Hey! you don't have a nail gun section!
So this'll have to do, at least until you set up a "Devil's Playground" forum (from the "Idle hands/minds are the Devil's playground" proverb)
Right on the box for nail gun ammo it says they are not to be used for firearms. Is this just a legal CYA or are there special issues to consider in using these blanks in guns?
A standard .22 blank for starter guns will send a .22 lead pellet for pellet guns down range just fine. The smallest Ramset .22 ammo is quite a bit longer, maybe close to a LR, so presumably much more powerful. (Well, presumably. I haven't tried to drive a nail using the starter pistol blanks.) But unless they are loaded with some different powder the pressure shouldn't be much different from a .22LR. And if used just as a blank, with no projectile, the pressure should never get even that high.
I'm thinking starter ammo pushing a .22 pellet won't be accurate out to 25 yards, although it will reach that far. So I'll need to go to a bigger blank.
Also, I have an old Stevens Crackshot in .32 Short (rimfire) that I'd like to shoot. I saw somewhere on the internet that rather than go to the effort of converting it to centerfire and using .32 Short Colt (I think that was the CF cartridge that would fit the chamber) you could drill out the base of that cartridge and insert a .27 Ramset blank to drive a shotgun pellet (or maybe it was a lead bullet for a muzzle loader. I don't remember). The .27 rim dia. is close enough to .32 that the rimfire firing pin would reach it and fire it.
I never got around to trying that. I'd like to say it was the warnings on the Ramset blanks that discouraged that idea, but really it was lethargy.
