    Posted: November/17/2016 at 02:39
I've got a Vortex Razor HD 5-20x50 that I want to mount to my Remy 700 5r in 308.
This is a heavy scope so i'm thinking about mounting it to a rail.
I'll be shooting mostly at under 500 yards but occasionally 1000 yards.
I'm thing of installing a 20 moa rail but worry about close in shooting, 50 yards, etc.
Do you think I should go 20 or 0 moa?

If you do not find your self shooting beyond 600 yards frequently I recommend that you use the zero MOA.
This will allow you to zero the rifle at 100 yards and still have plenty of upward travel internally to shoot longer distances.

Going with the 20 MOA, may augment a true 100 zero to a farther distance.

That scope has a lot of internal adjustment so even out to 1000 yards with no slope base I think you would be fine.  I have a 20 moa on my precision rifle and a SS 5-20x.  I can zero easily at 100 yards and can dial out to 1400ish. 

If you choose to get a flat base, then I would consider something like Talley one piece ring mounts.  Would clean up your loading port and stuff.  Really no need for a picatinny base if you are going 0 moa.  I often consider doing that with my precision rifle as well.

I've ran a 20 MOA rail with a cornucopia of scopes and have never not been able to set a 100 zero.

Excellent commentary before, but I particularly like what ST said about the Talley LW's. If you're going to go with a zero cant rail and don't have a DM system, I too would go with the Talleys....and I have.

At this juncture, the only thing a zero rail gives you is more fore and aft when setting your scope up.

Wow, that is crazy.  I have always been able to get a 100 yard zero.  I even ran a 30 moa base on my old precision rifle and was able to get a 100 yard zero with 5 different scopes.  Two IORs, and three different SWFA SS scopes.

That was a great thought but I checked and Talley doesn't make a one piece LW ring in 35mm.

Maybe I should call SWFA and ask.
I have a Remington 700 5r mil spec Gen II rifle and a Vortex HD 5-20x50 scope with 35mm tube.
I'd like to use a set of Seekins 35mm rings.
Now I have to decide on base. Do I go rail and if so should I go 0 or 20 moa and if I decide to go 0 moa do you think I should use a two piece base set instead and if so, which set is best with these rings.

Ah hell...I didn't know it had a 35mm tube. Seekins are TOP SHELF rings. 

On a canted vs non canted rail. 
Get a 20 MOA rail and call it a day. THIS scope has plenty of up, but the next one may not have the up to get you to 1000 yds. Get it, bed it, and start shooting. IMO 

I run a stock pack on mine to give me a little bit of rise in the cheek weld. I ran Seekin low rings on a Badger 20 MOA rail and it worked perfectly.

Thanks for the information cheaptrick. If I run a 20 moa rail with this scope, will I be able to sight her in at 100 yards without a problem?

Thanks peddler!
One more question, I'm now thinking of installing aluminum rings to keep weight manageable, this is a heavy rifle and heavy scope. Do you guys think an aluminum 1913 rail would be strong enough to hold that heavy scope or should I go steel and can I mix aluminum rings and a steel base or should I go all aluminum or all steel?
Thanks,
Sam

Personally, I would keep the bases and rings one material. That bring said, alminum is going to be plenty tough enough for a 308. Seekins makes really good rails as well.

One nice thing about aluminum is your rings and base wont rust. I have had steel badger, TPS, and IOR all rust on me. My seekins and talley stuff never rusts.

I personally would also go with aluminum for weight reduction. Go with Seekins and you'll be fine.

The scope is a Vortex HD 5-20×50 with a 35mm tube. It will be mounted on a Remington 700 5r mil spec Gen II in 308, the barrel is a bit heavy.
If I go with a Seekins 20 moa rail, what size Seekins rings do you think will work, low, med or high?
Thanks

Thanks cheaptrick, that's good news. I was afraid the 35mm tube and 50mm bell would have to be mounted higher.
How about screws for the rail, do I need 8's for this 32oz scope or will 6's do?

I have medium highs on my precision rifle with a SS5-20x50. But its only a 30mm tube. I had mediums on it first and i couldn't put scope caps on it. It has an m24 profile barrel.

Give them a call to see if the low rings will work with a 35mm tube. I keep forgetting that's what you have. 
"Most" 30mm/50mm scopes will be OK with lows.
