New PS90 Owner (ranging questions)

Post by TheGunGeek » 14 Oct 2016, 19:31

Hello all,

I will be the owner of a new PS90 within the next couple weeks when my order comes in. I have a couple questions for those with experience. My setup will be the 16" barrel with a low profile mount, and a Trijicon RMR Adjustable LED 3.25 MOA for the sight. I will be using the SS198LF round.

1. Given my setup & ammo above, what would be a good distance for the initial sight in?
2. Does the SS198LF have a flat trajectory out to 200 yards from the PS90? If not at what point does it start to drop.

Thank you in advance for any help. Where I live the longest rifle range distance is 200 yards, so the PS90 should be a good fit.

At 200 yards you will have a real hard time seeing the holes in the paper from the 5.7x28. Most people set their PS90's up to be more a personal defense weapon (what it was designed for), and most of them will use a 50 yard zero. Can it shoot 150-200? Sure, but the usefulness of this round is its velocity, and that drops with distance. Personally 90% of my shooting is at 25-50 yards, with occasional fun on steel at 100. I would not waste the $.50 a round poking holes in paper at longer distances with a PS90. I would not bother setting up a zero any further than 50 yards as it will make the gun less useful at the closer ranges where it shines so bright.

"200 yards Murder1" Hee, hee

Yes, you would have to be damn deliberate to get a good hit at 200 yards with a PS90, even with the 16" barrel version. And most courts would see "deliberation" as "pre-meditation".

This post is interesting B/C last week I sighted in my PS90 with its new Vortex SPARC II red dot to be 1" high at 50 yards so it would be very close to zero at 100 yards, my max effective range.
Amazingly my PS90 is nearly as accurate at 50 yards as my lever action Ruger 96/22 magnum with its fancy Green River octagonal barrel. Both are shooting 40 gr. polymer tipped bullets.

(My wife gets the PS90 for the Zombie Apocalypse and I get the AUG.)
