Rifle Scopes Scope for subsonic 300blk

[G3A3A1]

I am in the process of picking up a SPR300, I want to push it out to 500 meters. At that range it still has more kinetic energy than .45ACP at the muzzle. Anyway, I will need around 70MOA of adjustment at 500, so I am also assuming I will be needing to pickup a 20MOA base as well. The main thing I want from the scope is a zero stop, as well as the ability to dial back down to 2 or 2.5 magnification. Since I am shooting relatively short distances I don't need 24 or 40 magnification something like 10x would be plenty. However it seems that for a zero stop most scopes run higher magnification. So what would be a good choice for this rifle given the somewhat unique situation?

A 1-4 or 1-6 power would be ideal for that platform given its range and energy.
Good short range performance with the right load and bullet but saying it has more energy than a 45acpat 500 yards doesn't mean much if it is way below the opening velocity thresh hold for the bullet being used.

i have a NF 2.5-10x24 on my Q HB SD in 300, and a NF ATACR 1-8 on my Q minifix 300 SBR. Awesome.

I have a 1x4 trijicon acog on my blackout......the close eye relief is a thing......but the optic has both bdcs for super AND subsonic loads on one reticle......

Although they don't even think of going out to 500 on the subsonic side hahahahaha......

The grendle is what you seek.......I put a 1x4 acog on the blackout as a home defense gun.....

I put a 3x15 on the grendle as a 0-600 yard pistol

You might get out there with the blackout.......
You will get out there with a grendle.....

I can still buy grendle ammo.....haven't seen blackout in months lol....

Just my 2

If it where me I'd put a razor 1x10 or a acog ...and a 45 degree offset redot.....

.I went with the acog because its always on ,its lite ,and with a 45 degree offset redot its a very fast combo from 0-as far as you can hit with a 4 power....the acog has great glass for the price as well

Oh boy, lol.

Oh boy, lol.

That was my same reaction. Don't subs basically run out of steam past 150? It would be a lot more plausible to simply realize you're going to need to use supers past 200, and then plan your scope use accordingly; dealing with multiple zeros on a exposed locking turret isn't that hard anymore if you keep the paperwork straight. (In this case, I'd have your zero on your sub load, and then know the offset to the zero for your super load, and program your ballistic calculator to deal with the offset).

Hahahaha, on my acog the 300 yard supersonic zero
Lines up with the 50 YARD SUB sonic zero....

This is why I mentioned a grendle.

I would heed XLR308 advice above in post #2, most projectiles used for subsonic will not effectively open/expand at the slow speeds. Look at Lehigh Defense for some options there. 500 yards is pushing it for subsonic for sure, there are no BDC style reticles that would take a subsonic out to 500 yards so I'd suggest a good mil reticle. You didn't mention a budget so I'd say the new Vortex Gen III 1-10 would be very nice, but if you're looking for something on the cheap then maybe a 2-10 ish scope with a good mil reticle will be best.
