I've been using the same Saf. 5 shot loader for J frames for 20+ years without a hitch. They are smaller than HKS and load much easier into the charge holes IMHO, and there's no fumbling with "do i twist it left or twist it right?"
When I bought a 686P last year I contacted Saf. They do not now, nor do they have any plans, to make a 7 shot loader.
I have both Saf & HKS for J frame 5 shots, and have "test-loaded". Saf is better everytime and that's what I carry for the J as primary reloader.
