That particular load is for my 16" M4 with a red dot so I can't speak to it's accuracy.
I do have a load using a 75 RMR with Tac for my WOA 26" upper that is very accurate with a SD around 5.5 for 10 shots. Effective out to 670 yards which is the limit of our range.
I found it takes some load development, maybe more so than other cartridges. I worked up a powder charge first then tried different OALs. Aero Precision 16" with 55 FMJBT and Tac.
I bought a moving target system from Action Targets years ago. It reverses and runs off a wearable battery pack, a 12 volt battery or the battery in a vehicle.
When I get home I'll see what the motor shows. It's not very big.
With the new update transfered a session to my S21 and was able to read it, etc. Cool.
I then downloaded it to the device. However, I can't find that spreadsheet anywhere on the S21. ???
Anyone know where these downloads go?
I have over 20 different years of LC 556 and they test between 125 to 127. For mixed LC 556 I use 126. Works fine.
I also have a very large batch of LC21 and everytime a primer pocket gets loose I analyze it. So far they are consistently testing at 125.
I watched something where Alex said 1...
I didn't know what to start with so focused on the powder charge first.
For my AR mag length loads I used 2.250" and worked up the charge with Ramshot Tac and found a sweet spot.
For single shot long range work I measured the lands and tried the same powder charge but changed the OAL. Best...
