Re-barreling UK

[1894]

Barrels are made by machine . Chambered on precision lathes that someone skilled takes a great deal of care and time getting true to the bore before reaming the chamber correctly for the cartridge in question.

Even Remington?
Actually I think barrels are remarkably tolerant of poor chambering - I can feel my 7-08 and 30-06 M700 chambers are not concentric. Using a stoney point the bullet needs considerable force to seat against the lands to find max COL and is visibly marked on one side. Yet both shoot very well indeed.

I wonder whether this is the natural difference between what's expected of mass-produced, stalking 'very well indeed' and bespoke, F-Class/Benchrest 'very well indeed'?

There is undoubtedly a law of diminsihing returns in attention to detail and quality in all things - but those who depend on the smallest margins will, I guess, want the greatest precision in manufacture and assembly.

Bit out of context how you pasted my post ! I was describing factory against custom at the time .
Truth be known with so many folks unable to pass level one shooting test without sticks or aids first go is statically a custom barrel isn't going to help most folks . Nor is taking a massive amount of effort and time finding the best load !
To those who are capable of shooting to the highest standard , it matters though , not on all shots taken but a few yes, its nice and reassuring to know that the gun and the ammo is never the weak link the rest of the time . Also cleaning is so way easiervand faster in a true custom barrel , brass life is longer

My theory is that if under ideal conditions. I can hold half MOA or less. Then under less than ideal conditions I have a bit more leeway than a rifle that will only hold one or more MOA.
As for finding the best load etc I think that it makes a difference. In that confidence in your kit helps with your performance.

I wish I could hold a half MOA or less.

I know a lot of shooters that own 1/2 MOA rifles. The trouble is that most of those shooters are 4 MOA or more.

I suppose I am lucky enough to own rifles that are capable of that and more.

I know how barrels are chambered. What I don’t understand is how you can trust a very well respected company to manufacture a barrel but not trust them to cut the chamber

Another reason to buy a Blaser. The only time you re-barrel is when you're changing calibre!

I always thought that but after looking at many parts of the R8 I wondered about their longevity due to the use of composites and small components that didn't appear to be very robust. I wonder if all the other parts will wear out at the same time as the barrel. Yes I know that being of modular design you can just about replace everything like Trigger's broom but certainly not empirical construction like a traditional rifle such as say a K98.

Triggers broom!

Well there's a lot of factors involved, mainly time , skill level, the reamer, max v min sami spec , consentric to the bore exactly or nearnuf

I’ve said it before

Having visited a few factories where rifles are made

I’ll take the artisan (time taken skilled worker who cares about his product) over a numbed operative cutting a reamed chamber in two minutes (at best )
