HERETIC!He would be laughing at the 40 S&W
Mr. Keith was fond of the 33 calibers, for certain. I had a Win 86 TD FWT in 33 WCF for a time, but it wasn't terribly accurate. 3.0"-3.5" at 100 yards was about all it could manage with either the 200 grain Hornady soft points or the 210 grain cast RCBS FN GC. The castings did shoot right with the J-words to 2100 FPS, though. I don't know whether a solid-mount barrel in an 86 would have shot better or not. I think the 338 Federal, 338-'06, and 338 Win Mag are all fine calibers--and the 338 WMs have been quite accurate for me (2 bolters so far). It is one of the belted magnums that makes sense, and isn't completely over bore capacity. A 338 Federal AR-10 is a very intriguing idea.If he had a black rifle, it would be an AR-10 in .338 Federal. He helped design all those “OKH” cartridges in .333”, .334”, and .338”. It seems that he thought that 1/3” was the sweet spot for modern bottle neck rifle cartridges.
