FULL POWER+ 30 M1 CARBINE

BUFFALO BORE FULL POWER+ U.S. 30 M1 CARBINE AMMUNITION
110-grain JHP @ 2,100 fps
20-Round Box

ITEM 46C

For years customers have asked me for a couple of full power 30 M1 Carbine loads. I’m calling these loads “Full Power+” instead of +P because they are not technically +P as they are all within the SAAMI max. average pressure of 40,000 CUP, but they are much more powerful than ordinary run-of-the-mill M1 Carbine ammo. 

ANY/ALL M1 chambered carbines that are in normal operating condition will safely fire these loads, as they are operating within SAAMI specs.

THE PROBLEM:

The typical current commercially manufactured 30 M1 Carbine ammo is running at or below 1,900 fps with 110gr. bullets, when fired in good old US military 30 M1 Carbines, with their 18-inch barrels. When the US issued this military cartridge in 1941, it was designed to propel a 110gr. bullet @ 1970 fps out of the carbine…..it is possible to exceed 2,100 fps with 110gr. bullets and still be within the SAAMI max. average pressure limits of 40,000 CUP.

We are not making this ammo to be cheap blaster/plinking ammo, although you can certainly do that if you like. This ammo is designed to be useful in defending ones’ life or in harvesting game up to the size of 200 lb. critters.

While three of these Buffalo Bore 30 M1 Carbine loads are giving close to 2,100 fps in my various 30 M1 Carbines, item 46D, which utilizes a heavier bullet is not, as can be seen below.

Item 46A—110gr Jacketed Soft Point @ 2100 fps

>  2,122 fps - Inland/General Motors
>  2,114 fps - Underwood
>  2,105 fps - Exel
>  2,107 fps - Spare parts carbine
>  1,587 fps - Ruger Blackhawk, 7.5

Item 46B—110gr. FMJ-RN @ 2100 fps

>  2,121 fps - Inland/General Motors
>  2,116 fps - Underwood
>  2,098 fps - Exel
>  2,100 fps - Spare parts carbine
>  1,638 fps - Ruger Blackhawk, 7.5

Item 46C—110gr. JHP @ 2100 fps

>  Inland/ General Motors
>  Underwood
>  Exel
>  Spare parts carbine
>  Ruger Blackhawk, 7.5

Item 46D—125gr. Hard Cast Gas Check @ 2100 fps

>  1,945 fps - Inland/General Motors
>  1,949 fps - Underwood
>  1,935 fps - Exel
>  1,929 fps - spare parts carbine
>  1,641 fps - Ruger Blackhawk, 7.5

I was surprised at the consistency of these military carbines, from gun to gun as can be seen in the above data.

Item 46A is designed to be a controlled expansion load and you should see around 18 inches of penetration in living mammalian tissue, depending on which bones are struck.

Item 46B utilizes an FMJ round nosed bullet much like the original military configuration and is designed to be a deep penetrating load. Expect 30+ inches of penetration in living mammalian tissues depending on which bones are struck.

Item 46C utilizes a radically expanding JHP bullet and you can expect around 12-13 inches of penetration in living mammalian tissues.

Item 46D utilizes a flat nosed 125gr. hard cast (21BHN) gas checked bullet. If I were to use any M1 carbine for defense against black bear, boar hunting or for general woods carry, this would be my load of choice as it will penetrate at least three feet (probably more) in living mammalian tissue, depending on which bones are struck. A few things should be noted about this load.

First, 46D is the only commercially produced high-performance heavy (125gr.) bulleted load for the M1 carbine.

Second, flat nosed bullets tend to crush their way through material, while round nose bullets tend to slip and slide which does not always allow them to stay perfectly nose forward, so round nose bullets can veer off path and normally do not penetrate as deeply as flat nosed bullets which stay 100% nose forward and have the added benefit of doing much more terminal damage than round nose bullets.

Third, only my Inland carbine cycled this flat nose 100% reliably, but it was obvious to me that all of my carbines would cycle if a very small amount of feed ramp throating was done to each carbine—these carbines were designed to feed round nosed bullets originally and a flat nosed bullet is a late development so, never rely on any ammo in any gun, till you test that very ammo in that very gun. If you are not willing to do some feed ramp modification on your carbine, you may want to relegate this load for use in revolvers.

This load worked perfectly in my single Ruger revolver. This load showed very good accuracy in each firearm it was tested in and the bullet is hard cast and gas checked and will NOT cause lead fouling in any normally operable barrel. We ran out of case/powder capacity before we could reach the advertised velocity of around 2100 fps, but still, this load is using a bullet that is 15grs. heavier than the standard 110gr. bullets, at or faster than the velocity that most 110gr. bullets are generating.

All three of these jacketed loads fed/cycled reliably in my carbines, but please function test your own carbines before you rely on any of these loads to save your life or the lives of loved ones…….always function test the exact ammo you plan to carry, in the exact gun, you plan to carry. Never assume anything when it comes to important matters……guns are ALL individuals.
