Then subtract the length of the ammo measured with a comparator, this gives you the length of the rifling Now you can see why the short mag (saum) looks so efficient in a short tube compared to...

This is correct. It is quite a bit shorter than the barrel looks. For instance, the OAL of a .308 cartridge is 2.800" (therabouts) so a 20" barrel will only have about 17" of rifling and bullet...

Shortening it further will be a lottery unless the GS has the measuring equipment and skill to use it.

Accuracy has a degree of alchemy involved. There are rules and exceptions that prove the rule. Some barrels with twist rates that are theoretically too slow still shoot very accurately with...

Even the finest barrelmakers will have variation in the bore and land dimensions, and no barrel is perfectly straight. So when a knowlegable gunsmith seeking the finest accuracy shortens a barrel...
