223 Remington | Hornady 62gr FMJ | H335 Revisited
TinMan
In this video I revisited some load development using H335 and a 62gr Hornady FMJ bullet. The load data I had originally used to determine my charge weights gave me very low velocities. I discovered that the data I had gathered was from sources that had used 24 and 26 inch barrels to test their loads. D’oh! Lyman’s 50th Edition manual gave me higher charge weight numbers that were gathered from a test barrel that was very similar to the one which I’m using, which is a 16″ 1:7 twist AR15 barrel from Palmetto State Armory. While these groups weren’t exactly what I was looking for (1 MOA-1.5 MOA) I did get much better velocities and some smaller groups than I did during the first test loads. Stick around for more load development posts using these budget projectiles and thanks for watching!
