No doubt. I was remarking off "arm chair expertise", and remember a discussion on A R where 'experts' were disparaging the .416 Chatfield-Taylor as too weak at approx 2,100 fps while in different threads the same 'experts' claimed the .450/400 was deadly(!) at similar velocities.

Different people using different loads, rifles, powders can get quite different results sometimes. And your expertise is hands on and real. Good to read of the much better velocities.

I came close to getting a .416 Chatfield-Taylor in the mid 1990's, when Brian Harre of NZ offered to build me a takedown rifle in .416, as well as .338 Win Mag and 7mm Rem Mag. Three barrels and forends. Using a Win M70 rifle as the platform. Never sourced a suitable controlled feed M70 and the project evaporated. Would have been a useful system. Instead many years later acquired my Mauser M03 with barrels in .404, 8x68S, 6.5x65, and .222. For the same sort of concept and world use.. So far my .222 has had the lions share of use, but planning the .404 and maybe the 8x68S will get a run this year in the Top End.
