    I want to start reloading rifle starting with 308 win for a M1A.
    The bullets are 168 Sierra match.
    I got many years ago from the CMP.
    I would to like pick a power that I can use for 308 win, 3006 for M 1 Grand, 223 for AR 15 and M1 Carbine.
    Is their a power that will work for all of them.

    Varget might work.

    I use Ramshot TAC off all but the carbine already and am very happy with its performance.

    The M1 Garand is the most sensitive to port pressure so stick with IMR-4895, H4895, or IMR-4064. Those are also good powders for the M1A's port pressure needs and will work fine in the less sensitive AR-15.

    Sierra has a fine write up on the challenges of service rifle reloading: http://www.exteriorballistics.com/reloadbasics/gasgunreload.cfm

    A very detailed guide on reloading the M1A for match shooting: http://www.zediker.com/downloads/14_loading.pdf

    An excerpt:
    The staple M14 bullet was (still is, in a way) the Sierra® #2200. This 168gr bullet is the first to try: if this bullet doesn’t shoot in your rifle, the weapon is cursed. More than I know anything else in life, stick 41.5gr H4895 in an IMI® case with a CCI® BR2™ primer and cap it with a #2200 to 2.800 inches oal. Done and done. Then go messing around with “better” bullets now that you have a sure thing to return to. Use 40.5 grains if you want. I did for 200 and 300.

    4064 mainly because its more available than most else, It's good powder too.

    +1 on the Sierra info about loading for gas rifles, especially the M1.

    Keeping Sierra's advice in mind, you might then go to the Hodgon reloading data center where you can compare several powders for your cartridges from Hodgon, IMR, and Winchester brands all at one go.

    Thank you Steve M good info. I have reloaded for the M1 for over 20 years. I shoot the M1
    in competition. The M1A I have reloaded for but not as much experience with as the M1.
    I have used both IMR 4895 and IMR 4064 in these rifles. I have found the IMR 4064
    to be a bit more accurate. My favorite M1 load is (30/06) LC brass, 168 SMK and 46 grains
    of IMR 4064. My 308 load is LC match brass, 168 SMK and 40.1 grains of IMR 4064.

    Favorite powders for the 223 are W 748 or H335 for 52 or 53 SMK. In the heavy bullets
    77 SMK or 80 SMK I prefer Varget or VihtaVuori N140.
    As with any load data, you should always check with a reloading manual.
    I really like these manuals for one caliber.

    Ron, what kind of fps speeds are you getting from your heavy bullets using Varget or N140? Is it an AR or a bolt gun?

    I shoot an AR. The 600 yard stage of a High Power Rifle match I use the 80s loaded long
    just off the lands. Velocity? Never measured them. The 77 SMK load is extremely accurate
    at 300 yards. I know of other top shooters using the same 77 load.
    My load for 80 SMK is Win. brass, 24 grains of VV N140 or 24.3 grains
    of Varget. Weighed charge. Remington 7 1/2 BR primer. 2.860 OAL .This is a max load!
    For 77 SMK , Win. brass, 23.5 grains of Varget. 2.260 OAL. 7 1/2 BR primers.
    The 77s are loaded to magazine length. Rapid fire prone stage 300 yards.
