44 AMP said:I need to point out that there are no .45LC/.410 Bores, they are all .45 caliber barrels. They are .45 Colt guns that allow the firing of .410 shotshells.
They don't have a great reputation for accuracy with .45 Colt ammo, generally, because of the extra long jump the .45 bullet has to make to reach the rifling, which is further away from the bullet in guns made to take .410 shells as well. Some guns apparently do well enough, some don't. At pistol ranges its not usually a huge factor, but it could be, every gun is different.
I wasn't referring to the Bore diameter of the barrel, but rather to the .410 Bore shell. (Keep in mind that .410 is not a Gauge, but the diameter of the bore, ergo the cartridge's name is .410 Bore.)
So I've heard, but from what I've seen, reports of .45LCs inaccuracy out of .410 Bore cylinders is little more than assumption based on theory-craft. My Judge Magnum has been perfectly accurate shooting everything from 200gr JHPs to 255gr SWCs, despite the fact that its cylinder is chambered for 3" .410 shotshells. Furthermore, every .45LC accuracy test I've seen on YouTube has showcased good accuracy, including videos from folks who are critical of the Judge such as Paul Harrell. So in practice it would appear than any adverse effects the 2.5"-3" chambered cylinders of the Judge has on .45LC is too marginal to make a meaningful difference at average handgun distances. (Heck, Hickok45 had no problem hitting the gong at 80 yards with both the Taurus Judge and S&W Governor.)
So yeah, much like how shooting .38 Special out of a .357 Magnum, .44 Special out of a .44 Magnum, or for a much closer comparison, shooting .45LC out of a .460 S&W Magnum begets no practical loss of accuracy, it appears that even when it comes to more extreme differences between the OAL of cartridges and the subsequent distance the bullet must travel before it is engaged by the rifling, no appreciable loss of accuracy occurs when shooting .45LC out of the elongated cylinders of .410 Bore chambered revolvers.
Now, I'm sure that somewhere on the web their exists some botched or otherwise deliberately sabotaged test in which someone shoots .45LC squib loads out of the Judge/Governor which obviously keyhole out of the barrel or otherwise someone with a defective Judge/Governor with a canted barrel or fouled up rifling showcases their Judge/Governor's lack of accuracy shooting .45s which someone will inevitably call up as proof, but in my own personal shooting as well as a number of tests I've seen on YouTube, the Judge nor the Governor shows no appreciable loss of accuracy when shooting .45s.
