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.
Thanks for the offer. I already bought all that, using your links in another thread. That's why I mention, I was going to remeasure everything, because I think I measure the bullet length incorrectly. I will go .2g at a time. This is fun and entertaining. I was surprised the primers were all good and no signs of pressure on the brass either. So I will stay on the safe side. The longest I can shoot is 300y, so no need to try to push the envelope. My goal is to find a load that is good from 100y to maybe 600 y and stay on the safe zone. I also have 2 more bullets to test also. I have sierra HPBT match bullets and Hornandy Amax black (plastic tip). Since my distance is so close, I'll stay with 168 grs. We were talking yesterday about going to Malabars 600 yards range. If we do, Ill buy some 175 grs.
