We bought a foreclosure 2 years ago that sat for 5 years. As a result we have been battling wasp, carpenter bees and yellow jackets every spring and summer. Last year we armed ourselves with spray and tennis rackets. A very narrow margin was held but overall we won the battle. This year we started early with traps and taking out all previous nests. But it has not been enough to win the war for good.
So it was time for a more powerful weapon. One that could take out carpenter bees from a distance longer than a tennis racket. What better than revolvers
After some testing with different powders, charges and projectiles I found a pretty good load:
38 Special Brass
CCI SP Primer
2.5gn Red Dot (of the Hercules vintage)
Wad made from automotive gasket material and a spare case
Grits (Jim Dandy Quick Grits) filled to the top, tapped down and re-filled
Another wad on top
Crimped with Lee FCD to a pretty good roll
Results - at 1-4 feet it blows a carpenter bee apart, 5-10 it knocks them unconscious/dead, out to 15 it takes their wings off. Only issue I have found is that it will screw up the porch screen, which for now is fine as it needs to be replaced.
Overall it is turning the tables. Just need to find something for a wad that doesn't require me hammering them out, that is the current slowdown in the loading process. Also want to try and design some 12ga loads for taking out large wasp nests.
