Usually it is only meant for rare or important Milsurp rifles. It was quite common in Canada in the 50's and 60's to take any old Enfield rifle and cut down the wood and barrel to make it a lighter handier deer rifle. Other rifles that were often "Bubbahd were Mausers and Springfields.

Personally I don't think there is anything wrong with making a average M4 Mosin into a scout but I would not do it to a Finn or other rare one.

I have a couple bubbas. One is the king of all bubbas the Parker Hale custom #4.
It is a beautiful high end hunting rifle built on a Enfield receiver. Custom PH barrel, beautiful bluing and a walnut montecarlo stock. It is like a .303 cal English dangerous game rifle for the price of a Stevens.

The other Bubba I just got the other day is a BSA SMLE No1 mark3*. It has only had a the wood cut so I may restore it or build it into a scout. This is a rifle that was made after WW1 and then brought back into service for use as a Home Guard rifle although it could have been used in combat in WW2 as SMLE's were much more popular than the new no4's just like M14's were more popular than M16's in veitnam.

It is a good shooter with a 5 groove barrel and the hard to find sights still intact. Unfortunatly it was a later model without the mag cut off(very desirable both to SMLE collectors and scout rifles) or volley sights.

The thing kicks like a mule compared to the cushy montrcarlo with thick rubber pad on my PH. I polished up the brass butt plate so it is blinging.

I also ordered a 1907 bayonet and a nea6t shorter indian Enfield bayonet.

Other than not having a scout scope my bubbad SMLE is very close to a scout rifle. It uses a good cartridge ,charger loaded ,10 round mag,light and handy,
set up for a ching sling,good iron sights, Jeff Cooper actually said that the least important part of a scout rifle is the scope. It is a bit long and heavy though. If the barrel had already been cut I could see bringing it down to 18 inches and putting it in a synthetic stock but I just could not hack up even a unremarkable SMLE myself.

Actually I don't own any rifles or shotties with ducks and dog engravings (yet).
I just think in Canada that if you have to explain why you shot some home invader you are better off with a Remington 700 that looks like the cops grandads duck gun than the ones the Swat team wanted but could not afford.
