[QUOTE="abinok, post: 62266, member: 16"] Ian, I will agree with you that the fishtails are challenging, and make a good spotter important, unfortunately I shoot without a spotter most of the time. The rifle im shooting only weighs 13.7 lbs, so it is almost impossible to spot your own hits. From a solid prone position it can be done, but youve got to be on your toes. TOF is about 2 sec. I used to use the deflection charts in the manuals as well, untill I realizd 2 things. since most of them are broken down into the "hours on a clock" format, you only have 4 referance angles. 0, 90, 30, and 60. As anybody can see, at 1350, the differance in those angles is huge. Once I realized that they were the product of the sine of the angle, I started getting firing solutions that were much more accurate. Anybody out there who wants to get a table like the one I made above, just use one of the ballistics programs on the market to get your inches/mph or moa/mph data, then multiply by the sine of the angle.
