I'm wondering why would anyone don't get this:
- It takes time and money to pack and mail a rifle to a smith
- It takes time and money to ship a rifle back to you from a smith
- It takes time and money for a smith to fit a barrel
- A smith you want is usually busy, expensive and located at a significant distance
- Smiths you don't want are not that expensive and might be closer, but still first 3 points apply
- Smiths you don't want can screw up your rifle even on a simple tasks, and they do
Why would you do all that if you can get a barrel ready to go and screw it yourself in 5 minutes?
1. If I have a Bighorn TL3, Bighorn Origin, Lone Peak, Impact, ARC Nucleus, ARC Mausingfield (after certain serial numbers), Curtis Custom, AI, DT SRS, etc. - then the gunsmith
NEVER has to see the action to spin up a shouldered barrel for it. This list is growing by the week as manufacturers are improving their control on tolerances.
2. If you don't have the above actions, then the gunsmith has to see your action only
ONCE. Guess what I do? I call up my gunsmith and order a shouldered barrel to my specs. He does the job and sends the barrel to my house in the mail.
3. I get control over whatever barrel blank brand I want. Not at the mercy of manufacturers making pre-fits out of the more budget blanks. I get Krieger, Bartlein, Hawkhill, Benchmark, Brux, Rock Creek at my disposal. This means I also get to choose my contour, barrel length, twist rate, etc.
4. I'm not limited to the thinner contours. My rifle balances much better with HV and MTU contour barrels. These contours are not an option for barrel nut style pre-fits.
5. I get to use the exact reamer I want, for the projectiles I'm shooting. For my 6BRA barrel, I have my gunsmith use my own reamer. For my 6.5 creedmoor barrel, I use a gunsmiths reamer that is optimized for the 140 Bergers I shoot. It shoots lights out. I'm not at the mercy of prefits which use a generic reamer which is designed to handled most projectiles, but not excel at any given one.
6. I get control over who spins up my barrel - arguably the most important piece of a precision rifle. It's not threaded and chambered in a mass produced factory, by a guy who may or may not know what he is doing.
7. And guess what? My barrels show up in the mail, just like your prefits do. No need to send my gun off to the gunsmith.
I'm of the opinion that the outcome of all of the above makes for a better product. Yes, prefits are generally cheaper (there's a reason for that). And yes, you have to have proper planning to ensure your new shouldered barrel arrives before you burn out your current one, but that is pretty simple logistics.
I can understand why people may want barrel nut pre-fits, and that's fine. You are obviously happy with your pre-fits, and that's all that should matter to you. I'm happy that it does what you need it to. But let's stop pretending that shouldered barrels are such an inconvenience to order and install. That simply isn't true.
