Was playing around tonight on my reloading bench.
I have two bolt action rifles in the same caliber, one for hunting and one is for precision.
I use Hornady brass for the hunting one and LAPUA for the precision.
Tonight I was experimenting with my FLS die and measuring the neck tension it gave you. The results were interesting. An obvious statement would be that neck wall thickness affects neck tension. The point being I saw 2 very different neck tension measurements from 2 different brass manufacturers.
Now I also own a Neck Sizing Die where I can control the neck tension with the bushings but for some one with only a FLS Die, the different neck tensions could make a huge difference on accuracy.
Last point! For the hunting rifle I only full length size, for you hunting purists!
