Regardless of how it shoots and I bet it shoots well - I'd rebarrel to 7 wsm as it's a better mousetrap in that wrapper.
Inside 800 yards it won't make a difference. And at least 300 WSM brass is obtainable. Sort of.
I'm sitting on a PILE, 4 figures worth, of 7mm bullets and exactly zero 30 cal bullets. Big motivator for me and there's nothing I've ever done in the past with a 30 that I couldn't have done with a 7 too. Why I'd do what I said I'd do.
This thread isn't about you, what you want, or what bullets you have. It's about the OP's new rifle. A 300 WSM. In the middle of shortages everywhere you and the resident narcissist recommend re-barreling a perfectly good rifle chambered in a round that has brass, bullets and ammo available to a round that has a severe shortage of brass and factory ammo.
Brilliant...
