My grandfather used to reload ammo before he passed away, I'm not in any way advising this but he would use an allen wrench/drillbit type tool to
hollow out the hollowpoints, get a good bit of the lead out (only seen this done on a 44 mag), then take a undetermined amount of very fast burning
powder (I think it was called Black Cat) and pack it near the top, leaving a few mm's, then put a pistol round primer on top to cap the bullet and
seal it with clear fingernail polish.
I wish I still had the pictures but in a approx 2inch JC Penny catalog from the 80s-90s, it would be a hole in the front the size of a pencil or
so.
Then you flip it over....the last 200 pages was absolutly shredded, the hole would of been bigger than the size of the book..
Just hollowing out the center of bullets is somewhat safe, as long as you don't go too far and don't leave edges sticking out, just use common since
with the force of the powder expanding, pushing on the now weakened hole, it gives good results on pumpkins and water filled milk jugs
I inherited the said ammo after his passing and kept a few around just in case but if something drastic happened like the topic of the thread, I would
rather pull out the 12gauge pump or the ole trusty 22lr, with shims and a nice scope, you can knock walnuts out of a tree at ~75 yards and it's been
known to kill several deer in it's time with 1 hit to the lungs.
