How important is bore axis on a pistol?
Recoil control The recoil from a fired cartridge (and the action movement) exerts a rearward impulse along the bore axis, which is commonly above the center of mass of the gun. A lower bore axis will align more of the recoil directly into the hand, creating less couple torque and thus less muzzle rise.
What pistol has the lowest bore axis?
Claiming a bore axis located just 1.7mm under the axis of the shooter’s grip, the Czech-made Laugo Alien pistol has its sights on competition.
Do pistols have rifled bores?
Most handgun barrels have spiraling grooves cut or pressed into the bore. When a handgun is fired, the rifling in the barrel puts a spiral spin on the bullet. This spin keeps the bullet point-first in flight, increasing accuracy and distance.
Does bore axis really matter?
Premium Member. physics isn’t a myth, it’s just not the be-all-end-all for firearm control. There are a whole bunch of things that help mitigate muzzle flip; a lower bore axis being one of them. Everything from the shooter’s fundamentals, bullet weight, handgun weight, firearm mechanics, etc.
Why do Sig pistols have a high bore axis?
The reason is simple: recoil management. That’s good for manufacturing, but that can be bad for perceived recoil and speed on the range. Here’s why: A classic example of a “high bore axis” handgun is the SIG SAUER P226 (pictured above and in video here).
Are pistols smooth bore?
A smoothbore handgun is technically a shotgun and must follow the regulations for them. It is, in effect, a sawed-off shotgun. Some handgun manufactures get around making them in 45LC/410 with less-deep rifling.
Why are there no hexagonal bullets?
They are pushed into the breech by mechanical action and there is no reliable way to ensure that a hexagonal bullet would be properly indexed to the hexagonal bore. If it were not properly indexed – that is, if the “corners” of the hexagonal bullet lined up with the “flats” in the hexagonal bore – it would jam.
Is rifled or smooth bore better?
The chief advantages of smoothbore designs are their greater suitability for fin stabilised ammunition and their greatly reduced barrel wear compared with rifled designs. Most modern main battle tanks now mount a smoothbore gun.
Why are tank cannons smooth bore?
The reason tank guns are smoothbore is the switch from HEAT (High Explosive Anti-Tank) to kinetic energy rounds sabot as the primary anti-tank round. Kinetic energy rounds are subcaliber rounds (smaller than the bore) and aren’t effective if the spun by rifling.
What was the most accurate rifle in the Civil War?
A single-shot muzzleloader with excellent long-range accuracy for its era, especially when used with a telescopic sight, the Whitworth rifle was widely regarded as the world’s first sniper rifle….

Are Glock barrels rifled?
Glock features Polygonal barrel rifling on all of its handguns. However, upon close observation of Glock barrels, it would seem that the lands would consist in convex surfaces − basically standard-tipe rifling lands deprived of their typical corners, or “rounded” as they’ve sometimes been described.
What does the bore axis on a pistol mean?
Check us out on twitter! In pistols, bore axis describes the height of the barrel and slide above the shooter’s grip, and while it isn’t a characteristic that all shooters consider when buying a pistol, they probably should.
Why do I have to slug my gun barrel?
Then read on!! Experiencing leading or inaccuracy with cast lead bullets are reasons to “slug” a gun barrel to determine the actual groove diameter. Once this actual groove diameter is known, then you can use cast lead bullets that conform closely to this dimension.
What kind of slug do I need to slug a handgun?
Here’s how to go about slugging a handgun barrel. First off a pure lead “slug” is needed. For that purpose the pure lead round balls as sold by Hornady and Speer for muzzleloaders are perfect. Pick one much larger in diameter than the barrel to be checked.
How many barrels can a cast lead bullet slug?
Once this actual groove diameter is known, then you can use cast lead bullets that conform closely to this dimension. This kit was designed to help you determine the ACTUAL GROOVE DIAMETER of your gun barrel. in 9 different diameters, enough to slug 5 barrels.
