Re: 7mm Rem Accumark Range Report.
Does the accumark have a short magazine? In my Rem 700 I seat the 168 berger just into the lands and still have plenty of length left in the magazine.
I am using 73 gr H1000, Federal 215 primer, Federal case, getting 3087 from a 26" barrel. Groups around 0.5 - 0.7 inch at 100yds.
After you have tried upping the powder charge, try varying the primer. I have heard that using a non-magnum primer can reduce your group size ( not sure if rem 9.5 primer is magnum or not).
