ramrod340Were or how to start with regulation (NO OPINION?)
Well since I had a EAA shotgun gathering dust and got a deal on 45-70 insert barrels I now have a poor boys double rifle.
Thanks to Nitro450 I have a couple loads that worked in his rifle.
This is my first playing with a DR (such as it is) so since regulation for the most part is a total unknown how would a newbie start. My 40 years of reloading single barrels isn't going to help me much except I do know how to load a case.
Help
As usual just my $.02

RustyTo begin with, it isn't about how fast your drive the bullets. It is about regulation. A chronograph is a must when trying to regulate a double. And a lot of patience. I presume these inserts have some kind of adjustment to them?

Rusty what the inserts have are a set of two different non-concentric bushing. Only difference between the bushing is the amount of offset. Have a Chrono so that isn't an issue.

JudgeGI used lazer boresighters to get the barrels aimed about 2" low and 2" left and right respectively at 25 yards. I used a vice to do this, turning and tighting the bushings as appropriate.
Not having Rusty's understanding of how the barrels "work" and how the gun recoils with a torqueing motion, at first, I had the lazers meeting at 50 yards. I yet have found where bullets so shot went. I think the right killed a cow in Kansas and the left a guy in Taiwan.
That first try being a disaster, I've forgotten who gave me the suggestion of where to "aim" the lazers (each barrel low and off set, but it worked. Well, kinda.
I had some 350 lead cast bullets that trundled along about 1250 f.p.s. and found, amazingly, first try, that they made a 3.5" circle at 50 yards, pretty much with the right elevation and windage.
The sights were so bad that I couldn't tell if the group size was because of my poor shooting, the 8 lb. triggers or the crude bead and rear leaf. The bullets sometimes crossed, but that may have been because I let the barrels get too hot.... and they will get hot!
I traded it, not because it wasn't a adequate hog gun in the bushes, but because a guy was convinced he could get better performance with hotter loads and better sights (and I only had $450 in the whole thing)... and he had a model 94 trapper I wanted. What his efforts yielded, I don't know.
I eventually bought another insert set and another Baikal double, but never tried to regulate it, selling it to someone here after installing the inserts.

That is almost twice what I'll have in this one.
I had picked up the shotgun at a show for $100 because the end of the stock had a huge chip missing. My wife was 5'4" so I cut the chip off. I picked up a new stock for the rifle experiment for $49 online and a member here had a used set of inserts he was willing to part with. Then he also sold me a bunch of reloading material.
Back to the topic. H ad thought of doing a boresighting like you talked about using the bushing to try and set the barrels each a little low and to their respective sides. Then Use somethng like a 350 cast and increase the load until I got a decent group.

jimatcatjust grip it and rip it!!!!.....all kidding aside, without knowing where it DOES hit, it would be hard to offer constructive advise... that being said, there have been times when i used a boresight and still missed paper....
go big or go home ........

I'm not looking for advice on how to work out the last couple inches. But where to start.
My thoughts since they are inserts I had thought to start like Judge had. Bore sight the barrels to be low and to their own side of zero.
Then start with???? I had thought a middle of the road load with some 350gr cast. Something in the 16-18,000 psi range.
Then work the inserts to get them closer. Finally start working with the load.
Is this left field? Is there a better way to start?? I'm at the bottom of a learning curve.

mouse93As jimatcat said - grab some and fire away - ~20yds would be my start and see what happens...
