Kelly, if you re-read my original post you will see that i was not "broadhead testing". I stated such in the post as follows;
I shot two of the 190s into a pile of bricks out of a 60# compount on a wood shaft total weight 675 grains.
I was testing the efficacy of using minwax wood hardener to "foot" the wood shaft.
My guess the results you showed in the first couple pictured were from using too short of a point taper. On Ribteks one needs to use a longer taper so that it fully seats to the bottom of taper. Same goes for all other glue on style broadheads.
No, they were fully inserted.
I did this test at a time that ribteks were being bashed because many were stating that hitting game in a bone would result in what you see in pic #1. I never viewed it as a test that would duplicate hitting bone. I actually expected that what happened would not happen! It did happen, however, the results with the hardened shaft make it pretty clear that even with POC the "problem", if it exists, is easily mitigated by footing the shaft with the minwax hardener.
The third and fourth phots prove that. They also show that the ribtek is tough. Hitting bricks out of a compound at an angle did produce a bit of bending in the head. Most bow hunters will readily realize that it's not going to happen on bone.
I have a pretty good supply of 190 ribteks and pretty much plan to continue using them. Am considering using the 200 grizzley to gain the single bevel MA which would be advantageous on larger animals. A shoulder injury has me shooting lighter bows these days and I look for every advantage possisble.
Another thought is to convert the 190 ribteks to single bevel. It would give up some weight, but that could be made up by footing with a heavy hardwood and inserting a heavy weight in the footing. For my state it also must retain a width of 7/8th inch so that is a factor too.
