    My dad and brother were at a local supply shop the other day. A guy there was telling them that he takes 7mm mag brass, fills it with lead shot, swages it down, and loads it as a projectile into a 50bmg case. He using this on whitetail deer with tremendous effect, as the 7mm case with the lead shot fragments. Has anyone heard of such a thing? Seems WAY out there to me.

    We do the same thing down here in Texas, 'cept we don't use the lead shot in the case. We use a mixture of salt and cayene pepper, cause we have to take such long shots, the deer may be spoiled before we get to em without the salt. The pepper gives the meat a better taste, too.


    Ya'll may think I'm jokin, but I'm serial, I mean serious.

    Seems hard to believe. I don't know what the twist rate is in a 50BMG, but if it's 1 turn in 12", and assuming he is using a reduced velocity of say 2500 fps, the projectile exits spinning 150,000 RPM. Seems hard to believe that the combination would hold together and achieve any kind of accuracy compared to a swagged conventional lead/copper bullet.

    After a little research, the common twist rate is 1 in 15", which means the projectile is spinning 120,000 rpm. The gyroscopic imbalance of that proposed combination would create a most inaccurate projectile. Good grief, a set of swaging dies, and there would have to be many to be done correctly, would cost a fortune. Why not buy new bullets instead?

    What you get with a swaged bullet filled with lead shot is called a frangible bullet. They are absolutely devastating on soft (flesh) targets. Using the proper jacket, (not sure about a 7mm.) you can get very good results from small bore right up to and including .50 BMG. Police and Prisons use a variation on this as there is little chance for ricochet or secondary penetration. They will even come apart on little cartridges like .25 ACP.

    You can check some of the commercial bullets available for reloading at the following website http://www.genco-inc.com/products.htm#frag or click on the avove link for info.

    I have a .45ACP carry gun loaded with this stuff and a .38 spl with +P loads for a home defense gun. (If I don't get them with the pump shotgun first.) I have seen the test data on this product and accuracy is better than I can shoot. If you reload pistol and would like an exellent projectile for self defense or home defense you can order a small amount from Genco.
