How does barrel length affect bullet velocity?
Longer barrels give the propellant force more time to work on propelling the bullet. For this reason longer barrels generally provide higher velocities, everything else being equal. As the bullet moves down the bore, however, the propellant’s gas pressure behind it diminishes.
What is the effective range of a 260 Remington?
Overall, the 260 is a great caliber for mid range sniping (out to 1000 meters) in smaller to midsized weapon systems as it far exceeds the ballistics of the . 308 and with less recoil. The round inherently has good accuracy and enough energy mixed with outstanding long range performance to make it a serious player.

Does a shorter barrel increase velocity?
All we would learn is how much velocity was lost per inch with that cartridge, that load, in that barrel. Case design matters. Short, fat cartridges are more efficient than long, slender cases, and they tend to produce more velocity in shorter barrels.
How much velocity do you lose with a shorter barrel?
As a general rule, an inch less barrel will cost a bullet between 25 and 50 fps velocity. This varies depending on powder volume and the burning rate of that powder. The more powder and the slower its burning rate, the more barrel volume needed to burn it.
Who makes the best 260 caliber rifle?

5 Answers. The short answer: Yes, a longer gun barrel improves accuracy. Theoretical accuracy of handguns and rifles is driven by rifling, barrel length, and bullet mass.
Are shorter barrels more accurate?
Overall, as demonstrated in the accuracy charts, the shortest barrel length provided the most consistent accuracy across the board and the longest length proved to be the least accurate with the same loads. The data also shows that the so called “MOA” a rifle can shoot changes with distance.
Which is better 6.5 Creedmoor or 260 Remington?
260 Remington ammunition, the 6.5 Creedmoor tends to perform better at longer distances. Even though it starts out going 5 percent faster than Hornady’s 147-grain ELD Match 6.5 Creedmoor load (2840 fps vs. 2695 fps), the Creedmoor’s bullet arrives at 1000 yards 0.09-second—about 5 percent—sooner.
Is a 260 a good deer rifle?
The . 260 Remington is just about perfect as a deer cartridge; there’s enough bullet for any deer that walks, yet it’s not so fast as to result in an excess of blood-shot meat.
