Interesting. Where could someone find these published notes? Also, was Weatherby using an experimental version of the .308 Win in the late 1940s or are you referring to .308 bullet diameter?
I have never hunted with a .300 Weatherby but have a couple and like the round. Mine get 200--250 fps more than my handloads in .300 Win Mag with weatherby factory loads. My .300 Weath Ive shot the most is getting 3420 fps from 165 TSX factory loads and 3250-3300 with various 180 weatherby factory loads. I also don't think I've ever shot a group larger than 3/4 MOA with that rifle and most have been significantly smaller than that and therefore have never shot a handliad through it.
It fits ne well too. Maybe it should go hunting some day.
I've hunted with Wby and Winchester .300's, never a .30-378, although I've been there and seen them used. My current .300 is a Win Mag and I feel it's about all the .300 Mag I want. I find myself using smaller bores for WT and Pronghorn and have bigger stuff for Nilgai, etc. Just don't use a .300 Mag as much anymore.
