Stop in for a cup of coffee

Congratulations!! Wanna rack your brains for your opinion. As much as I love my Grendel, I’m thinking of upgrading. Possibly to 300 Win Mag or 338 Laupua Mag for deer hunting. Bit overkill but I want to also be able to go out west to a buddy’s place in Wyoming and hunt Elk.

I shoot leftie so most bolt guns are out, is there a good semi rifle for this purpose
