CXRs Wrote:Hey all, so I've been playing with my PSA 20" Grendel lately, and found a load that is giving me insane accuracy, but I dont have a chrono to check it, and I've got no idea what kind of velocity to expect.
I've been loading 27.2 grains of Benchmark behind a 123 SST, and according to Hodgdon's website and my Lee manual I should be getting around 2400fps, but factory ammo like the Black and Custom come in around 2550-2600fps. Is factory ammo that hot, or are the numbers wrong on my reloading manuals?
It's weird, Im also getting better groups with Benchmark(1.1MOA 26.8) over CFE223(1.3MOA 30.5g) with 123SST...then on the flip side getting better groups with CFE223 (0.4MOA 33g) over Benchmark(1.1MOA 28.5g) with 95 Vmax.
Based on general recommendations I've seen throughout the WWW, I would have thought the results were juxtaposed, but I have confirmed my findings a few times.
