  • Belt Mountain Punch Bullets??????

    Does anyone have experience with these bullets?

    And more specificly the Grizzly Cartridge offerings of these in 454C and 45-70?

    Thanks ...

    Gonna buy some

    No experience yet but I've been talking to them now for a bit. They are now making the .50 caliber bullets and I plan to load some up for my Beowulf. They sure seem good.

      They are very good. This is a 420gr 500 S&W. They are also very expensive. Which is why I don't load many of them.

      To say that they hold together well, is an understatement.

        Another Option

        I do not know why you are interested in FMJ bullets but there is an interesting bullet out of South Africa that you may be interested in at least looking at. It also is quite expensive but functions quite differently.


        1-308 145gr / 2-308 180gr / 3-338 250gr / 4-9.3 270gr / 5-375 270gr / 6-458 450gr / 7-470 500gr / 8-510 500gr / 9-505 540gr / 10-505 570gr

        The left two 458 bullets were fired into a steel drum filled with wet sand. Speeds were 2700 fps and 2300 fps from a 460 Weatherby rifle and the middle bullet picked up a layer of steel on the nose from the lid of the drum. The right hand bullet is the final production version of the bullet with the driving bands optimised for minimum pressure / maximum speed.

        The GS Custom FN design - The faster you drive them, the better they get. The left and middle bullets were fired from a 375 H&H rifle at 3000 and 2700 fps into wet sand. Note the progressive compression from front to rear compared to the unfired bullet at right.

        GS Custom FN bullets are precision lathe turned from solid copper with just the right hardness to allow the large flat meplat to progressively collapse the front of the bullet when it strikes and penetrates. The faster the bullet is driven, the more it expands in diameter when it strikes. This results in a projectile that relentlessly cuts through tissue, remaining heavy side forwards, with massive damage in the wound channel, no tumbling and with the least possibility of deflection. The examples in the two pictures were fired under controlled conditions into wet sand but closely represent bullets recovered from very, very large animals. Thus far we know of very few bullets recovered from game.

        All FN bullets employ our HV technology on the shank. This means that the bullet is bore diameter in the shank area with the thin series of bands at barrel groove diameter. The only stress imposed on the rifling by these bullets, is to cut the band and push it into the space behind it. The photos show clearly how this happens. This also gives superior gas sealing. All our bullets are moly-coated for further protection of the bore. When GS Custom FN bullets are loaded to normal speeds, recoil is reduced. When loaded to normal pressure levels, higher speeds than normal can be achieved. GS Custom FN bullets can in no way damage the barrels of a double rifle. The advantages are obvious.

          I was ecstatic to see that you were talking about the Punch bullets. I just read about them myself, and came to the forum to talk about them myself!
          I'm shopping for my first big handgun for bear protection. I was debating whether or not I should consider 44 mag... the only reason I'd consider it is because of Garrett's 330 gr. Hammerhead. They say that that's the one load that makes the 44 a viable option for coastal brownies. However, as impressed as I am by it, I fianlly decided to go bigger. Then I saw this article:

          After reading this, I'm reconsidering the 44! If the 300 gr. Punch bullet really outperforms the 330 gr. Hammerhead like that... then I'd say the gap between 44 Mag and 454 Casull is considerably closed!
          Other write-ups about Punch bullets (though not specifically the 44 Punch) can be found here:

          So, what do you all think? 300 gr. Punch @ 1400 out of a Redhawk or BFR? One question I still have, which I can't find the answer to, is the meplat diameter...anybody happen to know?

            Belt Mountain Heavy Jacket Penetrator Bullets
            Belt Mountain has introduced a new bullet designed for maximum penetration on Large and Dangerous Game. These lead-core brass solids are currently being produced in 300 gr. .45 caliber and 450 gr. .50 caliber. (nominal weights - the .510" diameter .50 caliber weighs closer to 460 gr.) They have the LBT-style nose, a very deep crimp groove, and knurling where there grease grooves would be on a lead bullet.

            45 caliber

            50 caliber

            A Test
            by Al Anderson with Lloyd Smale
            Here are a few of the Targets shot with the Belt Mountain Heavy Jacket Penetrator bullets. Also listed are some of the loads used and velocity.
            We did not do any penetration tests as we know how well they do and had only a limited number of bullets on hand. We will do some penetration tests when we get some more bullets.
            As you can see the harder they are pushed the accuracy dropped off. All groups were fired at 50 yards with peep sight on .50 Alaskan and open sights on the .454 Puma 92 Levergun. By the way it really liked that bullet! I need some more of them!
            All groups were 3 shots. Groups 1-7 were with .50 Alaskan and group 8 was with .454. I had to have a friend - Lloyd Smale - shoot the first 6 groups and I shot the last two. That is rare for me as I usually shoot everyone's firearms and usually have a few at the house to shoot and do triggers on.
            1. Old 455 grain solid with no lube. 55 grains IMR 3031 Velocity was 1447 * ES 25 SD * 12 Group was 1 3/8"
            2. Old 455 grain solid with no lube. 58 grains IMR 3031 didn't get velocity * Group was 2 1/2" and powder was to base of bullet with this load.
            3. Old 455 grain solid with no lube. 54 grains A RL7
              Velocity was 1736 * ES 15 * SD 8 * Group was 1 3/8"
            4. Old 455 grain solid with no lube. 57 grains A RL 7 Velocity was 1840 * Group size was 2 9/16"
            5. Old 455 grain solid with no lube. 58 grains IMR 4198 Velocity was 1950 * Group was 3 3/16"
            6. New 458 grain with hole in nose and lubed. 55 grains IMR 3031 Velocity was 1501 * ES 22 * SD 11 and group was 1 3/8"
            7. New 458 grain with hole in nose and lubed. 54 grains A RL 7 Velocity was 1730 and group was 1 3/8"
            8. 300 grain Solid with lube. 26 grains W 296 Velocity was 1700 Starline .454 Brass and Winchester Small Rifle primer. Group was 15/16".

            Notes by Jim Taylor
            I fired some of the first ones through the 454 Casull. I found that by lubing the knurling, velocity was increased and primer flattening was decreased. All I did to lube them was to wipe some of Paco's Apache Blue in the knurling as I was seating them.
            The load used was 30 gr. of WC820 ( military surplus H110).
            Velocity was 1616 fps.
            Fired into wet newsprint the 300 gr. slug penetrated 48 1/2". To give you some comparison, a factory .458 Winchester Magnum 510 gr. JSP fired into the same newsprint penetrated 24".
            The 450 gr. 50 caliber slug fired from a .500 Linebaugh at 1311 fps penetrated 49" in the same wet newsprint.
            When fired from the .50 Alaskan at 2000 fps the Belt Mountain bullet penetrated a whopping 66 inches!!
            There was no deformation to any of the bullets other than the engraved rifling marks.
