I am reloading 223 in once fired 556 LC brass. I trimmed to 1.750, chamfered, deburred, swaged so brass is ready to go. It is an 18 inch (1/7 twist), 223 wylde chamber. I did not get consistent groups shooting this gun with 55 FMJ Federal AE factory ammo.
I am using the Hornady 62 grain FMJ bullet - https://www.hornady.com/assets/site/hornady/files/load-data/223-rem-60-62gr-1.pdf
The COAL tested was 2.229. What's the right strategy for getting the right OAL for these? I know for 9mm, its the plunk test. For bolt action, I used the sharpie method. Since these have a crimp line, do I just seat it until I get there and then add crimp? I know it has to be at least 2.229, but for function in a semi-auto, are there any special considerations?
Ladder - I am using H335, starting to max is 20.1 - 22.9. Any suggestions on what intervals to test and how many to make in each one? For my bolt action guns, I only make 5. But, for semiauto, should i increase that to 10 to make sure they cycle?
