I never tried wax bullets in my revolvers, but I did try .45 caliber rubber projectiles. The cap just didn't have enough power to make the use of them feasible.
So I tried "glu-lets." Still no go.
What I ended up using in my basement range was a glu-let ahead of 3 gr. FFFG with the rest of the chamber filled up with that Mooslum cereal, Ka-reem of Wheat.
The smoke wasn't bad at all, but I did kick up the ventilation so Kathie wouldn't complain.
