This all depend what a person wants the rifle for, and where he lives! Comparing the 303 Britt to the 30-30 Win is comparing apples to lemons; they are two very different cartridges, designed for different purposes.

As far as the 30-30 Win not being a traditional cartridge in double rifles and combination guns in Europe, that is a fallacy. The cartridges are quite common in the Germanic countries before the great wars. In Germany the 30-30 Win is called 7.62X51R and was a very common cartridge in the black forest type hunting of wild boar, and roe deer, and red stag!

I had a little 30-30 Win rifle, I built on a Browning BSS action a few years ago with very short (for a double rifle) 20inch barrels. This was regulated with 150 gr Win silver tip factory ammo, and would place four rounds on a standard playing card at 100 yards over the bags. I built this little rifle for a light rifle on a sling for following the dogs on trail of Black bear, and Lion in the western USA mountains. However I use this rifle for black bear over bait, and deer in the woods on New Mexico. The fact is in the USA any country store has 30-30 ammo on the shelf any day of the year, and the squared off nose is no draw back IMO. I have killed mule deer with one shot at over two hundred yards with a 30-30 lever gun with 20 inch barrels, and the double will do it as well if you can shoot it.

NOW! If I could find a Britt double rifle factory chambered for 303 Britt, with barrels that were not ruined by Cordite/corrosive primed 303 mil-surp ammo then it would be a zebra of a different stripe. But for woods hunting in Tennessee I’d go 30-30 every time .

Resale of the rifle chambered for 30-30 in the Eastern, and southern USA would be far better than one barreled for 303 Britt today.

…………………….Just one man’s opinion!
