- Well, I guess we can try some SS109 if we can find it, but I wasn't
- very impressed by it at a shoot a year or so ago - a couple of guys had
- just got some SS109, and were shooting it at a junk disk brake disk that
- we happened to find. The disk was maybe slightly thicker than 1/4"
- (from memory), and their shots hitting it at a range of about 10 yards
- only made slight "smears" on the surface, with no penetration at all.
- (I know, this wasn't a very safe distance to be shooting at metal, but
- we had the disk slightly inclined against a sand backstop and we were
- shooting from behind a vehicle - don't try this unless you are willing
- to accept the obvious risks)
-
- (flame suit on):
- Then I demonstrated what a REAL rifle, rather than a mouse gun,
- could do - one 270 grain soft-point at 2700 fps out of my .375 H&H
- totally destroyed the disk - the side I hit was shattered into many
- very small pieces, and the rest was broken into larger ones ;-).
