Welcome to the board Mike. Popgun is correct that you can do a lot of "what ifs" in Pointblank software. You need to decide what you are going to ask the rifle to do and choose a trajectory that best meets that requirement. You will need to know the muzzle velocity and the ballistic coefficient of your 32 grain bullet and some other atmospheric variables and then you will be off to the races!
If you are going to poke holes in paper at a fixed distance or shoot p-dogs at 3-500 yards you will want a different zero point. If you are wanting to kill coyotes beyond 150 yards .... get a bigger gun....
Sorry Popgun I could not resist.
Let us know what you plan to do with the rifle and we can help you through the software.
