First reloads today 300 blkout. Have question about COAL

[Biggie1976]

finished first 50 today and use new brass H110 19.4 g. Barnes 110 TAC. COAL was 2.25 just wondering who uses this setup and why your COAL is.
I did a bunch of research and COAL ranges from 2.05 to 2.25 for multiple manufacturers.

It’s whatever fits in the mag and is almost accurate in your gun. A more precise way to measure is using base to ogive (BTO). Buy a comparator. It’s especially helpful with open tip match (OTM) bullets.

Never had any issues loading supers to mag length.

Subs can get wonky though. Especially the coated cast varieties. Fat subs can sometimes drag on the rib inside of magazines like pmags, which is probably why they make 300BO specific mags.
