I'm going with 46 gr. RL-7. Group seemed slightly tighter than the 52 TAC load. Either one would work.
And the bottom of the 178 Hammer bullet is just slightly into the 46 gr. powder column, which is at the top of the shoulder, slightly into the neck. No air space, minimal if any compression.
This Lee seater is hit or miss. Some rounds are about perfect, other have some run out. I know this isn't a long range target set up, I just like my rounds concentric. So after the Lee Factory crimp, I check them with a Sinclair gauge, correct runout with a TruAngle tool. I can often get what I'm looking for with one adjustment, sometimes it takes two or three. I probably need a better seater. I got the Lee die set because I wanted their Factory Crimp Die and getting it with a set is the cheapest way to go.
