Finishing up a .300 build (PSA lower, generic LPK, SBA3 brace, 9" BA barrel, ALG EMR V2 keymod, dead air break)
tried searching and couldn’t find anything on a recommended zero distance…I am specifically looking for zero recommendations on subsonic ammo only as this will likely be 100% suppressed and the suppressed subsonic is my real interest in the .300 blackout.
Anyway…any recommended zero/data available would be appreciated.
I have a Trijicon MRO RDS on my BCM 9” upper and it is zeroed at 50 yards for subsonic ammo. My intentions are the same as yours with an occasional foray into supersonic ammoland.
MPBR can be a nice way to tighten up your trajectory with subs. For 220’s with 7.62x39 a 20 yard zero works great for a 4" target which is head/neck shots on hogs. So from 20-102 yards my bullet is never more than 2" above or below the POA. There are certain areas I hunt where I have to use subs/can it’s a great way to work in the dark with range estimates or plinking at reasonable distances.
