I know its not needed but it seems to help lower my extreme spread on velocity and hasnt hurt my accuracy, if anything its tightened up groups some. I checked all my brass for pressure signs and it looks fine, gonna do some more playing with it today. Im thinking about trying accurate 2200 powder since it doesnt take as much powder and get close to the same velocities in the book. Im wondering if the faster powder will be better with the shorter barrel
A2460 is another good alternative double based spherical powder in that weight class. And supposedly, it considerably more temperature stable than A2520.
Still doing load development with it in the CZ 527 but, Ive already hit 3074 fps with 90 TNTs out a 23.5 barrel with zero signs of pressure on the brass!
