OBT to MV Speadsheet
#14
All of my most accurate loads with Varget are 20 -50 fps above node 8, but well below 7. With LVR I have one good load in the node 7 range with the 105 Berger, but I can't get there with the 107 SMK or the 109 Berger without going well over 52,000 psi. I don't see much point in using LVR in the node 8 range as the results are not as good as Varget, probably due to being well below 100% case fill. The issue I see with both Varget and LVR is that they don't really shine until you get near 100% case capacity, or a little over. After messing with the spread sheet a good bit I don't see much advantage to it relative to my usual course of action, (as close to 100% case capacity as possible and .01 to .02 off the lands using the projectile of choice for the intended application). With this rifle the OBT theory likely would have led me astray. The good news is that It looks like I have a load using Varget under the 107 SMKs at 2.260 COAL: 2531fps, +/- 50,000 psi, that seems capable of 1/4 MOA. I have a couple other choices that show good promise, but QL predicts both of those are a bit above 52,000 psi, so I'm going with the lower pressure load for now.
