Never ever have air space with H110/296


The load data shows all H-110 starting loads as non-compressed.


As I said never ever have air space with H110/296





Said another way, published load data shows H-110 loads with air space.



You sure about that




Yes.

The Starline brass I used is 1.2 inches long and FL sized. With 12.2 grains of H110, the case is filled to .365 inches below the mouth. From the top of the cannelure of a 100 gr XTP to the base of the bullet is .315, and Hodgdon doesn't recommend seating it that deeply. That translates to air space. Maybe the Federal brass they used was thicker than my Starline. Maybe my Lyman caliper is off. Maybe the XTP bullets I have are from a different lot and are of different dimensions than those Hodgdon used. But make no mistake about it, there is air space at 12.2 grains. That's why I went with 12.5. Because that is where, based on my observations, the base of the bullet (Swift A-Frame) just makes very light contact.

So go ahead and reel off another childish goddam retort now. It's very important for you to think I am wrong/idiot. I don't want to steal your joy.
