    Default Any favorite 10mm Auto loads

    Looking for deep penetrating loads. Anyone have favorites for a Glock 20...?

    My Blue Dot loads (11.0 grains) with some 180 grain FMJs were 100 feet per second less than the books claimed they would be...

    Gonna try some 800X next week.

    Plus I gotta find a 20-22 pound recoil spring...

    I used to run AA #9 powder with 200gr Hornady and Montana Gold FMJ's. It provided good velocities and was the cleanest burning powder I'd ever used.

    I had two Glock 20's, and both of them hated Winchester primers. About 20% would not go off the first time. I switched to CCI and Federal's and the problem went away.

    Thanks Dan. I just bought some AA#9 up in Kenai last night. I did use Winchester primers and Starline brass.. They all went off fine, but there were considerable velocity variations. From 1150 up to 1250... Oddly enough it grouped well. Go Figure...

    I'm curious as well, I'll be loading for mine in the next month. I have some 180gr Berry's plated I want to load up for practice and Hornandy 180gr XTP's etc. I'm looking for a 180 to 200gr FP copper solids if anyone knows of any. I'm going to be using HS-6 and 800X. I have a G-20 with a Lone Wolff barrel and I'm using a 24# spring that works well for anything from American Eagle red box up to Double Tap 200gr WFNGC without a hiccup.

    The 180 grain Speer TMJ are a nice flat noised full metal jacket with a scalloped looking base. Plus they were not evry expensive. Three Bears and Sportmans Warehouse carry those. I will probably need to order some 200 grain FMJ bullets. I think a 200 grain at 1,200 would be a good penetrating round.

    Sorry about the typos...

    I'm getting into a bottle of port as we speak.
    It looks like we are looking for something similar perhaps? I'm trying to get a bullet with good penetration that will stand up to higher velocities and not break the bank. Kind of and all purpose defense load that I can also practice with and not cringe when I pull the trigger due to the cost. I kind of aim high and to the left when I do that!
    I'll look into those Speer TMJ's I don't know why I have overlooked those before.

    I like the Laser Cast 180s for just shootin' bullets. For hunting I really like the Hornady XTP, also in 180gr. I havent done a lot of experimenting with powder, mostly I've used Blue Dot and some AA#9. Every few years I try the Speer Gold Dot, but it just doesnt come put of my gun as straight as the Hornadys.

    800 X with Sierra 190gr FPJ makes a excellent bear round loaded full throtle.

    I just picked up another 10mm, so it looks like I'll be putting together some more ammo in the near future. Darn the bad luck!

    Just got back from the range... After having to pull the truck out of a snow bank..

    Today's recipe was:
    200 grain Hornady XTP (could not find any solids during my last trip to Kenai.)
    13.8 grains AA #9
    Starline brass
    Fired from a stock Glock 20 SF

    CCI-300 primer = 1,150 fps good group
    Win WLP primer= 1,165 fps and a double group
    CCI-350 mag primer = 1,190 fps and a group slightly larger than the 300s

    I still need to buy a 22 pound spring since it looks like it is opening up a little too soon with hotter loads.

    So you scored that thing did you? It sure sounded like a great deal! Congratulations!

    I am already looking at getting another barrel. The brass is swelling in this new G-20 from 0.422 to 0.435. The chamber is super loose.

    175 grain WW Silvertip= 1,195 fps (Ok group)
    180 gr Fed Hydra Shok= 955 fps wimpy FBI loads
    200gr CorBon penetrat= 1,065 fps Not as advertised

    Has anyone messed around with Power Pistol in the 180 to 200gr TMJ arena? I'm curious as it requires less volume than the others to load and may be better for the heavier bullets? I'm also reading a few reloaders info that using magnum primers seems to bring the consistancy together for most of the heavier loads. I'm still trying to put some rounds together, maybe over Thanksgiving week I'll sit don for a few.

    I wonder how much more velocity I would get with a 6 inch hunting barrel versus the 4.6 inch factory barrel?

    Yeah you will gain some, not a huge amount, I think I heard up to 50fps. On your 200gr loads, I would think you could load them a hotter, maybe Tenmm or BRWNBR would have more in put there.

    I have a 20 and or 22# flat wound, might have a stainless guide rod around also. Or can order whatever you want, like a BBL! Free shipping to my door. Products would be from Lone Wolf.

    Went out again today with a different chronograph. (I shot the other one last week)\

    This was pretty much just a verification and checking other primers.
    G-20SF with stock barrel and spring.

    200 grain Hornady XTP. All loaded to 1.250 col. Groups at 15 yards, temp 20F
    All with 14.0 grains AA#9 Star-Line brass
    CCI-300 = 1,162 fps (30fps ES) and a 2.0 inch group (within 7 fps from the other chronograph)
    WW-WLR= 1,151 fps (7 fps ES) and a 1.5 inch group
    CCI-350= 1,188 fps (18fps ES) and a 0.80 inch group

    All loads showed a lot of firing pin dragging across the primer since I am still using the wimpy stock recoil spring.

    Installed a 20 pound spring and a stainless guide:
    The drag marks on the primers are now gone. Plus the groups are better for some reason.

    Found some old 180 grain Hornady XTPs
    14.7 grains AA#9
    Virgin Star-Line brass
    CCI-350 primer
    1.257 col with a heavy taper crimp
    1,322 fps average and a pretty good group.
    Still a little too hot, so next time I will back it down some more.

    I think you would be better off going to a heavier bullet if you are looking for penetration. Like maybe a 220 or 230gr. They will penatrate better even at a lower speed. And you can use cheap cast and they still won't come apart. Speed is not the answer for penetration, bullet shape and more mass will serve you better.
