Hey everyone, just got a few questions...
I just bought a new Savage 116 FLHSS in 300 win mag because i had my 308 rebuilt and it is much to heavy to hunt with.
For my .308win, im shooting 208gr a-maxs over 48grains of RL17, im not sure of my velocity because the first chorny i shot it over gave me a velocity of 2850, with a ES in the 40s... i know that chrony was fast, obviously.
Then i fired though another and got a reading of a pretty stable 2610, this is a little slow from what others have been getting, only difference was the load i fired though the first chrony was 20thou off the lands, and ones i fired though the second chrony were just touching the lands. what can i try to bring down my ES? switch primers? i was used once fired neck sized brass, and im pretty **** anal about case prep and weighing charges, so doubt that was the problem.
Second, my fired cases have three ridges on the neck after being fired... i turn my case necks to .012" to clean them up some, since im using winchester brass, the ridges are vetical (along the axis of the case) and about .002" thick and quite wide, you can see them apon visual examination.
What could be causing this?
Thirdly, how can i accurately measure the COAL of my cases? the A-max's tip makes measuring from tip to base reading rather erratic... any ideas without buying a ogive measuring tool?
and finaly, any powder recommendation for my 300 win mag, im in highschool and can't go out and buy 4 different powders to try and then just leave 3 standing around that arent working. What would be ONE to try to start with. Im going back and forth between RL22 and H1000... RL22 is quite temperature sensative and H1000 gives little less velocity i believe.
Sorry for the massive post and thanks for any help!!
