I have been sporterized Mausers since 1965.
Some of them are almost finished.
It is never cost effective.

My brother in 2014 shot a mule buck with an off the shelf Rem700 he got for $75 from the neighbor.
His shop for sporterizing Mausers is bigger than his house.

I have as much heavy machinery as he does for sporterizing Mausers, and I shot a mule buck and an antelope buck in 2014 with an off the shelf Browning 1885 I got for $1600 off the internet.

Sporterizing Mausers, you have to WANT to do it.

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway
The man who makes no mistakes does not usually make anything.-- Edward John Phelps
