    7.62mm M1 reloads

    A note on Commercial cases yes they can be used, no they don't need there primer pocket reamed/swaged or cut. But the internal volume is larger so you will need too add +0.5 grains to the powder charges to maintain the same ballistic performance that mil-spec cases produce.

    FYI, the old saying goes, use powders in the medium burnning rates thats IMR-3031 fastest to IMR-4064 slowest still hold true today. I shoot with alot of Varget powder and it is a bit slower than the 4064 powder if you feel that Varget is too slow thats OK don't use them I won't argue, I feel that at there low charge weights they are a exceptable accurate powder. my.02

    All brass gets the same prep, Full Lenth resized, there overall lenth gets trimmed too the minimum 2.005 lenth, all primer pockets get cleaned and swaged if needed, the case mouth is then chamfered and debured, NOW this part is important any standard large rifle primer can be used but for safety reasons make sure its seated below flush. This prevents slam firing.

    Reduced recoil load for general plinking fun that can also be used for local 200yd Garand Games that let the 7.62 M1 play in. This is a great no wind load. Yes you rifle will cycle with this load.
    Bullet: Speer 125 TnT
    Powder: 41.5grs IMR/H-4895
    Primer: Any standard large Rifle
    Coal: 2.70
    This load has a M/V close too 2800fps and it cycles the M1's action just fine so there no worries here, recoil level is about the same as the Ar/15 nice and light, but be care full the 125 TnT has a history of flying apart before they reach the target when pushed up too 3000fps so don't hot rod them past this load level. For the Match shooter this load will shoot inside the 10ring at 200yds past 200yds they get cought in the wind and move to much.

    A step up in performance/accuracy is the 135SMK, upping the charge too 43.0Grs of IMR/H-4895 @ 2.75-2.77 COAL. At 200yds it will lick the inside of the X-ring, @ 300yds it will stay deep inside the 10-ring. On days with little wind its a 300yds rapid prone killer, recoil is about the same at the Ar/15 level.

    Sorry, I have no 147/150/155 load data as I don't shoot them.

    Any 168 HPBT
    Powder: 41.5 IMR/H4895 or 41.0 Varget
    Primer: Any std Large Rifle
    COAL; 2.80-2.83
    This is a clone load of M-852 LC Match or FGMM, its a great go to load for those when indout times and is my go to load for 300yds when there a little too much wind for the 135's, and is my go to load for 600yd slow prone with lite wind. it isn't at extreme for its pressure, M/V checks in at 2630fps if your rifle doesn't shoot this load well you have a sick rifle.

    Any 175 HPBT
    Powder: 41.5 Varget or 42.0 IMR/H-4064
    Primer: Any std Large Rifle
    Coal: 2.83
    This is a clone load of M118 LC Match or the current M118LR so it depends on how you look at things. If the wind is too much for my go to 168 loads, this is what I use, its the better windbucker M/V checks in at close too 2600fps over the chrono.

    And for Gods sake never crimp a bullet too the case mouth!

    FYI, The original load development was done in my Springfield Armory M1A, and they work just as well or better in a 7.62mm M1 Garand the M/V will come it a bit faster owing to the Garands extra barrel length. .

    Have fun load development done, go load some up and enjoy.

    As usual, great stuff!!!
    Speaking of 7.62MM M1 Garands, did you have any mechanical issues with yours? I find them to be tricky to work on and have to be tweaked just right to be reliable. Maybe the ammo comes into play along with the other issues they generally have.
    Thoughts??

      No its has been easier too tune than my M1a, some things are similar and others different, if I had too rate the difficulty level I would say its the same as falling out of bed. .

            Varget was developed for the FN FAL originally.
