I was wondering what real difference this 2 in difference in barrel length would be when considering shots upto and including 200 yards or so. It is hard to determine as most ballistics and charts use a 24 in as a base. Just curios. I am shooting a .260.
Thanks
 
About 100 fps muzzle velocity loss per inch of barrel. However, like tiriaq says, neither you nor the game will notice any difference at 200 yards.
 
bull####, 25-35 fps per inch at most, especially in a 260 Remington

inside 500 yards, you probably couldnt tell the difference in POI between a 20" & 22"
 
I have tikka in .270Win with 20" barrel.....and what??? nothing...as a hunting rifle it has more adventages if you compare with 22" barrel.....

I was just recently looking over a test where they started with a long barrel in .223, and cut it an inch at a time to measure velocity loss.

It was much less than expected. I can't for the life of me remember where that was... Reloader's Nest maybe?
 
Don't worry about the barrel length. Chrony your load then use the ballistics tables to get an idea of your trajectory then go shoot it at those distances to really see and confirm what it is doing, otherwise you will never know. There are far to many variables to go by book figures.
 
Interesting info ,I guess some people put more emphasis on it then truly realistic. I was not worried more curious is all, for my purposes, the 20 in bbl is easier to cart around through the thick bush I hunt in WMU62 North of 7. I will say that I am very ,very impressed with the .260 especially in my model 7 ss with talley rings and now sports a sweet little 2-7x33 VXII. 280 Ackley and Rembo may recognize this one, and it sports a gatehouse paintjob to boot, thanks guys !!!!

To be fair, Bullberry has a distinct bias toward shorter barrels. No other independent tests have borne out those results (in 204)

Should also not that different cartridges will respond differently. The more powder you're burning, as a general, the more you gain from longer barrels. The more overbore your cartridge is, the slower the powder you use, so on and so forth
