The thicker paper allows for more of a chance for the bullet to not be seated straight. 9# onion skin works very well. If the bullet is not straight at the launch then where it hits is anyones guess. Ron
Ron,
Are you factoring in the paper? Being a machinist all my life, I had to convert mm to inch and inch to mm frequently.
To convert mm to inch, divide the mm by 25.4, but I'm sure you know this. Thought I'd post it in case any others would like to know.
11(mm) / 25.4 = 0.4330
To convert inch to mm, multiply the inch (as a decimal) by 25.4
1/4" (.250) x 25.4 = 6.35 or slightly over 6mm, which is .2362
