[QUOTE="101stCurrahee, post: 1894168, member: 111731"] Thanks for the replies. I'm going to try and fill in the missing info. That really sucks, and I'm guessing it's some sort of defect if you've noticed those issues. Primers are CCI 250s. My muzzle velocities on my last test are: 76.8- 2783, 2956, 2898 77-2807, 2930,2898 77.2-2879, error, error 77.4-2923 ,2783, 2749 I started a ladder test at the lowest safe charge weight and increased until where I am now. 76.8 gave me the "best" group although it's still 1.5-1.7 on average. I stayed here and played with the 0.2 increments, but in either direction it's back to huge groups. I also tried backing down the other way a grain or two with the same results. I can definitely start the ladder test all over, but I'm thinking it might be a waste of time given my last results. I'm using a NightForce NX8 4-32, with NF rings, that was installed by a smith. It is not touching the barrel or mount. I have tried doing these tests letting the barrel cool and not. Same results. I do not allow rounds to sit in a hot chamber. I have let a buddy shoot it as well as using a sled to take out as much human error as possible. I guess my next step is to go buy a box of quality 300WM, run it through the chrono and see what the results are. [/QUOTE]
