Assume I have a .375 S/S double. I put a low mag scope on it. I am sure I have read that you only sight the scope in for one barrel or the other but I can't for the life of me work out why. Wouldn't it be better to shoot both barrels (I assume you would get lets say 2" at 100 yds and sight the scope to the middle of the group.

Mike,
Yes, the idea is to end up with your scoped double shooting both barrel groups to the scope.
This may or may not require a new load to be worked up for the rifle once the scope is mounted.
About the only time you would sight the scope to just one barrel is if you could not get a load to shoot both barrels to regulation after the scope had been fitted.
In that case re-regulation is another option.

Mike,
Why a scope on a double rifle? If you are looking for accuracy , put it on a bolt action rifle!

Grandveneur, Regulated properly, there is no reason a double rifle cannot produce as good accuracy as any hunting bolt rifle of the same chambering! I have seven double rifles, and I don't think you want to stand at 300 yds and hope I can't hit you with all but one of them. The one that is limited is a Muzzleloader 58 cal double, that simply doesn't have the range capability, but look out with the 9.3X74R, or the 8X57JR double!


Mike Bailey, what you want to do is mount the scope as low as possible, and choose the scope that is as light as you can find. This will effect the recoil flip far less, and will not, in my experience, usually blow your regulation. You are correct! Find the center of each barrel's individual group, and zreo your scope exactly half way between the two centers, and go hunting!

.......................Good hunting!

That's right, there is no reason! But with my Double 577NE, with open sight, i shoot at 200 yards too!

That is true of most double rifles worth owning, being shot by those who know their rifle! However, long range bullet placement is not the only reason to have a scope on any rifle! They gather better light, than the naked human eye, when the light starts to fail, or before it improves in morning. In addtion to that, it lets one see the tiny twiggs between you and your target, so you don't deflect a bullet cuaseing a wounded animal to deal with. It lets you slip a bullet through a small clearing in the bush, to collect the heart or brain when nothing else is visable.

With a double rifle, the role of the scope sight is reverse to it's use on a bolt rifle. On the double rifle the scope is the secondary sight, used for special ourposes, so is only mounted in QD rings, and bases, to be attached only when needed. On the bolt rifle the reverse is the case, with the scope being the primary sighting system, with the irons as a back-up, in case the scope goes south! Both sceenarios are valid!

I agree, that I wouldn't mount a scope on a 500NE, or 577NE double rifle. Eventhough the pros for the scope, under some conditions, would be just as valid on those as on the smaller rifles. Just not enough to justify the bother to install. On a 9.3X74R, 375HH, 450/400NE,or the verious .450s they are a fine, and useful addtion. Then you have people who simply cannot see iron sights, and have no choice!

Obviously yes.


Someone said if it doesn't regulate with both barrels with a scope attached, it needs to be re-regulated. I disagree. If it regulates just fine with open sights, but placing on a scope changes that, why mess up the open sight regulation? Use it as a single shot with the scope when needed, otherwise use it open sighted as it is meant to be used.

As an illustration. I am not confident shooting my .450 at longer ranges. However if I could shoot it at say 250 metres as a scope sighted single shot it makes it a lot more versatile. BTW it is NOT fitted for scope mounts anyway.

I think a scope and open sighted lighter weight double which regulates for both, in .375 and/or .400 is definitely an extremely versatile rifle and well worth having.
