Perhaps the very cheapest prefits, like the ones from ER Shaw are the ones that Hired Gun is referring to. (to avoid) I have tried Mc Gowan, but since they could not deliver a barrel in 6 months which was promised in 4 weeks and were evasive when contacted, I cannot recommend them.
The fact that some barrel makers like Lilja and Brux do not produce prefit barrels, by no means serve to justify a claim that a prefit barrel is in any way inferior. It is merely a fact that those makers have more than enough demand for blanks (which they sell at the price of a Shilen prefit) and they have decided to focus on their core processes (blank making & hand lapping) instead of adding the peripheral processes needed to produce turnkey barrels.
One of the big issues in the industry is the popularity of the Remington 700 and the fact that smiths that accurize the receivers do not adhere to a standard protocol (since in fact the smiths remove only enough material to clean up features). So as a result, the dimensions of accurized Remington receivers are scattered all over the place, and to accomplish a good barrel fit on those receivers requires every barrel tenon to be cut for the individual rifle. Savage does not suffer from the same malady.
I would have to agree with Hired gun and Shortgrass based on my experience with pre-fit barrels and pre chambered barrels.
I have worked on many "Pre fit" rifles and the term Pre-Fit it's self is not good. It is just another factory take off in my opinion. The only good thing I can say about them is that they give Gunsmiths lots of work. also a savage pre-fit is one of the worst because most people that buy them think that it is easy to just screw them on and they are good to go.
Head spacing is not the only critical part of the whole process of building a precision/accurate rifle.
Here is a list of some of the problems I have found. and I am sure that my list is not the same as
Chambers= chambers cut with a roughing reamer only, chambers with NO throat, chambers with no free bore, chambers with no lead, very rough chambers, polished chambers. chambers not centered with bore, Chambers that were cocked(The front was not on the same centerline as the back of the chamber and also non SAMME chambers.
Barrel tenon= very poor fitting threads, very rough threads, tenons with short threaded length and
large/long thread relief. Tenon thread not concentric with bore.
Actions = actions that were supposed to be trued that weren't even touched, bolt lugs that were not 100% in contact with the receiver lugs. I could go on but I think everyone gets the Idea.
Really, almost just like the factory rifles are assembled.
I personally have installed only one pre chambered barrel (The last One)because I had to set the shoulder back one thread to get the chamber cleaned up concentric to the bore and to SAMME specifications. the barrel was a high end barrel but the workmanship was very poor. so the customer saved nothing because of the work/time I had to bring it to an acceptable level. (I showed him the problem before I did any work and after all the truing was done showed the finished product before I assembled it).
If you want good work you don't go to the guy at the coffee shop to have brain surgery so why would you do it your self if your not a gunsmith.
Some will say "It's just more work for Gunsmiths" Believe me, good Gunsmiths have plenty of work
hence the time it takes to get your rifle finished.
Buy what you want but most of the time you will spend more that if you started with a blank barrel
and had ONE person do all of it.
This is just my opinion for what it's worth.
