Thanks Randy. Along with JC's, that at least two weld breaks on a Deadhead so far. You use the plural 'deadheads'. Did you have that on more than one? Was it (or they) newly acquired Deadhead(s) or old head(s)?
Tom, the 190 grain Grizzly (and newer 160 grain) are not 'overly hard'. They run right around R 52. They need to be AT LEAST that hard to get the maximum benefit from the single-bevel and to prevent BH damage on hard tissues. The 'old' 160 grain Grizzly, at R 50, bent on bone far too easily, and rolled the edge easily when the bevel was down at 25 degrees.
The 190's and new 160's are 3 to 6 Rockwell points softer than most quality knives, but are also 4 to 12 points harder than most other commonly used broadheads. The harder steel responds better to the sharpening techniques you would use on a knife. That takes more time, but you end up with a stronger and better cutting edge that retains its sharpness throughout the penetration of the animal, even after a bone hit.
Still looking to hear from anyone who's damaged a 190 Grizzly on animal tissues.
