Teapot
The factory stuff is good but it is expensive and underpowered and I just want to have a little bit of fun experimentation. [/QUOTE said:
Never buy reloaded ammo from an unknown source!!!! I know of two guys that lost parts of their hands and faces buying reloads from an unknown vendor and a gun show twenty years ago. Factory ammo is load to SAMI specs and the maximum safe pressure levels. I've never bought a box of factory ammo that was under powered, unless they were designed as a reduced load.
Half the fun of reloading is working up a safe load for "your gun". If you don't have the time or patience to learn how to safey reload, then stick with factory loads before you blow up your TEA CUP!
I would suggest having a knowledgeable reloader teach you how to properly & safely work up a load for your rifle when you have the time to spare!
