The perfect whistling point

[DesertDude]

I made up some 125gr Zwicky 4 blade Eskimo's with a 100gr steel BH adaptor. The BH adaptor is to short. It leaves a hole where the adaptor ends. Thus the Perfect whistle..........The first shot made me chuckle.....Got a good laugh out of it.......

[JRY309]

Just fill the hole with a little bit of epoxy.I have a whisling point a the first shot into the foam target filled it with the foam and no more whistle until I cleaned it out.

I filled mine with silicone caulk and it stopped.
