This file consists of some equations (made it years ago and need to check my math) and a sheet with 4 cards that you can input projected drops for a particular caliber and rifle or that you can use for dope. I made it so that it could fit in one of the football quarterback play call wrist flip thingies.
This sheet is a blank form of an excel sheet I created to use to track the cost, additions, repairs, and pictures of my firearms. The fed form the gun counter guy gave you sucks. Hopefully, this is of some use to you.
This is a quick video how to use ATF eForms to register your pistol with a stabilizing brace that is now a rifle with the ATF for their silly rule. I apologize, no time to edit, and I ramble a bit.
