Well i just got through building my first 25-06 a.k. This is one of many different calibers that me and my father have built over the years. Its an L.A tang safety Ruger action with a 26" shilen 1-10 twist. I've always been a lighter bullet is better kinda guy but my 25 A.K loves 58 gr accurate 4350 with a 85 gr nosler varminter at speeds of 3680. If you have never loaded for an ackley befor my rule is start with a regular load for that cartridge for fireforming and stay away from nickel brass. After fireforming start with the top load for the regular cartridge and work your way up,The point of building an ackley isn't getting more speed but to get the pressure down if you wanna get more speed then go with a weatherby or different round all together but i guarantee the ackley will be a better shooter. Either way you feel I'm an ackjley man for. life. Feel free to. ask any questions.
