Howdy,
WHOAAAAH! HOLD ON FOLKS!!!!!
Squirrelduster, you are getting very good advice from well meaning folks, BUT they don't have enough information. All these well meaning, expert reloaders are ASSUMING that you are reloading for a bolt action rifle. You did not specify in your original question. If it is indeed a bolt action, then feel free to proceed right along; HOWEVER, if it is a semi-auto, pump, or single shot action hold up there.
A gas operated semi-auto really needs a powder on the order of 4895 to make the gas operated action work correctly. A slower burning powder (like the ones that have been recommended) will harm your rifle after too many shots; in fact, your semi-auto action probably will not cycle correctly with a slower powder.
I have no experience with single shots, but my 'smith tells me that they should be loaded similar to a sem-auto.
What ever you do, work your loads up carefully from a minimum load. Most important of all...... ENJOY THE PROCESS!
Good shooting.
