Anyone know if .22 ramset blanks will work in a .22 rimfire single shot rifle? I think the brown colored ones are the lowest power.

I need some .22 blanks, ramset, hilti or otherwise for some INDOOR gun puppy training. I have one of those .22 cal Erma starter pistiols, but finding those small acorn-type blanks it takes is like finding hens teeth.......

Been shooting #11 musket caps, but they are not loud enough.
