Incredible cartridge! I shot a half inch group with factory Weatherby ammo(115 gr Nosler BTs) in my 700 CDL SF. I showed the group to a very knowledgable reloader.. He said he might be able to beat it. Well I gave him 2 boxes of empties. 2 weeks later he dropped off both boxes loaded with 66 grains of H4831 using Fed 215M primers. Bullets are 117 gr Sierra Game Kings with an overall length of 3.250. I shot three shots. All three were in the same hole!!! I told him to load me up 3 more boxes! Killed a deer this past hunting season. Dropped in its tracks. Nastiest most accurate deer round I have ever seen.
