Has anyone tried this CZECH manufactured double base, spherical powder as a substitute for Accurate 2520?
Given that AA2520 has become extinct (temporarily I hope), I just ordered two pounds from Powder Valley to wring out in some new wildcat cartridge/barrels ---- interested to learn just how close the burn rate is to 2520, temperature stability and how clean it burns at upper pressure levels before I get started.
Anyone using or have used this powder, please chime in ---- thanks, Tooter
