Gentlemen

I own and have hunted both, Drillings [2 shotgun bbls one rifle bbl], and double rifle drillings.

They are the best hunting guns on the Planet, where fur and feathered game can be persued at the same time.

Here is my assesment. Both should have a scope in QD mounts.

The Drilling is best for those times where you are primarily hunting birds or small game, but may encounter deer, pigs, elk, bear etc.

The double rifle drilling is for when you are primarially hunting "rifle game", but may encounter feathered or other small game.

So you need to analyize your hunting style and decide which is best.

Me I needed both types.

And, I like these combination guns enough to invest in both types.

They are very useful hunting guns.

Also I will add, that here in Texas, my wifes favorite hunting gun is HER Sauer 12x12x30-06 Drilling.
It has a 4x Kahles scope in claw mounts.

With it she has taken multiple, deer, wild pigs, turkey, ducks, quail, dove, rabbit, and squirrel.

In Zimbabwe she has taken African ducks, guinea foul, franklion, sand grouse, dove, kudu and warthog.
