Sorry your season hasn't gone as you expected. Neither has mine, but as long as we can get out and hunt it isn't that bad of a season. There is always next year.
Yea, I have a 300 SAUM in a Model 7. I love that round. It is good for all but the very dangerous grizzly or polar bear. I shoot the 165 Sierra gamekings and the 150 Nosler accubonds. I hunt whitetail with the Sierra's and elk, bear and muley's with the accubonds. You can even load the Hornady varmint loads, I think they are 75 or 95 grains, and get 3700 fps to hunt yotes with.
Good luck next year!
