Today I got to shoot my double from the shoulder for the first time, and the sound and kick was there thats for sure.

On 25meters she crossed 15cm so i turned my homemade regulating bushings to use half of their capacity (0,3mm) and now they "only cross 12cm.
So my concern that shotgun barrels are to crossed seems right, but the barrels are floating so this could be a factor.
Now i have heated the front of the barrels and spread them 1mm, messuring with a couple of boresighters the barrels now cross about 6cm in 20m (before 18cm). Tomorrow i will give it a try ones more to see if they are about right, and if i will test it in a 100m range.

Great looking job. Are you keeping a rough record of your time? Some fine looking machines as well.

Thanks, with my mistakes and all i think 150-200 hours. But now when the barrels are moved the blue is ruined, so it would have been faster and better if i made a monoblock.
But hey, i made it to learn and i did so i cant complain.

Andreas,

We tried the ecentric cams once with a sauer and had the identical results as you. We ended up locking the cams back to center and then spreading the bbls. Fortunately, the spread wasn't so great and we were able to use the orgional rib. It can be a long process just don't get discouraged. :^)

Were was you a month ago, nowing this could have spared me a lot of work. But to be honest i would have done it anyway, it just was as a damn good way to regulate.

But i invented a whole new way to do the job, i have applied for a patent so dont tell anyone.



Dont mind the corrosion in the barrels its cleaned out now.

I think 20mm is allready very good, but you have to live with the result. Do you intend to do a lot of long range shooting with it?

Andreas,
I would like to ad a little of my expereince.
A couple of points:
1- Shoot from off hand or at leat not resting the rifle directly. I found that what works for me is resting the back of my forward hand on an horizontal post as a rest.
2- Shoot at two targets, one for each barrel, so you know where each barret hit from aiming point.
3- You should try at least 3 right-left to know where it shots.

You need to know exactly how the rifle shot from a free recoiling position as when hunting.

Hope this helps.
Martin

I shoot from sticks only resting the rifle in my hands and on two targets but as the importer of the powder i shoosed are out of stock im short of round so i only shhot one from each barrel.
But when they get closer on the target i shoot two from each barrel. And then some for fun.

Andreas,

i hate to say anythng as I usually end up stcking my foot in my mouth but here goes. We would shoot four and six shot groups and determine the average then make an adjustment. I would start with clean dry bbls and try to shoot the shots at a steady pace. Not rushng but not didlng around either. Dad would mark the shots with the spottng scope and mark them on a target at the bench then back at the shop we would measure the shots on the actual target. This last gun would always shoot one hole wth the right bbl. but the left group would always be larger. Still, it took us forever. :^)

As above but i was using my father (standing by the target) but started to question his math capability. But after two round from each barrel she starts to warm up so further shots wont do anything.
