Thanks again! No real gain or loss in fps or accuracy in short to medium yardages under yards there is a slight advantage in 30"to 32" barrels in long range accuracy over yards using to gr bullets with a slight increase in velocities of to fps, not a big deal unless trying to keep sub-sonic down range for accuracy.
The 7. As the 7. Most factory rifles use a twist for use with bullets ranging from grs to grs for hunting. The varmint rifles generally use a twist for bullets under grs. You's be good with a twist rate and a 20" to 22" barrel to cover most if not all you needs in a. Pretty versatal cartridge when you really look at it. Many years ago, experts at Shilen barrels and top benchrest shooters did extensive experiments and discovered that a 22" barrel is the absolute best length for accuracy.
This is the best length for a. You are not shooting extremely long range like Palma competition and you are not carrying a. If you find a rifle you really like, you will notice very little difference with a 24" barrel. At one time in my hunting career, I was a carbine man. The shorter the barrel, the better. Over time, I grew to prefer more barrel length, both for increased velocity and steadiness in aiming under stress.
I have never found any great advantage in shorter barrels, even when climbing trees, because I avoid climbing with the rifle at hand or slung over my shoulder. I think 24" is about right for most calibers now. I should add that in hunting from a treestand, I think it is much safer to hoist the rifle up after you on a cord or rope, and lower it the same way when you are ready to descend. Dakota: I did not know that about Shilen, that's a neat little piece of information there.

Channel: Other. Anybody else watching the With the lower velocities of the Winchester cartridge though, the heavier bullets, with the high ballistic coefficient, tend to be a little too heavy, in my opinion. This extra weight keeps the muzzle velocity down. So a compromise of reasonable muzzle velocities and ballistic coefficient is necessary. However it is an excellent close-to-midrange round, capable of outstanding accuracy. Depending on the atmospheric conditions, that velocity is near fps.
This bullet has a ballistic coeficient of. Using these numbers in an exterior ballistics program, we find that this bullet will go subsonic past yards. If we were to go to a lighter bullet, like the grain Sierra Match King, with a lower ballistic coefficient of about. Individual rifles and longer barrel lengths will improve on these numbers, but the Winchester is never going to be a yard powerhouse. Now the selection for a barrel contour needs to be made.
This special contour that we make for Robar weighs about 5 pounds in a non-fluted condition. It is similar to the contour found on the Remington Police Special rifles and our standard 7 contour.
The barrel has enough diameter to remain stiff, and accuracy is excellent. I like this contour for a tactical rifle. If it is desirable to make the rifle a little heavier, then I would suggest using one of the straight taper barrels, like the NBRSA Heavy Varmint classification or a close variation.
If we stepped up to a cartridge like the. One of the primary reasons goes back to our already mentioned requirement for portability. A long barrel just seems to always get in the way, banging against whatever obstacle there might be.
Another good reason is rifle balance. As the barrel gets longer the center of gravity moves forward, tending to make the rifle more and more muzzle-heavy. With a can 18" is about perfect.

I'd personally define the optimal barrel length as something around 20"".
Short enough that it carries well and you're not leaving as much velocity on the table as a guy with 18". Recently built a 16" carbon fiber rig for my son to shoot and for quick and easy truck application. It lives suppressed and shoots factory Hornady gr eldx at fps which is exactly the same as my AR Not a yard killer but at hornady's recommended fps for reliable expansion, it is a yard gun all day every day.
