[QUOTE="Razer, post: 322294, member: 19141"] Hi guys! I have some questions about my reloading data. I am new to using a crono and don't have a lot of experience fine tuning my loads. All taken at 100 yards Rifle - Remington 700 300RUM Sendero Brass - New Remington Primer - CCI 250 I have 2 different powders used, the first is RL-25 with 208gr. A-Max 90 grains 3023 ES is 27fps 3003 3016 3009 2996 90.5 grains 3044 ES is 14fps 3044 3037 3030 3030 91 grains 3051 ES is 35fps 3058 3030 3023 3051 91.5 grains 3058 ES is 42fps 3072 3096 3072 3100 On all of these loads it was easy to open the bolt, there were no ejector marks on the brass, the primer was a little flatened. Second set of data using Retumbo and 200gr SMK 91.5 grains 3023 ES is 21 3030 3037 3023 3016 92 grains 3100 ES is 22 3086 3108 3086 3100 I still have to test 92.5, 93, 93.5, & 94 with the retumbo and 200 SMK Same as before, bolt was easy to open, no ejector marks, primer was a little flatened but not as much as RL-25. My question is, what should I do with this data, what would you do with this data? Is the extreme spread ok? The groups were better with the RL-25 (1" - 1.25"), they were not good with the retumbo (1.5: - 2"). Can I keep going and up the powder looking for my max velocity.
