GreyGhost85 Report post Posted December 4, 2015 I like to start with .030 or .040 off the lands. I think Berger recommends .040 Share this post Link to post Share on other sites
rcdinaz Report post Posted December 4, 2015 GreyGhost is right (kind of) here is the link I can't paste the link for some reason... 0.01, 0.05, 0.09, 0.13 were the recommended "hunting" starting points for testing VLD's. The 0.04 was for benchrest where you start with a jammed bullet and the 0.04 and then up. 0.04 increments were the recommended test protocol. Google Berger VLD reloading also search this site for 7mm reloading and there are 2 threads in the reloading section (recent) that have a bunch of input on what other members have had work best in their rifles.

lancetkenyon Report post Posted December 6, 2015 I always start touching lands, .0400", .0800", .120" jumps. If it is a hunting rifle, make sure you can reliably feed from a magazine. My .300RUM has a huge jump to meet mag length, something like .180" jump, and shoots phenomenally. Share this post Link to post Share on other sites
MULEPACKHUNTER Report post Posted December 6, 2015 I had same issue on 700 308, .200 off for mag length but it shoots really well Share this post Link to post Share on other sites
AlexB Report post Posted December 6, 2015 .020 jump I find works well with begers then just do load work up. Might not fit in the mag Share this post Link to post Share on other sites
