I am not a pcp guy but a springer benchrest guy. But I am also a long time powder burner centerfire bench shooter at the Nat'l level. I think it important to keep the context straight. If we are talking 100 yds here a pellet will not compete as a rule with a slug or a .22 rf . Now a high end PCP slug gun will compete with a .22 rim fire, see post #10, and at times be even better. If you want all your groups to look like 1 ragged/ or not hole, you need to step into a powder burner like a 6 PPC. Regardless, for top end success at 100 yds it will not be consistently feesable without windflags unless you have access to a 100yd tunnel. Springer, PCP, .22 rimfire, centerfire powder burner........All different with different capabilities. If you think windfalls are a joke then there is a joke somewhere but it's not the windfalls. I saw the comment about I can't read or remember all the flags. Very simple, 2 or even one flag gives you a huge advantage over no flags. Never forget the big danger....You don't know what you don't know. But even worse......Your unwilling to learn.
