That's why I suggested a step halfway between what you had.
The node should be bigger than 0.2 gr.
Remember 0.2/46 = 0.4% of case capacity.
If you wanted to see, sure you could do it.
But that's 30 more loaded rounds than a ladder at 44.8 and 45.2
The inside of lands measurement should be from base of case to ogive on bullet where it hits lands.
The magazine dimension is overall length, which is diffrent.
I get these dimensions from a hornady bullet comparator, a hornady oal guage and a modified case, and a caliper.
If you don't have one I'll lend you mine.
Pm me if you need it.
Magazine fed rifles will be limited to the length of the mag, metal mags generally are thinner construction than plastic and give a little more length.
