I have this exact rifle which I use in a MDT XRS (the same chassis is also used for my other 110 with heavy barrel in 308). Like others have said, it is not a blinking rifle. I reload which negates the specific problem sourcing 300 WSM ammo.
You paid a very low price for the kit though and it is a very capable hunting rig for larger game. If you can afford to buy something in 308 or 6.5 Creedmoor, you would have more fun shooting and practicing technique with that and it could also serve hunting deer, black bear, etc.
