Hi new guy, welcome to the forum!!! Congrats on retirement and the new pew pew!!! If your new to pcp guns you’re going to love them. My springers miss me and I thought they were the cats meow until my airgun buddy introduced me to the world of pcp’s! They are amazing!
So to answer your questions on zeroing distance, near zero and far zero you will want to find the velocity of your gun and the distance from the center of your objective lens on your scope to the bore of your rifle. Then plug these numbers into a ballistic calculator. You WILL need a chronograph. That’s a hands down. I went with a Caldwell with the light strip on top. Many like the fx chrony however at the time I wanted to save a couple bucks and I don’t regret it one bit. Do note with a chrony that uses optical sensors fluorescent lights can and will mess with it. The light strips help a lot but when I tune a gun in my basement I only leave the incandescent lights on. Step two find the distance of the center of the scope to your bore. Measure the od of your barrel with a caliper and divide that by 2 and write down the number. Measure the “bell” (the large section around the front objective lens) of the scope and divide by 2 write down the number be as accurate as possible. Again with calipers measure the distance from the bottom of the “bell” to the outside of the barrel and write that down too(do not divide the distance from the scope bell to the barrel by anything). Add up the three numbers and you have the distance from the center of the bore to the center of your scope.
The website with the calculator I used is:
https://shooterscalculator.com/point-blank-range.php?df=G1&bc=0.035&vi=915&sh=2&ts=0.25&cfa=on&alt=490&tmp=59&bar=29.92&hum=50 This will give you the near and far zero, sight in at the far zero.
Nowadays I use the StrelokPro app on my phone. After learning a tiny bit (a fraction really) I find the app to be indispensable. Wither you range by the parallax knob, with a rangefinder, or best guess it’s great to be able to put the range in and have the app calculate the moa, mil, or number of clicks you need to adjust the scope to be dead on.
My buddy Rob has many more years trigger time than me and just knows what amount to hold over or under when shooting. I’m not there yet so I use the ballistic calculator.
You may eventually want to look into a cheap compressor to save yourself a workout with the hand pump. It didn’t take me long to to start reading threads on the yong heng air compressor. Then came the air bottle. I didn’t buy everything all at once, just kinda one at a time as the money became available. The chronograph should be your next purchase. It is indispensable as a first tool.
There’s also a section on the forum to print out free targets. I think Michael uploaded like a few hundred printable pdf’s and other have some cool ones as well like the ten dimes challenge.
Again welcome to the forum and the hobby/sport. Stay sharp stay well sir!!
