Hey guys need some help. I've just gotten my new suppressor spun it onto my Christensen 300prc. I've dialed it in dead nuts at 100 yd. Then I shoot it at 500 yd. High and right. I try at 1000, high and right. Now the elevation I can dial in. The right has me baffled especially when it is zero at 100. Does anyone have any insight or advice I could use. Thank you in advance

Wind?

Like was pointed out in your other thread - likely spin drift.

Wind, maybe some spin drift and shooter error that is magnified at that distance? Only guessing at this point.

How much high and right are we talking? How did you obtain the muzzle velocity you are plugging into your ballistics calculator? At 500yds you will start to see some significant spin drift, and at 1000yds it drifts quite a bit.

As I mentioned in your other thread. The suppressor will increase your muzzle velocity which is throwing your dope off. You need to measure MV with the suppressor on. Or you could go the long way around and confirm dope at range and then use a MV correction to match the dope in your calculator.

As others have pointed out, its likely Spin Drift or wind
Download Eagle ballistics app it will correct your bc and compensate your spin and Coriolis

I'll throw a wrench in here and suggest maybe a little rifle cant into the mix for the right.

If you're having trouble getting readings with your suppressor and your chrono set the chrono at the end of the suppressor and maybe 8-10" to the side. I called the guys there as I was having trouble getting readings with the can, and it totally solved my problem. All my guns shoot different with a suppressor, velo, poi, recoil, and I'm sure barrel harmonics are vastly different. I really like levels on my scopes, cant is a real deal with me. I try to have two levels on the rifles I hunt with at long range just in case one of them is off, I'll know I have a problem.
