Most of the factory rifles won't accept the factory length of a SAAMI 300 PRC. Don't assume you can rebarrel just any random rifle. Howa 1500 has the least expensive entry to shoot 300 PRC and im pretty sure it could be reamed out to 300 ultra mag or 30-378 weatherby later.
338 win mag, 35 Whalen, 9.3x62 and 375 h&h/Ruger are great calibers. I have been seeing 375 h&h still available but only the more expensive stuff. Good thing is you won't spend a day at the range shooting it.
I live in AK and have a 300 PRC. Factory ammo is nonexistent currently and it doesn't even seem available down in the lower 48. Reloading supplies aren't exactly very plentiful either at the moment. The one downfall with using a factory rifle is not many rifles have adequate magazine spacing...

300 WM is hard to beat. If I were to start with one rifle it'd be a 300 WM with a 1:9 twist just for a bit more capability. I took a moose in 2020 with my tikka 300WM. I wouldn't hesitate to take it on any hunt with exception of Kodiak which I'd take my 338 or 375.

I wonder where they draw the line at for being "related to firearms." If you wanted to you could in theory tie all optics purchases even things such as spotting scopes and binoculars into the same boat. I know I will be purchasing some hammer bullets in the future, just haven't had time to get...
I relocated from Florida to Anchorage area last year, was a beautiful drive. I'm originally from Upper Peninsula of Michigan and retired from the Air Force in 2017. In addition to having your paperwork in order for taking your guns, realize that if you're going through Canadian National Parks...
