I can,t recall if it was Sarge or Gunrocket who, about a year or so ago wrote an article on how pointed bullets in a tubular magazine was pretty much a wives tale, in that, ballistically and such you couldnt get them to go off. I can,t find that thread and was wunderin if any of ya could help me find it or maybe re-post it Thanks |

I read an article in a gun book published about two years ago on this subject. The author did some tests, and he got one round to go off, but it just ruptured the brass case. There was no damage to the gun at all. I believe he was using .30-06 cartridges for his test. |

I found this info on Tubular Magazines: There are chances of detonations, but for two different reasons. (1). When loading a Henry, tilt the barrel enough so the falling cartridge slides down easily & don't allow the thumb tab to slam down on the cartridges already loaded. (2). On 1866's & 1873's, there's no more danger in loading them than Marlins, etc.; HOWEVER, in ALL rifles with tubular magazines, be sure to use a flat nose bullet! Eventhough the last sentence SHOULD keep you out of trouble, I still had a friend have a bullet ignite the next cartridge in an 1873 while shooting. When the elevator drops, the cartridge tends to move back rapidly (under spring tension) possibly allowing the next cartridge's base to contact the previous cartridge's nose harshly. I'm not a gunsmith, but I don't think there's anything you can do about that. Maybe I'm wrong & one of the other pards will correct me. |

There is a distinct danger if pointy bullets are used. I have fired squillions of shots out of lever/tube mag guns without problems. At one stage I had the bum out of my pants and only had round nose bullets. I fired about five hundred of them, but made sure I held the forend well up away from the action. I have heard of two explosions, both many years ago. I did not witness these but it would appear that they gave way near the action. I can't see why that would be any more dangerous than anywhere else in the mag, apart from the explaination above. Round nose flat points are the go, don't mess with anything else. I was sure glad when things picked up and I could afford a new mould. |

One thing that gets folks in trouble in tubular magazines, even with flat-nose bullets, is high primers! Primers must be seated flush or even a little below the surface of the head of the cartridge. A lot of folks don't bother cleaning the bottom corner of fired brass, but crud can build up and cause difficulty in seating the new primer.
A very important point to remember is that there is a distinct difference between Large Rifle primers and Large Pistol primers as to the length of the primer and the depth of the primer pocket. Dispite being the same diameter, .210" nominally, Long Rifle primers can be up to .009" LONGER than Large Pistol primers. (This does NOT apply to Small Rifle and Small Pistol primers...they are the SAME length. No, I don't know why.)
Never, ever use Large Rifle primers in ANY of the cartridges we use in Cowboy Action Shooting[tm], regardless of whether you are shooting the ammo in a pistol or rifle! Not even .44 Magnum. These use Large Pistol primers.
I seat my primers using a separate little bench press and check the seating depth of each primed case. Should be flush or slightly below the surface of the case head.
If these things, along with the others mentioned, are done, you should have no trouble with a tubular magazine rifle, whether a Henry, '66, '73, Marlins, Rossi M92's, etc.

I'm guessing you mean never use large rifle primers in any pistol calibre cartridges, regardless of whether they're fired from a pistol or rifle. I can't imagine there should be any problem using LRP's in a rifle cartridge we use in CAS like 30-30. H-F Hank[/quote]I have to disagree w/ this statement,if rifle primers are used in the rifles it would lessen the chance of magazine detonations because the metal in rifle primers is thicker than pistol primers,they are harder to detonate so this would mean that u would need to keep pistol cartridges seperate from rifle cartridges of the same caliber,also if your loading 38/40 44/40 etc the cartridge was originally a RIFLE caliber which means that rifle primers work fine in them,where u run into trouble is w/45 colt when it's used in a rifle which is a pistol cartridge.If you'll compare the thickness of the cartridge rims between a 44/40 & 45 colt u can see the difference visually w/out having to even measure it. |

Messages 6 thru 9 are what I found pertaining to tubular magazines from other sites. I hope this is of some help. Hopefully, Sarge will see this post, and clear up any doubts we might have on this subject. Gunrockets |
