    Hello,

    I'm looking for some help on some loads - I've never done .25gr in any of my loads and was wondering if that makes a huge difference?

    Also do you know any loads I should try? As you can see by my load data, I show you twist and barrel length.

    My goal has been hit with my Cooper, but I'm still looking for .250" with my AR-15.

    Thanks

    Attached I have LOAD DATA, no pictures of groups sorry.

    That's pretty awesome shooting. ...especially with an AR.

    Perhaps you should sign up to be a sponsor here?

    A sponsor? I just shoot prairie dogs lol. I'm the type of person that wants to get as much out of everything that I can. I only load my rounds on a CO-AX press, with Redding Comp Dies, etc... I put alot of work into my loads..

    Here is a pic of my cooper and an old pic of my AR - I'll get new pics of the AR when I can, it has a few more additions - even tho you can't tell it has alot of JP parts, it does :D. I also have a Les Baer bolt carrier... many little things in there...

    My AR now has a Magpul PRS stock with mono-pod - Tubbs CS Flatwire Spring - Lower scope rings - Ergo Grip - Barrel De-resonator.


    Anyways - back to the loads :) Any suggestions?

    For me, I use 24.7 grains of H335 behind 53 grain varmint granades, they give me the best accuracy.

    Really? I never seen a varmint grenade as accurate, is your AR 1-9 twist? What kinda accuracy are you getting at 100yrds?

    1-9 twist. Rock River with a standard profile barrel. I am getting .75 with it. That H335 powder works well with ALL light weight bullets. You could try throwing in a 52 grain SMK in front of that charge and try the results.

    .750 - Did you look at my pdf for the AR-15? That's about my worst group....
    Maybe you should take a look at some of my loads and do some more testing in your gun, with my loads :)

    You probably have a much nicer setup than I do. Mine is the El Cheapo AR. Sorry, I thought the PDF was just a picture of groupings and not actual load data.
