Looking to buy my first centerfire rifle, in 6.5 Creedmore, for long range target shooting. I thought a longer barrel = more velocity, but saw a video by .22 maker Vudu saying the powder is spent in .22 at 16 inches and barrels > 20" will slow the bullet due to drag against the rifling.

The 6.5 Creedmore rifles I've looked at have barrels from 20" to 26". For this caliber, what barrel length will produce the greatest velocity and accuracy?

Thanks.
 
22LR is much different than a 6.5 creed

Accuracy isnt dependent on length

24 or 26 is normal length. Longer will be fast up to probably 30 or 32 depending if you're using the right powder
 
2-4 grains of powder vs. 40-42gr of powder. You'd probably keep gaining velocity to somewhere around 40-45". Realistic top end for barrel length is 26 or 28".
