Ill start out. Just got around to working up my first loads for 6mm arc. Had to buy some factory ammo to get brass, and have 250pcs of starline on backorder. Factory ammo shot just ok, not great.
Put my first loads together today, just a small batch to check for pressure signs, function in the gun, and a rough idea on velocity. Using the once fired Hornady brass and CCI Small rifle magnums due to being in an AR.
107g SMK CFE 223, 29.1g, 28.8g, 28.5g, 28.2g, 27.9g expected max velocity 2575fps
85g Nosler Partiton, CFE 223, 30.9g, 30.6g, 30.3g, 30.0g, 29.7g expected max velocity 2800fps
75g V-max Ramshot TAC 30.5g, 30.2g, 29.9g, 29.6g, 29.3g expected max velocity 3000fps
I am using Hornady's gas gun data, which tests with an 18 in barrel, however I have a 20in barrel. Really curious to see how the velocities pan out.
Really been slacking on my 223 reloading got a lot of brass processing to do. But working up this 6mm arc has been more fun.
What project are yall currently tinkering with?
