[QUOTE="4ked Horn, post: 97987, member: 11"] [b]I\'m gearing up for a ladder test. I have a few ?????s[/b] I had a Q for the ladder testers here. I am going to do a ladder for my brothers .338 win mag and my nephews .243 win. I ran ballistics on an approximate high and low velocity to see how much room this would take up on the target paper. In other words, how much the velocity increase would raise the trajectory. I came up with a number of around 7 inches for the .338 but it was only 2 inches with the .243. Both numbers were derived by running a ballistics program and only changing the velocity. I left the zero distance at 100 yards. Question numero uno: Is my logic flawed to the point that I am way off base? Question numer zwei: If the guns were capable of shooting 1/2 MOA at 300 yards won't there be a very good chance that 19 shots spread out over 7 inches (.338) or 14 rounds over 2 inches (.243) will be all over the place in a funny looking little vertical cluster? What am I missing? [img]/ubbthreads/images/graemlins/confused.gif[/img] [/QUOTE]
