Yes, both 53921 and 29317 utilize the same exact bullet, but at different velocities. According to ATK's own data, the latter clocks an additional 130 FPS from the muzzle of a 2" vented test barrel.

Do you have any test data showing what kind of velocity or expansion we can expect from either load when fired from a service length barrel? If not, statements such as "a 5 inch barrel isnt going to increase the velocity of the .38special load that much over the .357mag load" are nothing more than conjecture.

Whose "lab testing" are you talking about? Where can we find it?

Really? Why is that? Who performed these tests? Where can we find the data for them? What protocols did they use?

What evidence do you base that on, if you don't mind me asking?

I would, but I want to keep things civil and not get a ding from the moderators.
