    What self defense 10 mm ammo does everyone recommend? Plus, because 10 mm is somewhat hard to find where can I get your recommended 10 mm ammo?

    Also, where can I get some cheaper 10 mm (not personal defense rounds) for range time?

    Bought a 10 mm at auction about 60 days ago and finally got a chance to shoot it yesterday. Really like the 10 mm. Store/range had only some Hornady 180 gr XTP and it was pretty pricey ($19.99 for 20). That's a little too pricey to shoot a lot of at the range.

    Buffalo Bore is good self defense ammo. It isnt cheap though. Also, if you are using the 10mm as your SD gun, you will want something hotter than cheap Blazer or Ultramax practice ammo. The difference in recoil is pretty big. Georgia Arms has decent ammo closer to full power loads at a good price.

    I never shot Buffalo Bore in the G20 I used to have but did fire Double Tap which ran close to advertised velocity. For some reason, the G20 I had would cycle Blazer but not the DT. Two trips to Glock and no improvement, sold the gun. Don

    It's pretty nice
    Reeds and Georgia-Arms make ammo that is much hotter than any .40 but not as hot as BB or DT (advertised). Makes carrying 10mm worthwhile while allowing for decent follow up shots. The G-A 155 GD @ 1375 and 180 GD @ 1150 are nice SD loads IMO. I've shot about 1,000 of each over the years through both Glocks and a 6.5" S&W 610 revolver. Never had any feeding, ignition or extraction issues with any G-A ammo in any caliber and I've shot a lot of it. Reeds has Silvertips and Golden Sabers loaded pretty hot and he waterproofs the primers. I've shot limited amount of 165 and 180 Golden Sabers made by Reeds, not an issue yet.
  5. Reload.. I carry 230gr. hard cast DT in the woods. In town I carry either my 380, 9mm or 40 cal

    For personal protection in my 10mm (G20) I use DoubleTap and have for years. My choices of bullets and weights are contingent on where I am relying on the pistol for personal defense i.e. home, woods or carry in general public.

    I have used the following DoubleTap without any problems of any kind in 10mm: 135gr nosler, 165 gr brass jacketed (which is Golden Sabers) 180 gr bonded defense (which is Gold Dots) 180 gr controlled expansion (Last I knew, were Hornady XTP) 200 gr controlled expansion ( Can't verify, but I think it is a Montana Gold).

    Although I have had great performance and accuracy with any DoubleTap in 10mm plus other calibers, I have the best accuracy in 10mm with the 165gr brass jacketed and 180 gr controlled expansion.

    IMO, for obvious reasons in warm weather, (people lightly clothed) for general carry where innocent bystanders are possible, I would suggest the 180 gr bonded defense as the maximum weight. Preferably go lighter in warm weather when bystanders are a risk.

    Controlled expansion and heavy loads are too much risk for over-penetration in some cases, especially considering most self defense situations occurs in less than 20 feet apart.

    Another good point with DoubleTap is that they used nickel plated brass. (Starline last I knew) It feeds very smooth.

    I have never tried Buffalo Bore, but hear it is top notch too.

    165 Gold Dot's from Double Tap seem to work great. I like the GD because it's a good bonded bullet that can hold up to the power and stay together.

    Win 175gr silvertips are not to shabby for a factory loading. that or some hornady XTP's should hold you over til you can order...

    buffalo bore, or double tap.... top notch, just make sure you get gold dots in the rounds, some I have seen are loaded with montana gold bullets, which are target bullets only, do not use for self defense, IDK why they even thought of loading those.

    if your really serious about that 10mm, get into reloading. you could be fully set up and running for under $200 (Lee press, scale, tumbler, dies, ect.), and make any ammo you want... for a hell of a lot less than $1 a round....:whistling:
  9. The biggest problem with full power 10mm loads is finding what .40S&W design bullets will perform at fast 10mm velocities.

    As an example, I've tested, and blown up 180gr Gold Dots at ~1300fps; another .40S&W design bullet.

    180gr/10mm ammo at 1150fps isn't that much difference than the Winchester .40S&W 180gr PDX which I chronographed at 1080fps.

    Factory Winchester 175gr Silvertips @1290fps is designed for 10mm velocities.

    For self defense scenarios and after doing a lot of 10mm testing, given high center chest hits, I'm not sure the 10mm has a significant advantage over other caliber, bullet specific, combinations. In addition, the G20 gives slower follow-up shot times.

