[QUOTE="Guy M, post: 159185, member: 8622"] "Are there any criteria for choosing barrel length other than balance and aesthetics?" Velocity. Sometimes I think of it as "free velocity" because it doesn't take a bigger powder charge to get the velocity, it just comes as a benefit of the longer tube. How important is high velocity to you? A 24" barrel for that .243 is good, a 20" will likely churn up measurably less velocity while a 26" - 28" tube will give ya more. How much? Hard to say... There are charts but I've been surprised a time or two. Obviously a barrel can be too long, and can make a rifle clumsy to handle. That depends on the application. I've got a match rifle with a 30" Palma taper barrel on it - that works out real well for me. But it's a match rifle, not a hunting rifle. I agree that for a general purpose hunting rifle, 24" works out real well. Regards, Guy [/QUOTE]
