Those of you that shoot Hammers, how do you deal with their very “loose” BC figures that they publish when truing your drops?
I wish they tried a lil harder to publish more relevant figures. The equipment is obviously out there. I shoot them in a couple guns because the gun likes them, but I’ve found their BC numbers to be a good bit off in my guns and it can sometimes take some extra tinkering to true up drops. I know I’m not alone as this has been widely covered. This is not to bash Hammer, but how do you deal with it?
What I do is knock 10-15% off Hammer’s published figure to start. Confirm my 100 yd zero and get a good MV average. Then I go to 5-600 yds and use that manually reduced BC number to start. Check my solver and dial up accordingly. That usually gets me close, but not perfect. Sometimes it takes a few more clicks to get confidently centered. Then from there I will true MV to wherever I end up on my dial and pretty much forget about BC.
This is more or less the same process I do with any other bullet, but with anything else I can usually start with box BC or better yet Litz’ BC’s (which rarely need much of any further velocity truing), and it gets me closer than it does typically with Hammers.
Is there a better way? How do you do it? Or what BC do you use to get started and then true your velocity? Or do you keep your velocity and true BC? I’d love to cut a few shots out of the process.
