Per the temptation of the PDW thread - I will make the 300BO move. I reload all my practice ammo - will use the 110 Barnes for serious work.
I have plenty of 300 BO brass that I collected over the years. I have plenty of 223 brass to convert with a Harbor Freight cutoff saw in route and a 3d printed jig on hand. Got some Lil Gun powder on hand from a previous project and primers. Lee dies for 300 BO just arrived. I will load on a Dillon 550.
Question is projectiles. I am thinking about using the .308 110 FMJs bulk projectiles for practice - these are originally intended for 30 Carbine. I will look for some heavier bullets for subs through my 30 caliber AAC suppressor.
Open for lessons on loading 300BO. Watching PSA for a deal on a 300BO pistol upper and I need a brace that fits on a carbine tube.
