MPA BA Academy Shoulder Bump using Redding Instant Indicator

[@volvosan]

I use the Hornady comparator to accomplish the same task for $35 and you can do it off-press. My fired brass is defining my chamber dimensions & I like to bump them down .0025 just like you. Plus it tells me how close my chamber is to SAAMI specs. I've got modern rifles that push the shoulder .001-.002 & military rifles that expand the brass .019.

Thanks Phil for another educational piece

Hard to imagine reloading precision without this tool. I use two presses to utilize it.

[@cncmts]

I only touched on 1 of the multiple uses of this gage. Its a wonderful tool.

[@zgennaro]

Indeed. I wonder what people are using instead of this for all their measurements? If you have two presses or a turret press I wonder what would be faster or more accurate?

[@jasonmpd2946]

I'd imagine a GO gauge for the appropriate cartridge can be a good starting point, particularly if you used the same GO gauge to set heads pace on your rifle.

🤙thanks Phil, now were can i get that gauge and the indicator cases..

[@vinago100]

Is it safe to go below the dimensions of the case gauge this unit comes with? I understands the gauge is the minimum head space aloud under sammi specs...? Keep in mind im new to reloading so i still have lots to learn. Thanks!

Did i miss the part where you wiped the case lube completely off the case before checking it in the indicator die/gauge?

open your eyes windbag

[@joeloehlephotography]

Probably stick up too much for a Forster Press?

[@zgennaro]

Yes. I use two presses for that reason.

[@remington334]

Seems like your fired brass was .001 over the length of your gage originally measured. Then by setting your die up to read . 003 shorter from the zero reading, it seems to me you are setting the shoulder back .004 from your fired case

[@spraynpray]

He rezeroed on his fired brass. So .003 bump.
