I was wondering if the m223 scope took all of the looking at charts or trying to remeber everthing.
A chrono. would be handy though for setting up my bow for hunting.
A crono is also necessary for figuring bullet drop. If you don't know how many FPS your bullet is going, you can never figure accurite bullet drop unless you set a target at every range you want to shoot at with every bullet you want to shoot.
With the FPS in hand, even the $12.00 Lee ballistics program will figure the exact bullet drop as long as you know the caliber, BC and FPS.
The Crony cronos start at about $90. will work with everything from a pellet gun to arrows.
They are a great investment. Books and bullet packages are never right or even close sometimes as to FPS, the only way to know for sure is to shoot over a cronograph. They are great for finding the most accurate load also.
If one load has a spread of 75 FPS between 10 shots and another 14 FPS, guess which load will be the most accurate?
It is great for finding the best lot of 22 or .17 rimfire ammo as well as knowing when your rifle barrel is starting to get shot out.
