Received some of Lehigh Defense' 174 grain Controlled Fracturing bullets in today. I have been looking for something that would be effective in the subsonic range. I loaded these up with 10.7 grains of A1680, to 2.200". Shot out of an 8" AR-15, SBR with 762-SDN6 silencer attached. The rifle functioned with each shot. I put up a paper target and covered it with saran wrap. 6 inches in front of the target I put two 17 oz water bottles, then shot through the bottles. The center hole is the main part of the bullet. The two outter holes are two of the "petals". The third petal hit and stuck into the table I was using. I managed to recover all the pieces. I will be leaving for work tomorrow, but hopefully when I get back the weather will be right for me to break out the night vision and see what these will do on hogs. Might get a chance to test on a deer this year as well.
