Looking for Surefire slug ballistic data for Chairgun
What data, besides weight and caliber, do I need to feed Chairgun to get a accurate Bell Curve o for the Surefire slugs?

Thanks for the info Charlie. Will try it out.
Joe,
I really like the Handloads.com site, but it does not give me MOA trajectory information and Chairguns does.
The MOA calculations are what I use for my Leupold/Holland combination and gets me within a inch or so of any range from the muzzle to 250 yards with the Haley.
Took a while to figure it out buit once I did it was a watershed of information.

Good info Charlie. I will use this myself, thanks.
Lifo,
It took me a while to figure out how to work Chairgun with bullets.
The flight pattern of pellets and bullets is dramatically different, as such just entering in the wieght WILL NOT WORK.
You will need to get the Ballistic Coefficient, you can get that easily from Handlads.coms ballistic computer. BC varies with speed, but this will be close enough for what you need and the ranges we shoot at.
Go to handloads.com, choose the ballist computer chart setting, on the left hand side is a place to enter the bullet weight in grains and diameter, then drop down to the design and enter SWC which will pretty much cover wadcutters.
Once you have that BC, you can use their system and get lot of good data easily, or you can go bck to chairgun.
In chairgun you need to go into the 25 caliber pellet chart, and make a new entry using that BC you got from Handloads.com, once you enter that, you can obtain the information about the Jerry’s slugs you need.
I hope this helps,
Regards,
