87gr VMAX Bolt loads

[grayfox]

One feedback I'd offer is that, for this cartridge and others with relatively smaller case volumes, doing a ladder at 0.5 gr delta's will most likely miss or obscure your nodes. Nodes generally tend to show at about 3% intervals, (sometimes also at a 1.5%), so what I recommend is a delta of slightly less than 1% volume... for the 6 Arc, this means 0.3 gr until you want to narrow it down to a 0.2 gr. But 0.3 to start with. 0.5 makes some sense for a ladder in 308-family cartridges since they are about 50 grs +/- case volume. But for the grendel and the 6 Arc, 0.3 is a better choice. A 0.1 gr interval doesn't help much, it tends to use up too many bullets, and the MV delta for a 0.1 gr powder change is small enough to be lost in your MV SD interval/uncertainties -- down in the weeds so to speak.
This way, for the 6Arc, if you do a load range of at least 1.5-2.0 grains total front to back, you are most likely to have at least 1 node show up for you.
