Re: Finally Broke into the 700 Yard Club
If you have recorded good DOPE, you should be able to put together a pretty good data sheet. Go to the G7 Ballistic Calculator, available here on LRH or on G7's website, and enter what you already have. There is a Validate Trajectory feature that you should be able to use to come up with a velocity. I got along for years with just the same information you already have, just by entering it into a software program and field testing until I had good DOPE at, say 100,300, and 600 yards. From there the software filled in the other ranges. I printed out my data sheets in 10 yard increments... that is until I started using G7's rangefinder, but that is covered in detail on other threads here.
As I mentioned earlier, I got tired of missing varmints by inches, so I started investing in more tools, and the knowledge to use them.
