Hey Trashy

Thanks for the offer but no I don’t have an OAL gauge and if my throat is in the short side I will just forego using 105s for the moment till my McGowen barrel is ready.

I shot the Proof again today , didn’t bother writing down velocity it was pretty much the same as the other day.

Both groups were under 1”
