PPB bullet expansion
« on: March 02, 2003, 10:04:18 AM »
How much expansion should I expect - or try for - in my PPB's.  They say jacketed bullets expand to 2x sometimes, - shouldn't I expect more from PPB's?  I shoot 30 cal.

Jpuke:

I just tested a lube that Someone posted,and took a big box of wet news paper for recovering the bullets,

(by the way that lube workes better than mine.It stays for the whole length of the barrel.)


The mould was made by Tom Ballard of Montana.The length of the bullet was 1.451 long,and it tapers from .450-437at 550gr. The paper was 2 wrapes of 1.5 thousants of rag paper.The velocity was 1190 fps range was 200yds.The bullets recovered were.685 long and 1.012 wide in a perfect mushroomThe alloy was 30-1 lead tin.
The caliber was .45-70 with 70 gr 2f seated to an OVL. of 3.216" with a .035 wad and a 1/8"grease cooky.
5 shot groupe was 2- 1/2".I was satisfied :grin: Lp.

I've got a 45-70 bullet on my bench that I recovered from a doe that entered about 2" right of dead center on the south side end and stopped just under the skin at the north end.  Went through a pelvis bone and still held together.  Started out at 421 grains and ended up at 409 grains.  Alloy was about 1:40 as near as I remember.  Flatted out to a smidgen over an inch and was mushroomed back around the base.   Purdy!

Wasn't as bad as I thought it would be.  Missed the stinky part, lost only part of a ham where the bone disentegrated.
