RE: caliber or bullet weight
I believe alot of people get into the theory of having to have a new rifle to go hunt a new species of game. And most do this right before the hunt. Which leaves them little time to prepare and familarize themselves with that particular rifle and how it shoots. Especially scope adjustments and trigger pull. Most would do themselves a big favor of taking what they use on deer to go hunt elk or similar animals. The state put the minimum calibers in the regs for a reason. With good shoot placement and range capabilities of the rifle all will kill just as fast and as clean. But I do understand wanting to purchase a new firearm for things maybe as big as moose or brown bear. Maybe not so much on moose, but a brown bear one would hope a larger bullet even if placed bad may be enough to save ya butt but I doubt it. It's all shot placement nothing else matters. Not caliber nor weight of the bullet.
