    I was looking through my reloading "stuff" and found three 100 rd boxes of Speer 165 gr Gold Dot hp that I have no idea when/where I bought them or how long they have been sitting there...I've got some new brass & 800X powder and I was thinking of reloading them for my G 29 with a Federal Arms barrel. I have a "recipe" of 165 gr GDHP and 11.0 gr of 800X and was wondering if this would work or should I try something else...any info or comments appreciated.:patriot:

    Don't see a recipe with that much right off, Hodgdon list the 155 with 9.8 grains at 1350 fps as a maximum but pressures are still on the low end. Please recheck you data to be sure!

    Working up carefully you might get to that charge weight... advise careful hand weighing with this powder.

    Best regards!

  4. I happend to find 3 boxes of 165 gr Speer GDHP at the local store on Saturday. It was a nice little surprise. I also scored some AA#9 and Power Pistol, so I'm gunna have me some fun. Speer lists the max for these as 10gr of Power Pistol, CCI 300 primers, and OAL of 1.255.

    15.2 grains of A9 with a mag primer is a nice load. It runs about 1330 from my g20. Nicely precise with not too much recoil. Very clean burn. The cases hardly look like they had any powder residue at all. I have run them faster, but this seemed to be a good overall velocity for handling and precision.

    Speer's max is 15.5 grains and they call for a CCI350. At that charge level there are absolutely no indications of excess pressure, and max case expansion was less than what I consider to be max in my barrel. Case capacity might be the limiting factor for upper limits of velocity for A9.
