Hey all. I am looking to start another rifle build off either a savage 110/10 action and I am undecided on which caliber. The only goal I have set is the ability to take a deer to 400 yards (no further and 99% of the shots will be under 200 yards). I currently own a 7mm rem mag for all my extreme ranges (>400 yards). I have a 3006 shooting 180s packing a whallop on the shoulder (my reloads are running HOT!!!) and my wife has a 243 that I shoot occasionally. Yes the 3006 and 243 are both capable of taking deer at 400...I just want another project for the winter :) I do reload so factory ammo is not really an issue BUT finding reloading components is a plus so I would like to avoid calibers where you MUST neck size or "fireform" brass because no one sells that brass or any wild cat extreme calibers. what do you all suggest?
