In a perfect world, I'd have 2 barrels (7mm Rem Mag, and 375 Ruger) and they'd both shoot 1/2 moa or so. Is this feasible, or a pipe dream? (standard ADL contour, 24" long)
This has been a long time debate and probably continue to be a Chevy versus ford debate and
it boils down to what you want to try.
There are pros and cons with a switch barrel. the main advantage is cost. In theory all you
need is another barrel and preferably two cartridges with the same case head size, plus a
very good smith to set the barrels up where they can be set up precisely each time.
The down side to me is the fact that every time you change barrels you will have to spend
time and ammo to re-zero the rifle and with different calibers, harmonics will be different
even with the same contour barrel because of the bore diameter and bullet weight,
requiring different action screw torques possibly for maximum accuracy and a very durable
bedding job to maintain its fit after many swaps.
I am not against switch barrels but my experance with them has not been as good as two
rifles special purpose built that are not disturbed by taking them in and out of the stock.
Most of the time if you take a great shooting rifle apart (out of the stock) you have to verify
the zero and they will not normally shoot the same group size. (It may be larger or smaller
though not by much) And torque values may have to be changed for the very best accuracy.
As a hunter. the accuracy difference is not that much of a problem, but if it is a match rifle
or long shots are the norm every few thousandths can mean success of failure, so personally
I don't like messing with a fine shooting rifle.
So again , In my opinion if you have /want two different calibers for hunting you may be satisfied
with a switch barrel, especially if you switch barrels only once a year for different hunting seasons
(Varmints then big game).
The other down side that I found to a switch barrel rig was the requirements for optics were so
far apart and a compromise was needed (It was not the best for ether caliber).
Just my opinion.
