Recently purchased a CZ 527 Varmint and have settled on the 39 SBK for coyotes, great BC on it, also..picked up RL-10X, Accurate 2230, Accurate 2520 and have seen some "pet loads" people have, just wondering what to do on primers.....not much locally and all I have are Remington 6 1/2's (1000) and CCI 450 (1500) do I keep looking or try one of these??
