    Really enjoy your videos. I think you are chasing velocity a little too hard. 2000 to 2200 fps is easier to get in my experience. I would suggest 4895. I have had good luck with it and conventionally lubes boolits in AR's.

    Skip the ball powders if you want accuracy over speeds.

    So would a flake powder be better or stick ? Because the only stick I think I have is varget

    thank you very much and glad you like them ! I'm honestly after accuracy more than anything, just trying loads that are supposed to group well. Elvis ammo on youtube mention using bother these and he was getting nice groups and figured I'd try. The high velocity is just a plus lol.

    Outpost 75 mentioned Reloaded 7. Do a search for his posts for details. I would absolutely trust his recommendations.

    Outpost 75 reccomend Reloader 7. If you search you will find the specifics. I would absolutely trust his recommendations. If I had varget I would give it a try. I used 4895 because it downloads well and was designed for gas operated guns.

    Stay with the 2015 add a dacron filler it will almost do away with the unburnt powder and improve groups.
    I shoot a Rock River AR with 24" heavy stainless 1-12 twist using NOE 70gr RN with 17.5 of 2015 and dacron
    Groups are 1 1/4" at 100 don't know the velocity. If I can I will post a pic of the target.

    Dacron Hmmmm I'm be seen black powder guys do something similar as far as powder compression, you happen to have a link to where I can get some ?

    Old pillow. Do your research before you do it. Easy way to make a plug and blow your gun up. I have tried it in several cartridges and is just too much trouble. It is better to find a powder that does not need it. Rl7 and 4198 works perfect for cast in 223

    Your varget will work fine. Start at 18gr and go up to whatever it maxes out at for jacketed. But you should find a load that shoots well down low.

    Its pillow stuffing, you can get it at walmart notions dept as a stuffing or in ½" thick sheet which is what I use, I cut the sheet into ½" squares making cubes
    its just the right amount for the 223 with 17-20 of 2015.
    DON'T pack it you want it be loose just so it holds the powder in place.
    I push into the case just below case mouth then let the boolit push into place.
    The exact amount of dacron is not important as long as it fills the airspace.
    There is a lot of info here about dacron fillers, just do a search.

    You want to weigh the Dacron just like powder to have the best results. 1.2grs was what shot best for me in 308win. 223 should be half that . You don't want to use too much either.

    I used to use old dog toys for my dacron

    It is usually all over my floor. I have a 21 month old Lab female that lives to "liberate" Dacron from stuffed animals!

    Watch vid, observe barrel 'smoke', mostly lead as you increase fps.
    Whatever!

    I compiled this a few months ago from various cast AR posts on here and elsewhere....would be interesting to know if any of your tests have been similar:

    There are several entries for fast twist 1:7...could we add what you've done so far here?
