458LOTT 22" or 24" barrel?
#80946 - 19/06/07 06:24 PM

Would a 22" barrel be ok for a 458LOTT taking in the possibility that 550grn Woodleigh bullets might be used?

24"

22 is damn short.

Just my HO.

A 22" would work just as well. It's the twist rate that is important. Lija calls for 1/14" which seem right.

I use a 22" barrel on my .450 Watts and use a 20" twist, which allows me to shoot .450 Watts and .458 Winchester interchangeably (nice option to have in an emergency). According to John Buhmiller, who was my guru in such matters, the 14" twist was unnecessarily fast, and would not allow the use of both cartridges.

When you consider that the standard .45-70 twist is 20", using much lower velocity, then you wonder why Winchester went with the faster one. (The twist used for the .470 NE is even longer: 21".)

A 22 inch barrel on a bolt gun is about the same over all length as a 26" barrel on a double rifle and just as handy. Using a cartridge with an expansion ratio like the Lott, you're not sacrificing enough velocity to make a difference.

He was talking about using a 550 gain bullet.

The .45-120 3 1/4" 550 Sharps used a 550 grain bullet with an 18" twist and that with black powder velocity.

Cannot agree more. 24" is nice to go fishing in open seas.

My 458 Lott came with a 24" barrel. It seems just right. I can balance it on one hand.
