22-250 is a little different than a 20VT.

Something else to keep in mind when you go shorter, even shooting mine suppressed, they're definitely a fair bit louder too. |

i'd say a 23" barrel

Just as a comment regarding The Warehouse testing, the cartridge being tested/used was the 6PPC which has a totally different (and smaller) case capacity to bore ratio compared to a 22-250......Kiwi

The cartridge powder capacity and barrel caliber has little to do with the harmonics of a 21.75" barrel being the ideal for accuracy. It might not really matter to you if you can not hold the rifle steady as a rock while lining up your target, but if you were to go and spend money anyway on a barrel, would you not want to give your rifle the best possible chance of putting the bullets in the same hole? I would not leave it up to chance if it were me. I would go with what a couple thousand hours of shooting proved to be the most accurate.
Then again, you are hunting varmints, not bullet holes stacked on top of one another, so you actually may be better off with more velocity all things being equal, a varmint at 4 or 5 hundred yards will not know the difference if you were just a whisker off his nose when you sent him flying to the alfalfa fields in the sky. The bullets you are going to shoot probably matter more than the barrel length as long as you are consistently burning nearly all your powder. I would still read that article if I were you, it is full of insight on what makes an accurate rifle shoot tiny groups. What it does not have is field shooting experiences. Shoot what you want, if you hit it and you are happy that is all that matters as long as you are ethical enough to be able to stare at yourself in the mirror and confidently say that you did what you could to not wound or injure and animal, but put it out of it's misery with a clean shot. |

I really don’t think the Velocity loss is as much as you think. At least that’s been experience. My .22-250AI had a 26” Barrel when it was new. I shot the 60 grain Bergers at 3800 fps. When I got my Suppressor I cut off 5” and that same load is running 3670 fps. Velocity loss of about 130 fps. Not a big deal. I know if I went down to the 55 grain Bergers I could get over 3800 fps.
I have a .204 Ruger that had a 24” Barrel shooting 35 grain Bergers around 3900 fps. Cut off 4" for my Suppressor and the same load is still running around 3825 fps. For a velocity loss of about 75 fps...Again not Bad..... Good Hunting Chad |

I am new to these micro/varmint calibers, with most of my experience in the .223 - .308 size. In my opinion there is no "Optimal" barrel length...the cartridge capacity, powder selection (burn rate), as well as the bullet selection can be tailored to any gun. If I am having to massage every ounce of velocity out of a cartridge then perhaps I need a larger cartridge or more efficient cartridge that I won't have to pushed as hard.
For me, the Optimal barrel length is determined by the purpose of the rifle. There is an "efficient" barrel length where for a given cartridge the vast majority of the velocity is achieved. Ultimately, barrel length is a balancing act of (1) required velocity to drive a bullet to a desired max distance (case capacity, powder burn rate, and bullet aerodynamics) and (2) intended usage of the rifle (walking or stationary, offhand or supported shooting, low or high volume of shooting) in which weight and balance becomes critical. My preference is 20" barrel on light sporter rifles for carrying and 24" barrels on target/bench rifles. For AR15's shorten the aforementioned lengths by 4" or more. Oh Yeah - I am willing to trade velocity (shorter barrel length) to accommodate sound/recoil management of a Suppressor. Last edited by Oso Polaris; 05-22-2019 at 09:33 PM. |
