Lee 200gr cast results
I did a function and penetration test with the Lee 200 gr gas checked bullet yesterday. Alloy was water dropped wheel weights, with 10.5 gr 1680.
Rounds were supersonic and point of impact was the same as my 220 HRN sub load at 100 yards. No problems cycling whatsoever across the 10 rounds fired.
Informal "penetration" test done with 3/8 OSB in front of a 2 gallon water jug and 2 2x6s leaned against the water jug at 50 yards. 220 SMKs and 220 HRNs both drilled caliber size holes through both 2x6s and didn't even knock them over.
The Lee bullet struck the first 2x with a slight wobble and exited COMPLETELY SIDEWAYS and embedded itself rear-end first in the second 2x. That's a 90 degree revolution in about the length of the bullet!!! Seems to me that this one would be set to "puree" in a test media of the swine variety.
Also, I'm now a firm believer in the water drop method of heat treating wheel weights. The bullet was essentially undamaged, with only rifling marks and possibly a (very) slight bend in the shank. The gas check was still attached, and all of the lube was used up.
Will try a softer alloy (ACWW, WW/PB mix, etc.) next to see if I can get some deformation in addition to the tumbling.
It doesn't get any cheaper to load the whisper than this.
Anyone else have any results to share?
