What did you do in the reloading room today?

[43.6N]

How far off lands is the 2.5” OAL with the 107?

My chamber was reamed with a Manson reamer that called out a throat depth of 0.1646” and freebore of 0.1188”.
I made a dummy of my chamber, measuring 2.670” jammed with a 107tmk.
So, 2.500 would be 0.170” short of lands.
Sounds like a ton. Most all the load data I could find, put almost every bullet around the 2.5 mark.

Here is where I see the 107 bearing surface/boat-tail transition lining up at different seating depths.

Loaded the last of my speer 75gr gold dots up for my 223, need to test them on fur and see if im gonna run bergers, tmk's, or gold dots. So far berger wins the accuracy, but not by much. Not 100% happy with bergers in coyotes.
