Thread: Chronograph thoughts

A lot of the long range guys set the rifle/scope combo up using one fo the several decent chrony's on the market. Then go do some shooting to gain some data. And most do their verifying at 600 for speed. Then once thats sorted, they shoot at 800 to verify the BC. I wouldn't be shooting at 200 for verifying, just not far enough to give credible results.

Setting up your CDS dials is not a one day, shoot some boolits, type of exercise. The more boolits fired, in varying conditions, the more credible your dials will be. I've seen a client use a guides rifle that had a CDS dial supplied using sketchy data, supplied on purchase, not after some time. And at 500 metres, after a 2 hour wait, the client shot a bull tahr, dead as. Was a good time, lots of back slapping and smiles all around. On finally getting to the tahr it had been shot cleanly through the neck. BUT the client had been aiming centre mass, centre of the boiler room, had a good rest and bipod, had time to settle in to the shot. This wasn't his first rodeo, and that shot was a good 30 cm higher than he aimed and it all came down to shit data being supplied for the CDS dials.

Take your time, verify your data using lots of distance, and then order your CDS dials. The results will be worth it.
