maybe one in Elios Gunshop, Dunedin, ph 03 4555 783, hardly used, but why in .30'06?  Double rifles were built for rimmed cartridges!  Rimless cartridges work in (and were designed for bolt [magazine] rifles).

Using a rimless case in a break action rifle is not as "nice" as using a rimmed case, I modified a 12 gauge shotgun to 303 British and it was about right, the just about bit was the action not was configured ideally for the case size.
The Baikal Artemide Double is based on just the right sized action and would be ideal chambered for the big Russian 30 cal. rimmed case.

they come in .45/70......my "one day when funds are spare" dream rifle for bush hunting.
the rimmed bit wont matter...if you cant kill it with 2 rounds of dirty06 you either cant shoot for shit or the makers of Jurassic Park will make a fortune from the movie rights. my theory is to find out which barrel is closest to sights/most accurate and develope load for that one barrel....load second barrel with big heavy slower cast loads...so you can whallop close animal in the bush without using accurate /expensive load and have 2nd one instantly if needed...
if thats what you want to buy/own you go for it Wink

Have not been on here for a while.
Thanks itrh will follow up on that info.

Rimless cartridges are said to be less than ideal however these rifles were as far as I know only available in NZ in 30-06 and 45-70.
I have one in 45-70 so another in 30-06 would be a nice 'pair'.

Double Barrel

A double barrel rifle always appealed to me, especially as my main hunting was in the bush with some long shots, but mostly at open sight range.
The configuration of a double rifle is such as that it is best with a rimmed cartridge, just like a shotgun.
This is how I went about converting a under and over Baikal shotgun to a 303 British double rifle.
There are a few double rifles around and I made a point of examining them to get an idea of proportion and found the barrels to be unbelievably thin so I used the formula s=p*(R<+r<)/(R<-R<), whereby s=lbs/sq”, p=pressure/sq”, R=od radius”,r=id radius.
Juggling the od. around for a 30 cal. Showed that a 0.625 od barrel had a metal stress in lbs/sq” of about equal to the chamber pressure according to all the research I managed, yet the yield stress of the barrel steel about 2.5 times that of the chamber pressure or better than 2 to 1 for that od.
Then I looked at the forward and aft pressure, that is the force on the action face supporting, for the shotgun at 16000 lbs chamber pressure it was about 8000 lbs, for the 303 chamber at 50000 lbs chamber pressure it was near enough the same.
Then I looked at the rearward force action on the action and stock, and the force required to accelerate the barrels in the rearward direction, bearing in mind that the rifling applied a force away from the action. Research in the British Military publication satisfying my concerns, I cannot remember the details of this, as, it was over 40 years ago.

The Baikal barrels are fitted into a part called the monoblock, the mono block is the bit that holds the barrels and contains the locking lugs, a very good example is the Baikal single shot firearm. Common practise seems to be the monblock system rather than the forged barrel method.
In my project the barrels were held into the monoblock with a cross pin and loctite, The agent for loctite who paid regular visits to the shop I worked in took an interest in the project and imported a special grade for me to use. It worked.
Tony Hawkins owner of Hawkins Arms and engineering was a good friend and we worked on some commercial design and build jobs together. Tony procured and chambered the barrels but I turned them down and finished them.
At about the same time all this was happening it became popular for trap guns to have split barrels, that is no filler between the barrels, I copied that idea as it was usual for a double rifle to be regulated for a given load, this meant mucking about endlessly soldering and re-soldering the barrel filler strips.
My way was to make up a slip on foresight, come barrel joiner, come impact adjuster which fitted at the front of the barrels, a work of art, magnificence in its inspiration and execution, I was very proud of it and it worked very, very well.
The bluing was carried out by a professional.
The woodwork was left as original.
I sold it to Ron Dent.
I do have on hand another almost finished monoblock for a Browning 12 gauge superposed shotgun available for some as a project
