I'm looking to build a long range hunting rig and cannot decide which caliber I want to go with. My options are the 300 Norma, 300 RUM, and possibly 338 Lapua. I understand the two 300's mentioned above are bbl burners but this would be a hunting setup so it's not like I would be shooting all the time. I will be hunting whitetail deer @ a max range of 600-700 yards. I plan on hand loading but that will be a project down the road. So for now, I'd be starting off with factory ammo. I understand factory ammo is limited given my selection of calibers but seems like there is still a decent amount of options out there. I'm trying to weigh my options between all three calibers but I am having a hard time deciding which way to go.
Weight is not necessarily a factor. I don't mind a heavier gun because we don't have mountains in the south!
As far as the actual build/specs, I am between a full custom build or a factory build, i.e. Christensen Arms, in which I am very intrigued by at the moment.
Now, before anybody says anything, I know what you're thinking. Could I achieve this goal with a smaller caliber such as 6.5, .308, 30-06, or 7mm? Yes, absolutely. However, I am and have always wanted a big bore hunting rig so my mind is made up that this will be the direction I'm going.
With that said, any advice/opinions would be greatly appreciated. I'm open to all comments and suggestions.
Thanks!
