Benchmark powder for .223
Posted 03 July 2011 - 03:52 PM
If it's accurate, leave the load alone.
Anyone have load info using benchmark powder and 55gr bullets?
Using LC brass and hornady 55s I get 2950 with 24.9gr at 2.230". I'd like a bit more velocity. This is out of an 18" JP.

I may not be perfect, but parts of me are pretty awesome...

My load is 55gr Sierra Blitz King, 25.6gr Benchmark, 2.260 OAL, using 7 1/2 Remington Benchrest primers delivering 3264fps. I have used LS, Fed, and Win brass with no more than 100 fps deviation between them. I found the Rem benchrest primers gave me about a 200fps bump from std CCI or Winchester primers.
Also my brass has showed very little stretch or signs of head seperation and I have loaded the current cases (LS06 specifically) 2 times so far...moving onto the 3th time soon. My groups are usually about 1-1.5 inch at 200 yards...on a good day

Anyone able to do the math if the poa/poi is the same as xm193 for how fast my load is moving?
