Re: Body die issues.
Annealing is an unexact science, especially when you really have no way of ascertaining just how 'annealed' the necks really are other than templaq which is a good temperature indicator or the old standby method of crushing a case neck with a pair of Vicegrips (needle nose preferred) and noting the springback between a workhardened case and an annealed one....
Of course different brass manufacturers use different alloy blends and that throws in another curve ball. Me. I use the 'Broz' method of semi automatic annealing with a Bench Source Rotary Annealer.
I believe the necks are too soft but only time and another reload will tell.
Good luck, hope they shoot fine for you.
