I am trying to persuade myself into getting a double rifle or over under rifle . something big bore 45-70 etc for hog hunting. things hit another gear when you fire off a round at them and get out of sight quick. liking the idea of a very fast follow up shot. I know their is better choices for rifles out there. but I've been wanting a double rifle or over under rifle for a long time. and i am just not crazy about anything automatic.

My question is. BECAUSE of 2 barrels how do you zero one of these guns in with a scope? do you zero one barrel in and hope the other one is hits close? I've never seen 2 guns shoot the same, even if they are same brand , usin same bullet , etc. so how are 2 barrels going to shoot the same . ? i am just a little confused on it all. any help would be apreciated. I've seen some very good deals on over under/ side by side rifles lately. come with factory scope mounts etc. and any help , will help me make up my mind.

A good (expensive) double gun has the barrels regulated to hit the same point at a certain distance. However, a cheaper one might not be as accurate or well made and there's a good chance you'll end up dealing with two different points of impact.

go to the range, shoot for dead center look at where the firs shot hits then the second. duck tape the holes and see if they hit at the near same point. theres your POI

on this i was thinking of a baikal double or a rem spartan , something along that nature ? would these be considered junk guns then? would i have major issues trying to regulate the 2 barrels to shoot the same point of impact? i love the idea of a double rifle but i can't see myself paying as much for my rifle as i would my home lol

The regulating is done when the gun is being made and AFAIK can't be done after it's been finished. I have no idea how well either of those are made, but well-regulated double guns (both rifles and shotguns) are frequently those made on a piece by piece basis by hand. I've seen several fancy British double rifles sell for upwards of $15k. But hey, if the guns you're looking at aren't expensive, go for it. The worst that could happen is you end up with a steep learning curve for aiming it... The best that could happen, you end up with an inexpensive gun that shoots just as well as one that people sell their homes for. Either way, you end up with a new gun, and a pretty stylish one at that. :D

I had a Baikal SXS 30.06. Shot well for me without any tinkering using M2 ball. Guy I traded it to get 3" groups from it consisiting of 3 shots from each barrel at 100yds using Remmy 180gr Core-lokt. The rifle was rough, not like a fine English/French/German double, but very presentable. Triggers were rough and action had a tendency to want to close a touch, just enough to be a PITA when loading/unloading. The Baikals were hit or miss with regulation. Some, like mine, shot very well and others drove the owners mad enough to sell.

The next step up price wise is the 512 FinnClassic (Valmet 412). Double Gun HQ imports them in 9.3x74R (nearly 375H&H level) for $2250. IIRC they also sell the double trigger units. The 512 offers adjustable regulation for your chosen load. Scope mounts and extra barrels are also available.

Next is the controversial Sabatti 92 Basic at $3K. Non-adjustable regulation like a tradional double. The looks of a traditional DR. There has however been regualtion issues. Some rifles had the muzzle crowns ground to adjust regulation (Bubba the gunsmith) and some do not shoot anything like the supplied regulation target even with the listed regulation load.

Next is Verney-Carron and Chapius available from Kebco LLC. Traditional and both have good reputations.

Good luck.

This isn't true! A "properly" regulated DR will be regulated to shoot at any given distance with the rounds apart the distance the bbls are apart at the muzzle.

For instance, if the bbls are 1.5" apart at the muzzle, that distance should be maintained at all distances.

To the OP: If you want a DR that will be a hog killing fool and shoot VERY well, then buy a Valmet 412 chambered for 9.3x74R

Sorry if I was incorrect on the topic of double rifles, my mistake. However, I know this is a fact with respect to side-by-side shotguns.

Holland & Holland put out a nice double rifle. They even have an office in New York where you can go to get fitted for your rifle. The barrels are regulated to the folding sights out to 200 yards. You can even fit a scope. Prices start at $140,000, but if you want engraving that will cost a little more.:D

People shooting double rifles aren't hunting ground squirrels at 400 yards! Accuracy of 3" at 100 yards is plenty good enough when you're shooting huge African animals at 50 yards. That said, the better side-by-side and O/U rifle barrels should shoot within 2" of each other at 100 yards, but group size of each barrel, fired with iron sights, may only be 3".

Does fine accuracy really matter? If it does, get a bolt-action with a scope and pivot mount to use the iron sights if/when you need them. I'd probably take a double rifle for dangerous game at close range every time.

When you go to the DR forums, you will find more than a few that have taken big game with their DR's at longer ranges. A "properly regulated" DR will take game at longer ranges, no problem at all. It's really more about "can the shooter do it" than it is about is the DR able to do it.

My DR is regulated properly, and longer shots are no problem at all.

Even a poorly regulated DR can be used for long shots, just sight in one bbl., and use that bbl. for longer shots.

As for H&H regulation, i repeat: "properly regulated" means the bullets will be apart at ALL ranges the same amount that they are apart at the muzzle.

I have a .30-06 O/U, a Rizzini 90L. It shoots 180 grain bullets at 2700 fps+/- better than any other load that I have tried. It came with a rear sight that is drift adjustable for windage.
At 50 yards, the two barrels put the two shots touching. I have not been able to do that at 100 yards - but I haven't tried very hard either; two inches is more the norm for me. I have never had cause to shoot farther that that.
Zeroing...the bottom barrel on this gun fires first. That is the barrel that gets zeroed.
