Mike ,
a few years ago i had a customer in California order 13 x3 packs of Silver Flames yes 13 packs . he was going after cape buff and wanted the very best broadheads available and was testing broadheads and was going to Test the Silver Flames with all the rest he asked if i was interested in what he came up with when he was done .i said yes and a few weeks later i got an email back with a spread sheet of his findings .i was amazed at how many blades he had crap written after , they weren't sharp out of the box ,weights out 20 gr from head to head in same package , they fell apart when they hit bone .
ps he killed his buff with a sliver flame and the PH Hunters he had asked him to leave all the 180gr heads he had with him .the Silver Flames were with in 1 gr of what they were marked --- herb
PS:this happened 2 years ago so i don't think anything has changed , just to expensive to throw out products that don't meet exact weight which is probably 80% or more and how many have grain scales or bother to check
