I have a S&W 631 that is in .32 H&R Mag. So it can also fire .32 S&W and .32 Long as well. So I have been saving up my Arnold Palmer's Half/Half jugs, half ice tea and half lemonade, and filled them with water. Didn't have a box but lined them up on a bench and shot from about 15' away. Was actually surprised by the .32 S&W.
631 and the rounds I will be using. L to R, .32 S&W 78gr LRN Norma, .32 Long 98gr LRN Magtech and .32 H&R Mag 95gr SWC Federal Classic.
First up the .32 S&W. Surprisingly made it thru to the third jug cracking the back but not entering the 4th.
Found in third jug, very little damage.
Next .32 Long. made it to the 5th jug.
Found in 5th jug with quite a bit of damage. Lots of gouges and a flat spot so at some point it must have started tumbling.
Only had 6 jugs left so set up a wood block at the end hoping to catch round but it just nicked the edge and into oblivion.
Amazingly it went right through the handle of the 5th jug and never touched it.
Luckily I had my 66 with me and this is the aftermath of a UPC 125gr JSP .357 mag. Most of the jug is on the ground to the right.
Close up of last jug.
Long day at the range for the 631. Had three box's of .32 ammo in various configurations and of course I had to shoot them up.
So in conclusion, not sure any of this really proved anything but I had a great afternoon shooting.
