Long range verification

[sqearl]

Hey guys. I just received my suppressor, spun it onto my 300 prc. Dialed it in dead nuts 100 yards. Then I stretched it out at 500 and 1000. That's where it was hitting high and right at both 500 and 1000. The high stuff I can verify and work in. The right I can't figure out. Any insight or advice

Spin drift.

Spin drift.

Especially at 1000. OP, did you account for this?

 

[sqearl]

Spin drift.

Even at 500? I didn't have any fly that far with just the muzzle break.

Especially at 1000. OP, did you account for this?

No I didn't. I guessed that with the suppressor it would shoot close to the muzzle break

You changed the Harmonic to the barrel with the suppressor.

So I figure you were dialed in before the suppressor.

Yes. Zeroed at 100. I spun the suppressor on and it hit high right. Then I zeroed with suppressor and so on like I mentioned

The suppressor increases muzzle velocity which may not change your impact much at 100yds but it will show up at further distances. This is why you are shooting high at 500 and beyond. You are shooting even higher and to the right because of spin drift. The twist of the barrel adds an angular velocity to the bullet as it travels down the barrel. Over time of flight this angular velocity causes the bullet to move high and right from a RH twist barrel.

Then you did have it dialed in out to 500 and 1000yds it was done already before the suppressor.
Forgive me if I have this mixed up.

It's a 1:8 twist. If this is the case. How do you figure the spin drift I've never really had to figure it

Dialed in with out suppressor. Now doing it with suppressor

As mentioned you will need to retune your load for the suppressor.

Also, how much right were you missing? There's a lot of variables at 500-1000 yards. A slight wind you may not feel at shooting position can easily push you off target. Also as mentioned spin drift has an effect at these ranges.

When I first got my supressor I had to put a few rounds on it like 20 or so seems like it gets dirty and settles in. I had a slight zero shift and velocity increase. So I do all my load development with the suppressor on. I can tell you shooting at distance If I take suppressor off and put my brake on the brake will shoot 3 mil high at 1400 yards compared to suppressor. I run the area 419 system
