Adjusting the sights of a double can be time consuming but, once completed, the results are worth the effort.


Four shot group (2L, 2R) from the Acme "Lingua Ina Maxillam" 12 bore.
This was off the shooting sticks while prone:




The 740gr bullets were hitting a bit high and a bit left.
So, using a rasp, I ground a little off the top and the right side of the bead.
Then I fired these eight shots, four from each barrel (4L, 4R).



I'm happy with the elevation because my Acme rifle has to hit an inch high at 100yds to be zeroed for 200 yards.
But, I accidentally took a little too much off the right side of the bead.
So, I went back and took a little off the left side of the bead to center things up.
Now I need to buy some fluorescent green paint.
The front bead has become a thin, flat-sided wafer too thin to see.
Once I get the front blade painted I'll be able to shoot another group to post and prove that everything is now perfect.

Not bad but you could tighten it up a bit by adjusting your cheek to ground weld and holding the left corner of your lip up while shooting.

I think you need to give it a good clean with jb paste.

then fire thirty random shots on the target so we can't see your real group.

Nice shooting btw. Cheers Chris

Excellent!
I can get a group that small by doing one of two things:
tape the target to the muzzle, or
shoot one shot from my 4-bore.
Jolly good show!

WOW! Pretty work!

That shows what can be done with a rifle when you use the proper reloading press, you clearly are not using one of the sometimes troublesome metric presses. Well done!

I never had the metric problem but I did have trouble till I found out about the left and right rifling. The right barrel of my "Lingua Ina Maxillam" is rifled clockwise and the left barrel is rifled counter-clockwise. As everyone knows that spins the bullets from the right barrel to the right and bullets from the left barrel to the left. I kept getting very erratic results and I felt really stupid until I figured that out. Silly me, I was loading both barrels with the SAME BULLETS! Now, I am always sure to shoot the right-handed bullets in the right barrel and the left-handed bullets in the left barrel.

Do you have time to drop by and assist me in regulating my double. It seems you have the method down pat. That's what they said about Richard Nixon you know.

The gun came with the rear sight off center by two inches so I had to knock that back. It was making me shoot a foot right at 10 yards. That would have put me 6 inches right at 25 yards and 1 inch left at 50 yards. Can't have that. My "Lingua Ina Maxillam" is the best rifle ever built.

It's probably a good thing that you didn't have to replace the front sight insert as that may have become an insurmountable obstacle. Do you plan on MIG welding the rear sight in place or will you just use something like JB weld to do the job?

PS Do you know if Cabela's sells prone shooting sticks?

Definitely the best double rifle ever built, so far! Amazing what one can do using a bastard file applied to the front sight when you really KNOW what you're doing instead of just walking with a lantern in the dark like others on this forum.

Agreed. It is finally good to hear from someone who KNOWS what I am talking about instead of all those posers and wannabe shooters who post on this forum. Some people think they are experts just because they have decades of hunting, shooting, reloading, and gunsmithing experience. They don't know nothin'. I learned more in one weekend with my Acme double rifle then the total accumulation of all their knowledge. Who do those dummys think they are!
