20 MOA ? For Remmy SA

Gun is a Remmy SPS Tactical in .308. Scope will be Vortex Viper PST FFP 6-24x50. Yardage will be 100yds up to 1,000yds. Is a 20MOA mount required for the 1,000yds? If yes, what's the best bang for my buck (I don't need the best but don't want junk)? Thanks!

With that scope it's not required but I would go ahead and put a 10 MOA or 20 just to keep the elevation closer to center if that makes sense.
Talley or EGW are good and not priced to bad

Weather you need it will depend on bullet and velocity

If you are just putting together i would get a 20 moa just to be on the safe side. I would look at the larue bases.

I already have a DNZ 1 piece mount but would get a 20 MOA if it's truly needed.

What bullet and velocity than?

On my old 308 I could get to 1200 but would have to need to hold a couple of mils on the reticle

That scope has 65 MOA (so you would have half that to work with)of elevation so depending on bullet and barrel length you are on the borderline of reaching 1000 with a zero base.
My 308 load takes 34 MOA to 1000 give or take and if you chose the mil version although your scope could have Holy water applied by Fireman it would still be borderline as it has 19 mil so half that is 9.5 and a 308 is about 10 mil to 1000 agin depending on variables
Oh and I have both MOA and Mil on my .308's and I just ran Shooter with my data with today's condtions to check the numbers

A-Max 168gr @ ~2,650.

So that should be 39-40 moa drop according to my calc. So without a base you will have to do a reticle holdover

That bullet won't make it to 1000, it'll go sub-sonic around 850-900, then start to yaw. Switch over to a 178 A-max and it'll get there.

The scope is built to be mounted on a 20 MOA base, so you might as well get one. When zeroed at 100 your turret should be on the first rev line, giving you several revs of up-travel.

EGW aluminum one piece 20 MOA pic rail for about $60 through SWFA.com or MidwayUSA.com. They've screwed right on every Rem 700, Savage, Tikka, ect I have installed them on.

Is the 178gr not too heavy for the 20" bbl? Btw, I'm still trying to get Buddy to go shoot. Thanks!

Both my .308's have 20 inch barrels and with the 175gr Sierra Tipped they get to a 1000 with the above mentioned dial ups no problem at all.

Thanks!

Not sure how good they are but larue bases are only $75

You could use the phenomenon that is the 155 gr. Lapua Scenar. Enough BC to get to 1000, and gains a ton of muzzle velocity over the 175, 178 gr. offerings.

I would probably go that route if I had a long 28-30 inch barrel myself.

I don't get it. If you have a 24"+ barrel, you can run the 178 gr @ 2700 fps MV.

The beauty of the 155 Scenar is it has a high BC for its' weight and gives the 22"- barrel some velocity back.

I have loaded both 155 and 175 and I do get slightly less drop but wind drift is actually slightly less with the 175 and they group better in my gun? Now if I went from my 20 inch barrel to a 30 inch and could get to 3000 plus fps then the 155's might get the nod.

My way of thinking is opposite. The longer the barrel I have the heavier and higher BC bullet I am going to run. Sure a short barrel will stabilize a long bullet and it will push it slower. There comes a balance of BC and MV, so the short .308 would get a 155, the 24"+ would get a 178, the short 6.5 Creedmoor would get a 130 gr instead of a 140 gr out of a 24" barrel.

In my guns and the speeds I get they are a wash really. I can run 175 at 2670 or 155 at 2920 and they are about equal in drift. So I chose the more accurate.

I would too. Inside 600 yards each one probably does a good job for you. It's really a beautiful thing to have a 308 that will shoot very well on a 155, and a 175-178.

This has always been my train of thought. On the flip side, it'd seem that 155 would get pushed around more by wind when reaching way out there. I guess if the velocity is still high enough, it doesn't?

Muzzle Velocity AND ballistic coefficient is what matters at distance. Why I called the 155 scenar a phenomenon. A loss of 20 gr of weight, and therefore length, and yet it still maintains a BC of .460. Yet can be pushed significantly faster than the 168 gr. SMK with almost the same BC.

I'd have to run numbers to see which will be better. A 178 gr A-max with an MV of 2620 fps or a 155 Scenar. I would need to find out what velocities guys are getting. I never tried the Scenar when I was shooting .308

The speeds I mentioned above are from two 20 inch barreled .308's and I run the exact load in both. I have used both rifles in our local 1000 yard match that only allows .308.
One rifle shot the 155 very well but the other only so-so. Both shoot the 175 Sierra great and since wind drift at the respective velocity is less than an inch(175 is better) difference.
I am basing my statement that I might go 155 if I had a long barrel is that Palma shooters tend to do so but they are running 30 inch plus barrel length.
I could see the 155 gaining an advantage at nearly 3000 fps against a 2650 175.

Good info.

Right there, I would put a 178gr in the 30" barrel. Keep the .505 BC and get it going 2800 fps. But I'm kind of a BC hound.

What about this one?

Have that exact one on my 5R. No complaints and I like that it is one piece. No lapping necessary ( if you've ever been into that)

I actually have the same one already w/out the 20MOA. I think it's a solid product that's priced nicely.
