[QUOTE="Capt RB, post: 1836371, member: 85987"] In my 270, typical magneto speed readings are 3140,3140,3139,3140 and 3141. In my old creedmoor I struggled in load development because everything from 2820-2875fps shot into a hole and had less than 15fps es for 10. First load was 2855fps @ 2.855coal .003 off. Es 8 sd 3. After 300ish rounds I found that backing off . .3 .018 off had better vertical beyond 500 6es and sd of 2 for 10. I backed off a bit more and 20 shot groups looked like good 3-5 shot groups with better barrel mirage characteristics over the string. In my 65/06ai 147's @ 3120 and 150smk's @ 3110 with plenty of margin another single digit ES. 7mag which I have not played with much due to what that rifle is however, 168 bergers @ 3090 into .5" @ 200 is going to get it done. That's as far as I have worked with a 7mag so far. I'm sure there are some finer attributes for a 7 but I don't have the desire to play with that one being a 700P at this time [/QUOTE]
