I am working up a 178 amax load for my rem 700 vs in 308 win. This rifle has always seemed to prefer velocities at the low end of the spectrum. My most accurate loads are generally my starting loads. It seems like the more powder I put in, the larger the groups become. I am working up this load because I would like to work my way out to 1000 yards this summer. Up until now I have only shot at 700 yards and under.
These primers are cci200. load was 43 grains of varget. 2.832 col (to fit magazine)
The bold lift was not stiff and there are no extractor marks. I don't have a chrony so i don't know the velocity. I have always borrowed a buddies chrony for my drop charts. My ? is what are acceptable pressure signs when working up faster loads. Obviously the people getting near max velocities don't have perfectly rounded primers to show for it. What is you personal limit when it comes to pressure signs?
The cratering is not as bad as it showed up in the pictures. Just a tiny ridge you can feel with you fingernail.
The load I have been using for my long range shooting up to this point is a 165 sst traveling at 2400 fps with 38 grains Imr 4895. When I get the velocities up around 2600 fps for this load my groups go from 1/2-3/4 moa up to 1.5 moa. This seem to be typical for this rifle. Any suggestions?
