[QUOTE="RDM416, post: 457077, member: 3745"] Icanhithimman, I'll get a pic of the rifle posted tomorrow..... it's too late tonight to go back down to the basement, take a pic....... jmden, I think he used a traditional steeper angle throat, but I am really not sure. With both my Khan's he used a throat reamer to make the throat longer than the standard Kubla Khan reamer. The principal reason he and I talked about was so I could seat the long 300 SMK farther out to gain additional case capacity. Maybe Kirby will run across the thread and answer these more detailed questions on the throat lead and angle. I just have not gotten that far into the specifics with him. I give him the major requirements, send money....... wait...... he ships me a rifle and it shoots real good.:D My older Khan built on a Wby MK V action was built with the same reamer and throated the same. I have been shooting the Bergers through it at 2875fps using 102 grains of Retumbo. It will shoot 1/4 moa with only a VERY occasional round dropping out of the group. I may try loading some down to the same velocity for this rifle and see it that is it. I may just be seeing the same thing most everyone else is with the Bergers at higher velocities. I'm still not sure it was not just me, I have been hunting for the last few months rather than shooting so I have not had a lot of trigger time lately. As I said before, if you take away the two fliers out of the last two groups and overlay them, it would be a sub 1/4 moa 4 shot group, maybe I just blew it with those two shots. I'll keep testing, the averages will start to stack up one way or the other after a few more rounds. [/QUOTE]
