Ok, I'll ask you guys who probably been through it already. I'm working up a load for 6.8 spc stag that has a TA31H Acog on her. Center dot is 2 moa which is tough at 100 yards with my old eyes. I'm considering taking the acog off, put a leupold with fine crosshairs on the 6.8 just to develop the load. Is it possible to be precise enough with red dot to work up a load? Anybody been there, done that? What's the secret?
