Hi everyone,New guy to the forum needs some advise on the 20 Var Targ. Specifically, What kind accuracy can be expected at 100/300 yards? Is it difficult to find what works and what doesn't. How about twist rate and barrel length? I don't mind spending time at the loading bench to bring it all together but I don't want to wast my my time on a rag either. Thanks. DWM Jr.
