Remember, generally speaking slow set glue will be more brittle than a slow set glue. I have had a heck of a time getting glues to stick to the inside of kinetic xt's and I've tried everything. The HIT epoxy, loctite 24hr, some pine ridge fast set stuff, you name it. And I have wire brushed and cleaned them well. Like I said earlier, I accidentally set one of the brass HITs too shallow with the AAE Max impact, and I CANNOT get it to move for the life of me. I have used the drill bit method and everything else I can think of so far and it will not move. Just my experiences here fwiw
