How much under max mag length?
I am working up loads for my new rifle. a Mossberg Patriot in 308.
After doing some measuring I believe the max mag length it about 2.860, as best I can measure....
Measuring the bullet to the lands, and backing off 0.020 leaved me at 2.865
I am going 0.020 off the lands to start, when I can. Its how I have done it forever. If we can please no arguments about where to start seating depth.
In any case the bullets a OTM and I am worried they could bind at the front due to the bullet style. How much should I measure back from my max estimated mag length?
My best guess at this point is 0.015 shorter than the mag? How much wiggle room do I need?
For reference 168g Hornady OTM
Hornady recommended COL of 2.800, which is a jump of 0.085 from the lands. I Want a little room to move back from there to adjust seating....
