I have to guess at the chamberings and the number of head. The smallest was a 22/250. , the largest was a .375 H&H. I personally always carried a 30/06, .270 win and 25/06. I gets blurry, separating the elk out otherwise. I worked for various outfitters as a guide as a 20- 30 year old and sporadically since.
Those were the Weatherby mark v days. They were zero'd at the factory and tightened up at camp. I still despise them those inaccurate fire breathing things..Just my little old opinion
