I appreciate the post. Looks like a lot of good, but very general. Info. The part I’m missing is the “if this is what’s happening, here’s what you tweak” section. For example, I’m using N320, 124gr Berry’s FP ammo, CCI primers. 2 Tanfo’s, brass ejecting forward of the line on an indoor range (which means no brass recovery). What variable do I tweak to change the angle of ejection? That’s the guide I’m looking for. Theoretically, there should be some consistency and repeatability in these firearms, right? Meaning, “if you pull on this lever, you can expect this type of result”, right? If not, how does anyone know where to start to achieve a given result? Sent from my iPad using Tapatalk
