9mm Load Data

[Galil5.56]

I drug out my Midway Load Map, which has what is usually pretty stout data compared to other data (at least the one for .45 ACP is), but in this case it is more conservative than other data. (4.3 Max)

Looks like someone put some "Clays" into their WW231... Something is just FLAT wrong here considering the propellant, and its pressure curve!

QuickLOAD shows the length of Hornady 115gr HP/XTP bullet at .545", while the Speer 115gr GDHP is listed as .544".

I can't confirm these measurements independently, as I don't load either bullet.

I also found your quote from the Speer #12 about seating depth in the 9mm Luger to be enlightening. Thanks!

Does, doesn't it.

Hmmm.....XTP is .001 longer. Statistically indifferent. That puts it .101 deeper than the GD at 1.125 which is where Hodgdon tested the GD at. (Using the OP's O.A.L. for the XTP of 1.025)

That doesn't make it better for sure. Hard for us to outguess it. A chrono would help out. My guess is it is over pressure. It would be interesting to see some velocities.

I measured several and am getting .540-.541 on the Hornady XTP.

I also weighed a couple and got 115 and 114.9 so they are pretty close in weight.

I do not have a chronograph but am not opposed to getting one. What does QuickLoad say for speed out of a 6.5 barrel ( Blackhawk single action) ?

Thanks
