Rookie Question II
« on: March 15, 2010, 11:02:32 am »
Ok, can you use CCI 310 large pistol magnum primers in 45acp?

Also, on the reloading tables I've compiled I notices that for hornady 185gr and 230gr XTPs there is no loading for HP-38 powder.  The recommended powers are all around it on the burn rate charts, some slower and some faster.  My brother in law got a pound of it, and finances prevent running out and buying another pound of powder right now.  We did load up 10 of each saturday, the 185gr were unsat, not working the action enough to eject, the 230s worked, but seemed light.  I'm in the process of acquiring a powder scale, but we were stuck with the Lee dipper on saturday that comes in the .45 dies. (.5cc I think)  Anybody, anybody?

    Handloads.org lists loads for HP-38 in both those bullet weights.  Reduce 10% from starting and work up with your XTP's.

    The Magnum primers are overkill in 45 ACP.  I would try to trade instead of using them.  However, in theory you could reduce your loads another 10% as a starting point, and work up.  I have no experience with doing this, so you are on your own, and a trade would be advised if you can find someone interested.

    Magnum primers will work if you reduce starting loads as already noted.  But they may not perform well.  You'll usually find large velocity spreads and sometimes dismal accuracy as a result of their use.  But if it's what you have, and you're just loading range ammo, go for it.  Don't use them for any serious ammo however.

    Chronographing is highly reccomended in this case as well.  In fact, it's near mandatory.
    This may be considered as the true palladium of liberty. . . . The right of self defence is the first law of nature: in most governments it has been the study of rulers to confine this right within the narrowest limits possible. Wherever standing armies are kept up, and the right of the people to keep and bear arms is, under any colour or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction- St. George Tucker, Blackstone's Commentaries

    You can use Winchester 231 data for HP38 they are the exact same powder.

    Get rid of your magnum primers.  If you want to use HP38 you'll need a scale.  The dipper isn't accurate enough for this combination. 

    185 grain XTP @ 1.235 OAL Start 5.5 grains, work up to 6.1  grains MAX
    230 grain XTP @ 1.235 OAL Start 5.0 grains, work up to 5.7 grains MAX

        I use the LEE dippers to and i found that they are off for the load data in the book. So i tested it out today on my friends digital scale.

         9mm 115grn FMJ the book says .5 cc of unique = 5.1grns.  Well that isn't true I measured it 10 times. The difference was a mean avg of .5 grains below the minimum starting load, .5cc equaled 4.6 grns. So i measured the .7 cc it came in at 5.3 grains which is exactly midway between the 5.1 to max 5.5 grains data. which explains why it fired great in my 92FS but didn't do well in the SIg P229, it has a heavier recoil spring. Next i will test the .45acp and .38/.357 load data for the 800x i use. But it won't matter for long. Since next month i'm getting a a LEE progressive and it will have the autodisk powder measure.

    scale vs dippers
    « Reply #5 on: March 18, 2010, 07:49:33 am »
    In my opinion you must get a scale.  If you can't get a digital (I would get a $100 not a $35 one like i did at first, the $100 RCBS scale has actually worked unlike the cheap one) then get at least an inexpensive Lee balance scale.

    The Lee dippers are ok once you calibrate them with a scale.  The chart that comes with the dippers was probably drawn up in consultation with a trial lawyer, as you've seen you really get less than what the chart says.
