Barnes bullets

Bezoar · November 11, 2013, 06:26 PM

Im curious on their bullet system. They have almost identical bullets listed together and it has me confused. Is there an unlisted reason why one bullet should only be used in a .44 special and one bullet only used in a .460 sw?

They are made to work at different veloicty. The 44 dont go as fast as the 45 (460)

I don't know about Barnes bullets in particular, but the .44 Special and the .460 S&W work at MUCH different peak pressures. In revolvers, there is a potential for bullets that are too soft for the pressure "riveting" in the forcing cone and increasing pressure. So, a LEAD-cored jacketed bullet is usually constructed quite differently for these two cartridges. The Special bullet will probably have a soft lead core and a relatively thin jacket. This is sufficient for the pressures with respect to the forcing cone deformation, and helps bullets expand in an animal target. The .460 bullets probably have a harder alloy lead core and a thicker jacket to control deformation in the forcing cone, as well as to hold them together better when they penetrate a game target. But, if the bullets you are asking about are "unleaded" then the difference may have only to do with how the bullet is constructed to behave in the target.

What two bullets are you referring to?

barnes shows one bullet specified as "44 special" the ballistic datas for it are identical to the 200 grain "44 mag" bulllet, but placement of cannelure is different.

same with the 45 colt ans 460 sw designated bullet.

There ya go. Answered your own question. The cannelure is different for different length cartridges for proper roll crimping.

If the cannelure is in a different place, then you will get different pressures when loaded with the same powder charge in the same case. So, load data will not be interchangeable for those bullets.
