win mag is easy enough as well… projectiles are easy to come by.. powders for the Taylor are easy to come by, etc…
If you don’t hand load, I’d advise that factory ammo is very hard to come by these days… the only thing I see reasonably regularly is Norma solids honestly… it’s been a few years since I’ve seen any factory sorts for sale anywhere…
