Yes I have looked at it. Just need to define a few items and let it roll. Do some trail and error print it in black and white to figure out the text/font.
Colors are up to you, probably only need two color bands for an air rifle, depending on your zero. The chart at the bottom is based on your DOPE, clicks/yardage from your zero.
I've got a hatsan Bullboss .22 with a DonnyFL Ronin on it, I can hear the hammer spring and pellet hit the target. From about 10 feet away you can't here a thing .
I like it, but I don't have any other PCP's to compare it against. Without the donnyFL Ronin or sumo it's not really backyard friendly. I'll probably add a a huma reg to it over the winter .
Missed a few times.. 6 house sparrows that I left in the brush for the cats, couldn't find a 3 of the 6 chippers that I picked off in heavy brush/limbs the squirrel was raiding the oriole feeder. All fromthe comfort of the couch . 22 Bullboss shots from 8 to 29 yards .
Looks like a 30 or a 257 is in my future! After I get my 308 powder burner sorted. Not sure they will be realistic for where I hunt currently, 1 out of the last 15 deer has been inside 100 yards. He snuck up to 29 yards on me in the fog opening morning .
