Bjm42,
Figure you need to be closer to 0.030" off the lands for normal pressure. As you get closer, pressure starts to increases until you make contact with the lands, at which point pressure is increased by about 20%. So, in your load workup, you want to allow for that. I'm don't know how you arrived at 0.016" jump if you haven't loaded this bullet in this gun before. Every gun and bullet combination seems to have a preferred number.
An illustration: In the 1995 Precision Shooting Reloading Guide, one of the authors describes load for a 220 Swift in a 40X gun set up for benchrest match shooting. He seated all bullets 0.020" off the lands, as the general belief among BR competitors at the time held that this was best. He could not get the gun to average better than five-shot groups of half an inch at 100 yards. Not good enough for BR competition. Then one day when switching bullets to one that was longer, he accidentally turned the adjustment on his seating die the wrong way and loaded 20 rounds before he noticed they were seated 0.050" off the lands instead of 0.020". He considered pulling and reseating the bullets but decided just to shoot them for practice. To his amazement, the four 5-shot groups from these long-jump loads gave him two 1/4" groups and two true bugholes in the ones (between 0.1" and 0.19" CTC).
The bottom line is, don't believe in anybody's jump prescription for your gun and loads. You will have to find what your gun likes best for yourself. Read
this article for a method. It is geared to VLD shapes. Your V-max has a shorter ogive and will probably want shorter increments. I would try increments of 0.020" with that bullet design to see what you come up with.
Note that the COL's in the manuals are what they used with the test barrel they had, arriving at the powder charges shown.
