Two postion scope mount? Adjustibility for ERL.

[SteveOak]

I am having a switch barrel rifle built. One barrel will be 6 BR AI, mostly for 300 and 600 yards, perhaps some fun at 1,000.

There will be two other barrels, 6.5 PRC and 7 PRC. These will be fired at 1,000 for finding scope settings and load verification with the ultimate goal of shooting 1 mile.

I'm looking for a scope mount that will give me enough elevation to go from a 300 yard 6 BR AI setting to a 1 mile 6.5 & 7 PRC setting.

Adjustable would probably be ok if it is solid and repeatable. A mount with two fixed positions might be better.

Is there such a thing?

I have not run the trajectories to get an idea how much come up I would need, just looking for possibilities at this time.

What scope you plan on using?
Available elevation is a huge factor for what your asking.
I run 6BRA, 7 saum and 338 edge on the same action, I have a scope with 100MOA available elevation and with 45moa rail I can cet a nice 100 yard zero with all and enough elevation to get to 2k with my 7mm and 2.5k with my 338 and was enough to get a mile with my 260.

30 moa mount might be enough for a mile with your 6.5.

A March-X High Master 10X-60X56M, 60 MOA

That’s a pretty limited elevation range
30 moa rail or mount is probably the max you would run and get a reasonable zero distance.

Guessing you’ll need 60ish moa elevation to hit a mile.

 

[SteveOak]

60 more?

I have a 20 MOA Pic rail now.

60 more?

I have a 20 MOA Pic rail now.

With a 20 moa rail and approximately 60 total travel you’re going to get 40-50ish useable

I had that issue with my 260.

Here’s another option for more elevation and they’ve made big progress last decade with prisms

NF also makes them.

ELR and low useable elevation scopes make things difficult.

Something like this is probably your best option with that scope.

The action is a LB/RP/LE BAT M. The locking levers might interfere with the bolt or at least with my hand when I actuate the bolt.

 

[SteveOak]

Just saw that you can get it with nut adjustment instead of levers.

My 338 Lapua improved with 285 ELDM at 3000fps needs roughly 68 minutes at 2K at 1000 ft elevation. I have a Field & Cave 50 MOA base that mounts to my 20 MOA rail. Perfect for an ELR set up out to around 2K. If I'm in 6000-8000 ft elevation in Wyoming, I can get additional range and it drops my necessary minutes to around 55 minutes of elevation. I like using my rifle for 500-1000 and I can do that with this 70 minute base.

Option B would be the Ivey system. I saw several of them at the Ko2M a few years back. They allow you to center the crosshairs and shoot out to the 2 miles at the range under competition conditions.

JMHO,
