Check out the South Florida Precision Rifle Association page on Facebook. There are guys there that have memberships to JTAC and may be able to take guests with them. Also, check out the long range matches that GCP Rifle Co holds there.
Did you put in your barrel twist under the spin drift section?
Is your sight height really 1.5” or closer to 1.9”? Also, update the current and zero weather data.
That is who Defiance used for DLC in the past. From what I understand, the wait times got too long and they couldn’t afford to keep the customer waiting. Defiance now offers nitride only through H&M.
I shoot for Defiance btw.
