alright guys, any experience with a .223 bushmaster pushing a hornady 68 bthp match with varget or benchmark? looking for 3000 fps. gun is a bushmaster varminter, 24 in barrel w/custom muzzle brake/comp. brass is lake city with a choice of remington match or winchester primers.

thanks

.223 Rem 68 gr. Varget {26.0grs} 3000 fps drop 10% for LC case's... this is a max load in my Bush.

i'm guessing the drop is for case volume? you running them compressed and what type of brass? i can use whatever i can buy, i just want to reach targeted velocity with accuracy. i just have thousands of lake city laying around.

I used Winchester brass, yes the 10% powder drop is for Military brass. If you load the 5.56mm Mil L.C brass with Varget {23.4grs} you should reach 3000 fps... easy, keeping in mind that's still a max load and you might want to start a little lower.

went to the range today. loaded 3 @23.0, 23.2 & 23.4 respectively. avg velocities were roughly 2870, 2880 and 2895. first and last groups were 0.60 and the middle was way off. i'm pretty sure i moved a bit. still not what i was looking for. any other recommendation to push a 68 gr bthp 3000 fps with a 1/2" group? cost isn't really an issue. new brass, different powder, different shooter, whatever it takes.
