    I reload a few thousand .40 a year and I've finally decided to do the same with 10mm. what should I look for in reloading the 10? I plan on getting another powder dispenser dedicated for the10, same with the dies. For the .40 I use power pistol and vv n320, guess that is good for the 10 as well. Any suggestions/tips/advice????

    Its pretty straight forward... One thing I found interesting... there are some cases floating around with SMALL primer pockets...

    Good luck, its a great caliber!

    The mechanics are the same, the only difference is that most people don't get an insatiable urge to hot-rod the forty cal....

    Buying brass stinks, I've started shooting forty brass loaded to ten mil OAL to save a few bucks, considered unsafe in most guns, but appears to be fine in a Glock...

    The Power Pistol should be great for a number of bullet weghts in 10. The N320 is pretty fast for just about any 10mm load, great for plinking rounds, but not for anything the 10mm is really about. When you use N320, just make them 40S&W, brass is cheaper.

    I have to warn you, the 10mm round is so addictive, it should carry a warning label.

    Excuse my minor hijack, but I'm interested if you know which brand of 10mm brass has SPP? Thanks in advance.

    what would a good starting load be with power pistol or unique? 180 grain precision delta?

    My Lee 2nd Edition lists the following for 180gr jacketed:

    PP 8.2 Start - 8.7 max at 1.250"
    Unique 6.5 Start - 7.0 max at 1.250"

    I have not loaded either in 10mm, but off the top of my head the Unique seems kind of light, the PP seems closer to the mark. You might want to double check a few more sources before loading a bunch using the above.

    I shoot IDPA with my G20.

    The load I have recently switched to is (and what I ran with Saturday was):

    180 Power Bond FP
    Starline Brass
    CCI 300
    13.5 grains Accurate no. 9
    1.25" COL

    About 1175 fps depending upon the temperature. This is by no means a gamer load since the power factor is north of 210. I like to run a little warmer to get practice time with the 20. I am at a disadvantage since minimum PF is 125. It would be pretty difficult to get to a PF that low in a G20. A 135 grainer at about 950 would be close. I have no idea if it would cycle the big 20 or not.

    Prior, I ran a few thousand of these loads with good groups:

    180 Berry's FP DS plated
    Mixed brass
    Whatever LP primer
    9.3 grains Blue Dot
    1.26" COL
    1035 fps

    Speed limits are severely limited with Berry's, but otherwise this particular load had respectable groups. I switched to Power Bond bullets because they are much better suited for 10mm speeds and they are the same price.

    do yourself a big favor and drop the cash on at least 500 pieces, it makes the 10mm game so much more enjoyable!

    I am not a fan of unique, but it is OK if you push it a bit, it tends to clean up at the higher power loadings.
    Alliant says 8grs max.
    Id start at 7 and work up.

    Most of the small pistol primer brass I have for 10mm has been Federal that were from the FBI/LEO firing range, they are loaded for indoor use with Ballistclean Primers to reduce airborne lead contaminates...for more info look at the Ballisticlean Ammo specs. :dunno:

    Yeah, i dont know if a light load would cycle the 20 either. So, acurate #9 huh? I wonder if precision delta bullets could handle the speed. I am also looking at zero bullets for both the .40 and 10mm. I am going to continue to use underwood ammo until ive got about 1k cases.

    "Light load", like .40 S&W loads? They cycle fine.
