Worked on the range today building doors. When we took a break I shot 3 of the 358318's that I made the other day. It was raining softly and the only area open was 50 yards. I used a bale of phone books 10" thick taped together and hung them on the rail at 50 yards. The shots went exactly where I aimed them ! 1st at top right ,2nd in the middle and 3rd in the bottom left of the bale. I got 7 to 8" of penetration with another inch or so of damaged pages. The bullets started to expand at ~1" and continued till they stopped .There was a wound channel of 1 to 1 1/2". I only recovered 2 of the bullets and 1 gas check. Also a LOT of fragments. I have not weighed the recovered bullets yet but expect them to be around 100 grains after starting at 240 before gas check and lubing. The books were DRY, and performance is quite similar to bullets I have flatnosed by hand.
Velocity is 1995 fps. I plan on a little more playing with this bullet and shooting WET phone books for comparison. Merry Christmas!
