I’m torn between what cartridge to chamber a custom rifle in. This will be a hunting rifle and primarily for Whitetails, Black Bear, Mule Deer and Antelope, with the intent of doing a few Elk hunts. This must be able to accurately shoot past 1000 yards though. I realize there are a lot of cartridges that fit this bill and can effectively take down any of the above animals. However, I’d rather not shoot a 300 wm or other hammer if I don’t need to. I’d also rather restrict my distance on Elk to 700-800 yards as well as I do t plant on doing a whole lot of Elk hunting. Accuracy (easier to tune and load), barrel life, etc. are of high importance here. Unfortunately I do not have much experience with most long range calibers/cartridges and mostly shoot .30-06, .308, .270. I have a 6.5 Creedmoor which I shoot to 1000 yards but would not shoot any of the above other than possible Antelope at that range (would have to research that even). So I am looking for recommendations from you guys. I have considered 300 PRC, 28 Nosler, 7mm WSM, etc.. I think the .277-.284 caliber cartridges probably fit the bill but don’t hear too much about the .277’s anymore. And the 28 Nosler sounds like it has horrible barrel life.
