Hatsan Harpoon
ShakySarge:
I just ordered some Tenpoint aluminum bolts with the .305 id. I’ll be using quick set epoxy on the inserts and will let it set overnight just to be sure it set properly. I should have numbers and accuracy testing in a few days.
screwwork:
Matt,
Did the quick set epoxy work for you?
On my Prod arrow gun, I was blowing out the field tip and inserts like crazy, I used Loctite 609 retaining compound with Loctite 7471 primer on the arrow & insert and finally some success without shooting bolt parts everywhere.
My Prod shoots 2219-20 bolts @ 444grs at 275fps = 74.5 fpe at the muzzle :o
Rob M:
insane, you could hunt rhinos with that thing
screwwork:
Yeah, the Hatson Harpoon is no joke for sure when it comes to launching bolts at almost 600fps.

The epoxy seems to hold. I have switched strictly to the ten point AL bolts and so far no issues with them as long as you hit the target. If you miss, that bolt and broad head or FT is as good as gone. It’s moving fast enough that you cannot see the bolt in flight even with bright vanes. You should be good with epoxy at the speeds you’re getting.
I haven’t shot it much since my last post due to a lost bolt is right around 7-10 bucks a pop. I lose at least one each time I go to zero it in.
