40-50 yrs ago it made financial sense to sporterize a MILSURP. They were cheap and available and the all up cost was less than buying a new sporting rifle such as a Win Model 70 or Savage 99. The No4/5 Enfields were the easiest and cheapest to do. M98 Mausers and M1903 Springfields involved more work and costs to re-stock, alter bolt handles, replace safetys, etc. Nowadays the economics just aren't there when you consider the initial outlay for the rifle plus parts and labour to do the sporterizing alterations. The cheapest/easiest route to go is to buy a sporting rifle for hunting.
I sporterized a No5 (bought for $18), a M1903 ($35) and a West-German re-worked M98 with a new 7x57 barrel ($40) many yrs ago. They have proven to be excellent hunting rifles, simple, reliable, good killers, true to their military pedigree, and have gotten me several truck-loads of game incl moose, bear, whitetails and mulies. I wouldn't do this today, if only because of the comparative costs of a purpose built sporting rifle.
