    This quote is a little sad IMO.

    I hope you don't feel the same way about vehicles, women, or food. 😬🙂

    I chronographed Remington 125g JSP today. The temperature was 32 degrees with a wind chill of 23 degrees where I conducted the testing. The chronograph was placed 15 feet from the muzzle.

    1-Cimmaron El Maro .357 Magnum revolver with 4-5/8" barrel: Average Velocity-1370 fps, Extreme Spread-41 fps, Standard Deviation-15 fps.

    2-Taylor & Company Winchester 1873 .357 Magnum rifle with 20" barrel: Average Velocity-2104 fps, Extreme Spread-64 fps, Standard Deviation-24 fps.

    3-EMF Hartford Winchester 1892 .357 Magnum rifle with 24" barrel: Average Velocity-2160 fps, Extreme Spread-63 fps, Standard Deviation-22 fps.

    The 1873 barrel is 15-3/8" longer than the revolver and there was a 734 fps increase in muzzle velocity.

    The 1892 barrel is 19-3/8" longer than the revolver barrel and there was a 790 fps increase in muzzle velocity.

    Note that a 4" increase in rifle barrel length resulted in a 56 fps increase in muzzle velocity.

    Both rifles push a heavier projectile faster than my M1 Carbine pushes a 110g JSP.

    Nice info, thanks for sharing!

    Yeah, I was kind of thinking that there would be a point length-wise where a longer barrel would not produce much of gain (if any). Ballistics By the Inch is interesting to look at and you can see which calibers and what barrel length peaks and then begins to degrade velocity for a given caliber.

    I don't want to use the word "quieter", can you tell a difference in muzzle blast between the 20 and 24 inch barrels?

    I cannot tell any difference in the muzzle blast or sound level.

    I used to have an 18" barreled Marlin .357 that I could shoot without hearing protection (of course I have low-level tinnitus so YMMV) but it was bordering on needing plugs.

    Thanks. I have two 357 leverguns, 18" Marlin and 16" Puma, and don't remember a difference between them either. 38 Spl is very quiet in the Marlin (won't cycle correctly in the Puma).

    Thank you for posting the velocities as well.

    Ammunition C.O.L. is critical in the Rossi 1892 action. I reload cartridges using .357 brass loaded to .38 Special velocities for reliability in my EMF 1892. Finding factory .38 Special cartridges that feed reliably in the Rossi 1892 takes a bit of experimentation with different ammunition.

    You can see where the cartridge stop should prevent the next round feeding, but mine will let a second round pop right into the action. I also just shoot 357 brass with milder loads rather than fighting it to run 38 Spl.