    From a Mike McNett post, there's a lot of caliber overlap performance with DT ammo; i.e. 9mm/147gr Gold Dot vs 10mm/155gr Gold Dot.

    Head-to-head bullet sectional density, 10mm/180gr and .45auto/230gr Gold Dots yield same expansion/penetration numbers.

    Pushing the 165gr Gold Dot into the low 1300s (let alone 1400fps), all 165gr Gold Dots I tested peeled back like this;


    9mm/147gr XTPs @1200fps give the same penetration length as DT's 10mm/200gr XTPs, with considerably less recoil.

    good overall post bob,

    45 and 10mm are very close in gel and such, 10mm gold dots are indeed under-developed for full bore 10mm loads....40 S&W bullets no doubt.

    however, they still retain a good amount of weight, my mule deer tests confirm...:whistling:(180gr gold dot @ 1300~fps), full 90 deg. chest penetration.

    However, I wonder which caliber 45/10 dumped more energy in the same distance of gel...?:dunno:
    similar expanded bullet diameter, and penetration.... vastly different wound cavities...

    Xtp's make a better hunting/penetration round, but gold dots are perfect for the two legged fodder... gold dots in the 10, kinda remind me of the 357 mag 125gr rem scalloped jacket, but better....

    Spend about $300 bucks on a reasonably inexpensive reloading setup.. that is the only way you'll get anywhere w/ 10mm..

    As for self defense.. Georgia Arms, Double Tap, Buffalo Bore, etc... maybe Corbon. If you buy Federal, Speer, etc.. they all neuter it, and you might as well carry a 40...

    I'm curious.. did you not research this at all before you bought the 10mm, or was it an impulse buy, etc?

    Gold Dot won't, Golden Sabre won't, Hydrashock won't. The proven performers have been cast lead alloy (you don't need super hard bullets), the Hornady XTP (my personal favorite), and the Winchester Silvertip. Haven't tested the Barnes bullets but from field reports by the hunters, I'll pass on those and focus efforts elsewhere.

    It is my personal opinion the best bullet for self defense 10mm at 10mm velocity is the Hornady XTP. For a mid range (split the .40 and 10mm in half) 10mm defense load, the Gold Dot is the winner over other jacketed designs.

    You are so not getting a Christmas card this year from me. :rofl:

    Here is the nice thing about 10mm: Just about any load will get the job done.

    Of the current loads, I like the 175grWSTHP & 155grXTP. Both full power loads & available. I understand DT has been swapping out bullets, so you really have no idea what yo uare getting. BB makes good ammo, but spendy. GA for practice but reloading will save you tons in a 10mm.
  15. The mantle over the fireplace only has so much room, however, 1 Christmas card instead of zero would make me feel better. :supergrin:

    Bob :cowboy:
  16. I hear you. I get frustrated at times trying to find which bullets will consistantly perform, and at what velocities?

    I've loaded the 155gr XTP upper 1300s for carry while working outdoors, a very rural area; but there's also a snubbie .44 Special with hardcasts in the back pocket.

    I've also blown up 9mm bullets at upper .38Super velocities; however, the .38Super can be loaded with .357mag design bullets. With the recoil of a G17, on my hip is a Colt 1911 loaded with 125gr XTPs ~upper 1400s-1500fps. That bullet at that velocity reminds me also of the .357mag/125gr SJHP.

    As for hunting deer, what do you think of Buffalo Bore's new .45auto/255gr hardcast ammo, other than being very expensive?

    glock-20. 200 grain xtp from d.t. - it'll drop whitetail at 50 yards so, it should have no problem with a 300 pound methhead at 8 feet. now for the indoor range or kicking it at the walmart parking lot, rem. 180 grainers work well too.

    just curious, but where have you seen a 300 lb methhead? usually there at or under 100lbs... so your gonna need those light and fast loads...:rofl:

    Bob, seems like a stout 45 load. But imo, even a 45acp would be best served by a good hp for deers. 230 xtp?
    I am however going to work up some .357 sig loads with 125gr golddots' @1450-1500fps real soon.
  19. Haven't seen any 300lb tweekers around here either.

    Looking forward to reading your 125gr Gold Dot tests, I like the shallow cavity GDs. The Para feeds them fine, but the Colt doesn't, at any COAL. :crying: :supergrin:

    I load the 125gr GDs for the G17, upper 1200s-low 1300s; big performance difference vs the 124gr GD at that velocity.

    Bob :cowboy:
  20. I use the Win 175gr STHP myself, altough I see some DT 165gr GDHP in the future.
