Loading 130 grain SOST MK319 for 300 Blackout. Any suggestions for overall cartridge length. I am using H110 with Winchester small rifle primers. I have not range tested as of yet. Just loading dummies at different lengths and measuring to my
magazine. The length which measures the best is O.A.L. of 2.155 inches. Measuring some commercial loads they have been as short as 2.145 inches.
New barrier blind ammo.

Re: New barrier blind ammo.
It's not new and they have been around since about 2014. Fired from a 300 Blackout at relatively low velocities I don't see anything that makes it a better barrier blind bullet than the Barnes Black Tip 110 and 120 grain bullets, that can be launched at even higher velocities from a 300 BO.
In my opinion these bullets are even harder to find than the Barnes Black Tips which currently are unobtanium in the current market.
If you have em' then enjoy em'.....I would start loading them as long as your magazine and chamber allow. Then you only can go shorter if accuracy and pressure are not to your liking.
IMHO and YMMV
