First the barrels are moved in relation to each other to get them printing an acceptable group and then the sights are moved to move the group to POA.

Because I wanted to build a 12-bore rifle and I didn't want it to weigh twenty pounds.

A .45-70 with the barrel contours of a 12 gauge gun would be very heavy and if the rifle barrel contours were small enough to effect a reasonable weight the rifle would suffer aesthetically.

Besides, the .45-70 conversion is the go-to conversion so I didn't want to go down that path.

Even though the .45-70 is a low pressure cartridge by rifle standards, most if not all factory loads far exceed 12 ga chamber pressures.

The forend latch is the standard Sterlingworth snap-on type.
I decided to combine the forend iron screw escutcheon with a metal forend tip. It's machined and filed out of a piece of 1020.

The barrel length is 24 inches, weight is 8lbs, 14 oz and the balance point is at the edge of the action knuckle (just ahead of the hinge).

The gun is regulated with Lightfield Hybred (their spelling) 546 grain, discarding-sabot slugs.

It's an ejector gun and the engraving will be minimal. I don't want someone else's work to get top billing.

Thanks for the reply, Dewey. I assume the owner will use it mostly on whitetails. What do you figure it to fairly be, a 75 yd. gun? Again, it ought to be dog nuts on hogs in the thick stuff.

I really like peeps on a gun like this. I usually screw out the aperture and just look through the "housing" when the light gets low, or if a snap shot is imminent. Surprising how accurate you can still shoot with a great big aperture. Your eye just naturally centers the front sight in the aperture regardless of how big or small it is.

Dewey, like Stan said, thanks for indulging us here, a couple more questions-what are the stock dimensions, annnnd, would it be rude to ask, among friends, what the final ticket might run, out the door?

The peep sight is quite effective. I agree that a large aperture can be as fast to acquire as an express sight.
It's just the thing for older eyes.
I'm sure that the gun and ammunition combination is capable out to 100 yards but I'm just as sure that I personally am not.
75 yards would be my limit.

The stock dimensions are:
1,7/16" Drop @ Comb
2,1/16" Drop @ Heel
13,1/2" Pull to Sole

I'm afraid that I can not divulge the price.

Thank you everyone for the compliments. They are sincerely appreciated.

Here are some construction photos.

The front sight,









Swivel stud,

First & foremost let me say You should definitely have built what you wanted. As a retired machinist I truly admire the work you have done here.
I do however want to make one comment about the chamber pressure of the 12ga vs the .45-70. Chamber pressure is of course given in PSI or pounds per square inch. The chamber walls of the .45-70 would certainly have been thick enough to handle the increased pressure. As to the thrust on the action the 12ga has about 2� times the area of the .45-70 at its head. Therefore a the thrust from a 10K load in 12ga would be about equaled by a 25k load in the .45-70.
Ideally though to build a .45-70 I would want to drop to a 20ga frame to get the narrower & shorter standing breech. I think you made the right choice for the 12ga frame.
