Pro H. 460 S&W Twist Question

[Davemuzz]

Midway is having a sale on barrels (imangine that!). They have the 460 S&W in the Pro Hunter with a 1-18 twist (20") and then they have a 1-16 twist (15") Encore barrel.

Now, I realize the 15" is for the handgun only, but it's the barrel twist that I "don't get". Is it because the 15" is shorter that it has the faster twist? (I would guess this). I know the Smith handguns have "gain twist".

I guess I just figured if the shorter barrels have a faster twist, wouldn't a longer barrel be better with the same faster twist....just because it's longer? (or maybe it's like taking asprin....you know....two is good....but 22 isn't good?)

Of course, maybe what i have said makes absolutely no sense at all to normal people.

Dave.

The pistol barrels are more often used for lighter, shorter bullets and the rifle barrels most often use heavier, longer bullets and needs a faster twist.
The rate of twist relates to the perceived "normal" bullets used and is fitted to that use. The guys who shoot heavy bullets with long noses are at a distinct disadvantage unless they custom order a barrel.
