Its not really relevant to handloading to know how much powder is in a rimfire round.
So you want to know how much powder fits in the case or how much you would use to properly load each ?
Bullet weight changes the amount you can safely use....heavier bullets - less powder.
For the rounds listed normally not less than 5 gr. and not more than 18 gr. ...there could be exceptions.
