Seating depth doesn’t matter

[Tod Hendricks]

I would add that in additon to the obvious value of your observations and conclusions about the 180 Hybrid, I really appreciate the manner in which you took advantage of the electronic target system to carry out the testing. I recently started using my ShotMarker for carrying out ladder tests, and it greatly facilitated the process. Clearly, the two-shot process outlined here could easily be used to carry out seating depth testing at whatever maximum shooting distance might be available to someone; i.e. up to 1000 yd. But I can also envision that it could be adapted to other purposes, such as setting a tuner. Obviously, the need for having low and/or stable wind conditions becomes more important as the test distance increases, which is why many of us do a certain amount of testing at 100 yds. Nonetheless, I think the potential value of electronic targets in the load development process may be under-appreciated.

That’s a great point! My Shotmarkers are almost indispensable. I run two on the same target, accuracy consistency between them is very good.

Since you mentioned it I’ll post a tuner test. My tuner use and testing is pretty limited. The second pic is how I do powder ladders utilizing the Shotmarker. Every barrel has a tab in a 3 ring binder, every target gets printed and filed in a binder, the bad targets are just as important as the good ones.
