At 150+, you will want a scope. A scoped double will cost more although for the one barrel sighted in, should be nearly as accurate to 150. The second barrel will have to be re-regulated for that distance, and I am not aware that any mfg is doing that, unless you contact Merkel to see if their gunsmith can regulate on of their 141s with the adjustable barrel feature for that range. (They offer it in 30-06 and in 9.3X74R, which should work for most Western game at 150. They also offer a scope mount for a reasonable price.)

Now, go ahead guys, give me some grief on this, but remember, I love DRs too, but for what he is thinking about, a bolt will work better for less.

Just my opinion. Dave

No grief, but only a friendly correction!

The rifle should be regulated Physicly for the round you intend useing, in the normal manner with is:

With your iron sights on the point of aim, the right barrel should hit, slightly on the right of point of aim, and the left barrel printing, slightly on the left of point of aim, regardless of distance. The center of each of these two individual barrel groups, should be close enough to the center of the other barrel's group, to form a workable composit group of both barrels with the POA in the center of the composit group. This is proper regulation, and the barrels are shooting paralell.

NOW!, the scope is mounted in the QD rings & bases, Now clamp the barrel set in a vice, with the iron sights on the POA in the center of the composit group. While the barrels are being held, look through the scope and adjust the scope to cross hair exactly on the point of aim. Now replace the barrels on the rifle, and adjust the scope to the DISTANCE you want the scope to zero. In this case 150 yds. The windage is already set, but if you limit your iron sight shooting to 100 yds, and you want the scope zeroed at 150 yds, then set the scope high enough it will print on POA at 150 yds! Not magic, just different!

Ideally the distance between groups should be the distance between the centerline of the barrels.

...at the breech, rather than at the muzzles, but we're splitting hairs here. The muzzles are closer together than the breech, but they will recoil apart slightly before the projectile exits the muzzle, to about the width between centres at the breech.

Clear as mud....

I'm interested to know where this belief comes from.
Is it chisled in stone someplace?

Allen, it comes from simply being fact! However, what I think confuses even those who are well up on double rifles, is the misconception that saying the shots from each barrel do not cross at any distance! This "IS" wrong. What should be said if the "CENTER" of each barrel's group do not cross at any distance! A group fired from any barrel will get larger as it flies down range. If there are two barrels side by side, as the two groups get larger the shots on the right side of the left group will certainly cross over into the group from the right barrel and vice-versa. this only means the composite group of both barrels gets larger as it flies down range, but the center of each barrel's groups remains on it's own side of the POA!

Even if a single barrel fires four shots, all four will not het in one hole, and if that barrel is fireing a MOA at 100 yds, it will be 2 MOA at two hundred yrds, but the center of the group will stay true to aim! This is why the mistaken idea that multiple flip-up sights on a double rifle are simply there for decoration, and they are not, if the rifle is loaded properly to the regulation of the rifle it wwill shoot to those sights at the range they are set for, and you will notice all the centers of those sight baldes are in line with each other!

Grizzly- it took 2 9.3's to secure that coyote? I guess it's powerful enough if you hit them right, eh? ;-)

---

Daryl, I was there, and the coyote was quartering toward Tony chaseing some deer, the first shot hit the coyote just behind the left shoulder going back into the gut, actually gutting the coyote, causeing him to go down, but he was trying to get back up, and started to go in circles, when the second barrel hit him square takeing him out for the count! This was filmed, by another hunter, but I don't have a copy of the film, maybe Tony does!

We are all being anal in this.

It is probably impossible to have a group from each barrel stay parallel to 300 or 500 yards. As was just pointed out each barrel group expands also thus overlapping the other barrel group. The centres may stay the same but what the hay.

I'm perfectly content with this load.



At 140m these bullets would be reversed and at 210m the spread would be crossed but still within 1 inch. Isn't that really good enough?

---

Mickey is correct, the parameters set fourth are the "IDEAL" that one aspires to achieve! IMO, one can never achieve regulation to that degree, but one must get as close as he can to the IDEAL, to get the best from his double, especially for down range use! The group posted above is as close as on can get without crossing, and certainly is GOOD ENOUGH! Nothing is perfect, but that is about as close to being perfect as one can expect.

The perfect individual barrel group is the best group you can get from your tightest shooting barrel, and as long as it's center is on it's own side of POA, but close enough to form a composite group with the other barrel's group center on "it's" own side of the POA, at 50 yds a very good composite group is a 2" egg shaped group with the center of each group on each side of POA, the POA being half way between the centers of two barrel groups. With a composit group like this, the rifle will shoot to down range sights as well as can be expected, and quite acceptable for hunting purposes. The fool deer, or elk, that thinks I can't hit him with any double rifle I own, at 200 yds is in trouble! As I said, nothing is perfect, but that doesn't mean you should accept a load that follows the idea a double rifle is only accurate at 50 yds or under, which seems to be the opinion of most gun writers!
