Double Rifle 30-06 load selection

[DM~]

I have been reading about the convergence of double rifles for years and only seen logic applied once.
Ray Ordorica said HIS double does not converge but shoots parallel. (This does not mean the barrels are installed parallel, the regulation must account for differences in recoil effects from right to left.)
The muzzles are, say, an inch apart, and the individual barrel groups are centered an inch apart at any range.
Of course iron sight groups an inch apart will pretty much overlap and merge by the time you get to 200 yards.

Actually, they SHOULD STAY parallel no matter how far away you shoot...

That's the way all doubles SHOULD be regulated.

i wouldn't think you would inherently build in them converging, seconding the logic that displacement variation will accomplish it in the most accurate manner over a longer range. Especially in a game situation: no one really even knows if the round was +/- an inch when you get to the game; it's not like there's a 1" circle on it's hide.

That may indeed be how you believe they SHOULD be regulated. But, alas, it is not how they ARE regulated.

It's the way mine are regulated (i own several) and it's the way the more than 20 that i have personally regulated myself got regulated.... It IS the proper way to have one regulated.

Go to one of the DR sites on line, and ask what "proper regulation" is, see what you get there for answers from those folks. Some of the DR builders will be there, like Bailey Bradshaw, Butch Searcy, and agents for Heym, Chapuis, and Verney Carron ...

You will get an education...

You may also want to try the 180gr tsx or ttsx barnes bullet used buy many ammo companies from federal , corbon , blackhills and so on. Not many bullets can out perforrn those barnes bullets on both thin skinned and dangerous game with the same bullet.

Thanks. I am well educated with regard to dangerous game double rifles. I accept that you may have rifles otherwise regulated and that there may be manufacturers claiming such regulation is appropriate. Perhaps in a double rifle designed for deer hunting (why, I cannot imagine) such regulation is even effective. In large caliber double rifles designed for dangerous game, ie double rifles that make sense, barrels are regulated to specific convergence range with a specific load. And that's the way they should be regulated.

I'm happy to be in the company of Butch Searcy, Heym and many other DR builders in reguard to "proper" regulation.

You of course, can regulate "your's" any way you want...

The rest of us can use out DR's at longer ranges if we want, we aren't locked into a "specific" range, and then try to guess where the bullet will go beyond that!
