I have been searching for "different" rifle for my own hunting. I have looked at o/u, Bergstutzen and single shots.

I want to pack one case and go hunt.

Now I have stumbled across a New Brno O/U combination in 12ga 3"/9.3x74R with 24 inch barrels and am wondering how good full length barrel inserts will work. I could get an insert for say 9.3x74R(giving me a double of sorts, a 7x57R insert for a Stutzen and perhaps a 22 Hornet insert for small stuff.

Anybody use them and what are your experiences and thoughts.

I am not looking for long range accuracy but at least it needs to have acceptable accuracy out to about 200 yards....

IvW , do you mean something like this ? We Call them adaptors . They work from a functional point of view . I have experimented with them many years ago. . Accuracy is not the best though. My own example took many cotton tail rabbits and pheasant. Is 100 yards suitable for you ? The gun l used belongs to a close friend using an Italian ( probably Beretta , if my memory serves me right ) Over Under 12 gauge . Inserts were for a 9mm

I'll be curious to see the answers. Drillings are often equipped with a shotgun insert barrel for .22 LR or .22 Magnum. I have seen a WWII era Krieghoff equipped with .22 savage HP insert. It is normally fitted for the right shotgun barrel so the set trigger can be used. Once installed they are then fine adjusted to the telescopic sight (you will have already adjusted the sight to the primary rifle caliber). They can be extremely accurate for foxes and that sort of thing from a highseat. (Like most Tetonic firearms' engineering, once fitted and adjusted, they can be removed and reinserted with no loss in accuracy of the sight setting). My guild drilling with a Krieghoff insert shoots little tiny .22 mag groups at seventy yards. I have never seen large caliber inserts. The pistol bullet inserts I have seen were generally pretty worthless.

I believe with an insert of a large caliber cartridge in a shotgun there would be an issue with the action's ability to withstand the higher pressures.

You will end up with a whole series of problems and you will not become happy,... this is what I promise.

For a good insert barrel you have to pay 1000 - 1400 € or $.... for one,...you want three, is'n it?

You need a good one badly, because it has to be adjustable to the other (9,3x74R) rifle barrel! and thouse are not cheep.

You need a strong rifle, steel not aluminium bascule! with a solid locking.

It has to be installed by a competent gunsmith, familiar with insert barrels, the maker of the insert preferably.

Because, when things go south, you can blame him!

You can ruin a good gun with a bad installed insert, and a weak gun anyway.

3 different inserts in one shotgun barrel will not work reliable.

You will spent tons of ammunition zeroing the barrels after every change.

Manufacturers say, it works without zeroing, but it does not, believe me.

I have insert barrels in several calibers up to 6,5x57R,...nothing bigger.

Especially the small calibers are extremely accurate, once I made one hole with 5 shots from my .223 at 100 m.

Not every day, but it happend.

I would look for a 9,3x74R O/U double, sometimes you can find a good used Brno for an acceptable price.

... and a combi 12/76 7x65R with an .22 Hornet insert barrel.


Diana bless you..... and your wallet.;)

Hello, saw that you want the Jeffries brass. So you an either send a USPS money order or paypal i guess, which ever works for you is fine with me at this point. If you want to us Paypal use [redacted] friends and family and dont mention gun stuff at all or they will go bananas! LOL!

Let me know what you want to do.
Thanks,
Rob
