[QUOTE="aushunter1, post: 1863355, member: 57533"] Absolutely! I do all my LD for any of my cartridges with any projectile the same way. Start at 10thou off the lands, go through the charge range, pick the best group of 5 shots, change CBTO for that load to 5thou, 15thou & 20thou. Once I have found the best from those changes I will then again do a few incremental powder charge changes like -0.1gr, -0.2gr & +0.1gr, +0.2gr. This has never done me wrong & I have never had to seat any deeper than the 20thou without getting the result even with Berger VLD's, however if I still wasn't happy I would go further than 20thou. Imo though you should be working of CBTO not COAL, as all projectiles have different ogive shape you want to be working from a known distance to or from the lands, by measuring to the point how do you know how far you are away from the lands?? And as mentioned this changes for each projectile! [/QUOTE]
