I have been hand loading for .308 for about 2 years and recently purchased a new Remington 700. I'm in the process of working up a load and have been getting sub par (0.8-1.1 MOA) results in comparison to my old Remington 700P (0.2-0.6 MOA). Other than the fact that I'm using a different rifle and optic I'm trying to eliminate possible causes for the poor performance in the hand loaded ammunition first. It shoots factory Hornady 165 gr TAP ammo really well at 100 yards (~0.5 MOA). Last year I used up all of my CCI #200 primers and purchased Winchester Large Rifle primers.
Are CCI primers necessary for small groups? Should I expect sub par results from Winchester primers?
Here is my current load data:
Lapua brass full sized
Winchester large rifle primer
Lapua 155 gr Scenar
Hodgdon 8208 XBR - 45.2 grains
I know there are all kinds of different variables at work here but I'm looking for information regarding a comparison between CCI and Winchester primers. Thanks.
