Personally I find the sporter barrels much more attractive for hunting. As I have gotten older humping extra weight and bulk around has lost it's appeal. Having a sporter barrel shortened threaded or both is a task that can be accomplished by most any gunsmith. 5/8x24 is the thread pitch on the 10HH as well as the 10PC and makes it compatible with a lot of .30 cal muzzle devices. Are iron sights a necessity? As stated above installing a barrel that already has them on a different action definitely complicates things beyond the average tinker. Here's a handy little carbine I put together from starting with a left handed wood stocked blind mag model 11 in .243.
It now has a synthetic stock(converted from right to left), detachable mag,and a shortened to 16" threaded and braked sporter barrel (gunsmith shortened crowned and threaded it for me). All the parts were purchased from the classifieds here and it was a fun project that gave me just what I wanted. A light handy powerful little carbine (37" overall length) that wont kick the snot out of me.
