I have been pleased with the performance of my two rifles chambered in .405 WCF, another "old" cartridge with some life still in it. Both my Winchester 1895 .405 TD and my Simson Suhl .405 DR shoot their standard 300 grain bullets (And NF handloads) at 2250 fps and 400 grain Weldcores at 2100 fps and both are very handy.

In fact, due to the combination of power and handy size, my 1895 .405 has become my favorite big bore stalking rifle and has taken water buff with 300 grain NF and Cape Buff with 400 grain Woodleigh; one shot did the job in both cases.

Red deer Hind for meat with Hornady 300 grain load.

PS Nothing against the "metric" calibers, I just do not need them.

The same for my 1886 TD .45-90. Modern application of a proven dated design which has yet to meet a critter it cannot kill.
