[QUOTE="OzPete, post: 563583, member: 35697"] Hi Bryan, I am using a DSR-1 and the 300 SMKs. I have tried the Lapua Scenars and Lockbase 250's over three different powders. Every single one has been well under the tables velocities. My current load of 92 grains VV N570, 300 SMKs is 0.3gn over the tabled VV max load of 91.7gns. VV claims 2710 f/s. I am getting 2582 f/s and showing the first signs of pressure. The bolt camming on a few rounds was a little tight so I will back off to 91.7 and stay there. This load is the closest I have got to the VV tabled velocities (4.7% low). Not too bad really, until you consider than VV use EXACTLY the same test barrel as the DSR-1 is fitted with. The question is "Where the hell do they shoot these numbers? On the top of Mount Everest?" My conclusion is that the numbers are pretty much stacked to support the hype that this caliber has generated. The rifle/load accuracy is extremely good. The attached photo was shot using just the bipod, with variable low cross winds. I am a long way out of practice, so I think I can get a bit better. [/QUOTE]
