Buffalo Bore .45 ACP +P

buffalo bore

Buffalo Bore is now shipping a zippy .45 ACP load that uses a Barnes 160 grain TAC-XP bullet.  Velocities in real world guns range from 1111 fps from a 2.5″ barrel Smith & Wesson 325PD revolver to 1260 fps from a 5″ Colt Gold Cup Series 90 pistol.

The Barnes TAC-XP bullets are all copper designs that claim to be very good at retaining weight and accuracy even through barriers like windshield glass.  Buffalo Bore estimates penetration of 15″ to 18″ in flesh and bone.

MSRP is $38.50 for a box of 20 rounds.

    160 grains at 1250 FPS? Pardon me for being a buzzkill, but the original 10mm Auto load by Norma was, in the 1980s, 200 grains at 1200 FPS, and was already rated for barriers like auto doors and windshield glass (the latter is something even the milspec M855 loading for 5.56mm NATO has some trouble with).

    • Leoon

      a big conical nosed FMJ coming out of pistol and plowing through a door cannot be compared to 5.56mm coming out of a barrel with a milspec rate of twist as if the 5.56mm dosent vear off imdiatly after contacting somthing like a car door then its not doing what it was designed to do and will probobly not live up to its exspected effectiveness on a soft target. the very definiton of apples and oranges basically

    • AlanHan

      The recoil of any real 10mm load is much greater than the 160’s and 165’s in .45ACP. I like the 10mm for field carry with flat nosed hard-cast lead. The G 20 4th and 21 SF have exactly the same grip dimensions. Still, I think the 10mm is better for animal protection in open spaces, at least for me. In a load like .45ACP Speer GD 200+P the muzzle blast and recoil are much more pleasant. Thing ‘indoors.’

      • Mazryonh

        It depends on the kind of space you’re shooting in. Didn’t Vietnam-War-era tunnel rats complain a lot about having to fire their M1911s in the VC/NVA tunnels?

        And if quietness is that much of a concern, you could always get a suppressor for a G20 (in heavier weights it can become subsonic as well). Check this video out for some ideas:


        Failing that, you could just get a Mechtech CCU for your Glock 20 and let the 16-inch barrel soak up the sound and most of the muzzle flash.

    250 rounds of this stuff would cover the cost of a glock 20.

    If your really interested in that kind of ballistics, the 10mm would at least give you room to play with.

  • cmblake6

    That is about some expensive ammo! I use Pow’r’ball in my 1911s. Not quite as expensive, excellent ballistics. Mind you, I’d happily use Buffalo Bore.

  • Christian Hedegaard-Schou

    So, it turns your .45acp into a .40S&W? Well I guess it’s cheaper than a barrel swap….

    • doc usn

      Prudy tho, isn’t it?

  • Leoon

    I can see the utility for a pistol caliber carbine if you want excellent ballistics but still want easily available ammo and ammo commonality with your pistol. however for concealed carry I would like to retain the possibility of a follow up shot and I don’t see that working out with something like this you will also have difficulty training up to deal with that much recoil from that gun due to the price of ammo, unless of course you can load it yourself in which case this loses all its utility because you can just purchase the components and probably come out on top from a cost per round standpoint.

    • Leoon

      well maybe if you wanted to hangun hunt with your carry gun as a method of developing confidence or just for the fun of it

    • AlanHan

      This ammo doesn’t produce an unusual amount of recoil. Because it’s a copper bullet, it is light-for-size. It’s just a trade off of weight for velocity. I’ve been shooting 165 and 160 grain higher-velocity for a few years from 1911’s, a G21, G36, and G30SF. Recoil isn’t a problem. Neither is reliability. Due to the lower-pressure nature of .45’s, these are much more pleasant than shooting .40 or 10mm, though I like 10mm for field use.

      • Leoon

        hmm didnt think of that probobly should have checked the actual loading data before commenting on utility. sorry about that.

        anyway what is the utility of such ammo in your opinion?

        • AlanHan

          I thought “well, in the G21 13 rounds of this will be lighter, adequate penetration, same sized hole, why not try it?” I found the recoil slightly less than what I usually carry, which is Gold Dot 200 gr +P. I may start to carry some version of 160-165 gr copper. More testing to do. In the G30SF I want to minimize weight subject to good performance. I started with the 165 grain cor-bon “flying ashtrays.” Laugh. Recently started with the copper, which is a better shape of bullet, actually. Time to run it for awhile through the 1911’s in the new loading.

          • Leoon

            sound’s great I will look into that

  • 2wheels

    Whoo, and I thought 185 was light for a .45!

    I don’t like light for caliber bullets, the lightest I’d go in a .45 is 200. Though 230 will always be my favorite.

    I find it hard to justify $2 a pop for SD ammo, especially when you have to shoot 50-100 rounds just to decide if it’s reliable. I understand light bullets–185s are a real pleasure to shoot (not that I can ever find any), and copper can be an excellent round for expansion. For me, these will remain one of those “If I were a rich man….” rounds. I’ll stick with PDX-1s at about have the cost (and that feed as smoothly as FMJ in my Kimber).

    I have a hard time justifying $3.80 for a gallon of gas or milk too.
