    I have a RRA 24" varmit rifle with a 1/8 twist. I loaded up a batch of Serria 77 gr Match Kings with IMR 4320 and got so-so results (1 1/4" groups @100)Is there a better powder for accuracy? What about Varget? I was told this rifle will shoot 1/2" groups with a decent load.

    I have a RR 20" SS upper.
    I don't remember the last time I bought factory ammunition. I role all of mine.

    These are my loads for the RR. Note, where I live, my ranges are short. My own target range is only 100 yards into the timber and I have to use the brush hog to keep the trail passable to a downed tree that I use for stapling my paper targets. With this in mind, I don't spend much time on heavy weights for longer ranges.

    50 gr DogTown HP (inexpensive from Midway USA) - 25.5 gr 748 - 3017fps
    55 gr DogTown HP (inexpensive from Midway USA) - 26.6 gr 748 - 3013fps
    75 gr AMAX (not as cheap) - 23.5 H4895 - 2677fps

    These are not loaded for velocity. They are loaded for accuracy.

    I also load for an AR180, mid 1970's Sterling vintage with an 18 inch 1:12 twist barrel that doesn't like anything heaver than 55gr.
    55 gr FMJ - 26.3 gr 748 - 2874fps

    So, yes, I reload for my black guns.

    Warning, these loads are safe with my components, as I combine them, in my weapons. This does NOT mean that they are safe with your components in your weapon. Always differ to published loading data from a source that is trusted.

    Error on the side of safety.

    Enjoy and be safe.

    The heavies like to spin fast. Rate of twist is one component, Velocity is the other. Twist rate does not stabilize, RPM's stabilize. 77 gr is at the upper end for a 1/8 bbl. You may need to up the velocity to get enough RPM's.

    my RRA national match 20" likes sierra 69grn bthp over 24 grains of varget or aa2230. both give very good accuray out of my rifle. 100 yards is about .5 to 1 moa open sights

    I shoot a lot of 68/69gr match bullets out of my RRA 20" Varminter with 1-8 twist.It shoots them great,but I usually blow the groups with 1 bad shot!
    These groups should've been in the .25 range,but I threw one shot off.

    I also shoot 75gr Hornady AMax/75gr Hornady BTHP Match bullets quite often with it,but they are shot in a single shot mode since they are far longer than magazine length.As you can see,I threw a couple shots off here also.

    [​IMG]

    I've never tried the 77gr matchkings,but I have shot the 80gr.I wasn't impressed with the results.The 75gr AMax/BTHP Match bullets shoot better for me.
    Now if I can fix my shooting problem. LOL

    Go right ahead Jon.Hopefully,you'll get results as good or better. THB

    I believe I used Winchester SR primers on those loads,or CCI's.

    My AR has never had a factory round in it.

    Best results for me...Hornady Match 75 Grain BTHP over 23.0 Grains of BL-C(2). I have a 1 in 7 twist rate. At 100 yards the holes from my three round groups touch each other.

    I think Varget would be a good powder for you to try. I have had nothing but great results with it.

    I have found Varget a good powder but i found a better one for smaller boar riffles and that is "Bench Mark" which is Varget but in smaller extruded grains. Both of them made in Austraila.
    F.K.

    P.S. I have gotten 3/8 groups with it at 100 yrds with a M4 14.5 inch barrel. I dont have the powder mesure right off but I think it's around 24 grns of Benchrest, 50 grn softpoit Hornady.

    Not a black gun, but a bolt in .223 Rem. It has a 1:9 twist and likes 55gr VMAX over H335 with CCI primers.
