Ok, work be damned...

I went next door where I keep my bow and got all my inserts (the hot melt they were applied with did a poor job, they spun in the shaft so I took them out to re-insert with 24 hour epoxy).

The wasp and 100 grain steelforce fully seat on each insert. The 100 grain tip and 75 grain steelforce do not. The threaded shaft of the two steelforce heads appear identical, but apparently, they are not. The Wasp threaded shaft is actually about 1/16th" longer than the field tip that won' t fully seat.

I' m at a loss as to what' s going on...
