i see no point in light charges anyway- maybe in something light but i don't have such a beast in my inventory- you have to use enough powder to drive back the slide and engage the sear, and that establishes your threshold unless you're using a revolver- the only revolvers i have are ruger redhawks in 44 mag, so i'll probably NEVER go down that road- if i'm carring a rifle it's for hunting big game anyway, or the ar for target, or 22 for gophers
