The thread is old but with a question asked the questioner is sometimes referred to an old thread. Rimfire Central has its place which is rimfire rifles & handguns. I will not take away from this site though. Rimfire guys get around & good advice can be found here.
When you go to http://www.rimfirecentral.com/forums/index.php you will find many sub-forums. Simply look them over & chose the one which interest you. There is also a section for centerfire rifle, handgun & reloading. You will even find bullet casters there. Still their main function is rimfire.
