[QUOTE="Greyfox, post: 1061083, member: 10291"] Your velocity reading using 51.5gr of H4831sc is the same as I get using that charge in my Savage. It's possible that your chambering is off. What is the COAL of a round that is loaded to the lands for a 140 Berger VLD using Lapua brass. This runs 3.19 in my Savage LRH in 6.5-294 and 3.185 in my Cooper. Both generate 2940-2950 velocity and no pressure with 53 gr of H4831sc. The other check is your headspace, which if off, can be easily adjusted with the Savage by turning the barrel. The headsace of a fired Lapua case compaired to a new Lapua case should be .005-.008" longer, and sized .001-.002" less than the fired length. If these dimensions check out OK it's possible that the issue is with the bore. iMO. [/QUOTE]
