tOBR Performance with SWFA 1-6X and 77G SWA

[RonboF117]

Just logged in a SWFA 1-6X short dot to our inventory and took it to the range to zero it at 100 yards. Using our LaRue 16" tOBR and Southwest Ammo's 77G .223 ammo; the combination worked well showing .474 MOA max spread (CTC). Established a rough vertical zero with 62G PMC X-TAC and then switched to SWA 77G. The picture shown is the first and only five rounds of 77G. It was pretty windy so I decided to wait for a more calm day for the windage. MOA figure calculated using On Target software v3.81.

So to answer the question many folks have asked concerning the performance of the weapon and optic, I think the picture gives you a good idea. The weapon/ammo combination is very good. The optic allowed me to easily see hits in both the white and black at 100 yards at 6X and accurately repeat placement of crosshairs across numerous shots. If someone needs the environmental and ballistic data, PM me.

Shit I can't see 308 holes at 100 yards with a 10x. You must have some good eyes to see .223 holes with 6x.

Just one question, the larue tactical ruler is marked in .020 & .100 ths, not 50ths & 10ths

Tipper, to answer your question, I used the ruler shown to establish for the software what one inch was. The program then calculated everything else knowing what ammo was used (for diameter) and where the rounds hit.

Thats what I was thinking. 223 holes in the black with a 6x is a pretty tough feet to accomplish.

The black was in the black target area I provided in the photo.
