A friend came over and we loaded 40 300WSM cartridges to a COL we found on the Hogdon gunpowder website. When he got home and tried to load them, not a single one would load as they were all too long.
So I thought I would ask what all of you experts have found to be the right COL for the cartridge.
Specific info -
Powder - H4350 - 61gr
Bullet - Hornady 180gr BTSP
COL - 2.850
Interestingly enough, when we loaded 1 cartridge with a 180gr SST, it loaded. I am thinking the COL should be somewhere around 2.80.
What say all you reloading experts? Murphy?
Thank you much in advance.
