My info may not be what you need exactly, however here goes. I have used the the tusker concord taken down to 145 grains. they fly just like field points, just as silent. I have split 1X6 boards with them ( not on purpose) and shot a doe at 35 yards. I got a complete pass through then split a sappling on hte other side of her. She jumped, walked sixty yards, laid down and died. She was so bleed out it was amazing. We were in a steep valley and I could not drag her out ... so I put her on my back and walked her out. My point is there was only minor tallow on my back, no blood! I split two ribs on her and had the "S" looking entry and exit.
The head is still sharp. It is in perfect shape. It is strong, quiet, sharp and accurate. My 145 grains do a good job. I also shot a 250 russian sow with one and took the top of her heart off. That head is still sharp as well.
I hope that helps.
Bob.
