    Recently purchased a Ruger #1 in 375 H&H with a twenty inch barrel, I was wondering what the velocity difference is between a twenty inch barrel and the original twenty four inch barrel?

    No simple answer, all weights, powder loads etc will differ but here are some chrono results by caliber and barrel length...

    Great thank you for the information I'll reload with some faster burning powder and I'll chronograph the results

    If you are shooting a .375 H&H I would suggest you do some research before you start looking to faster powders for higher velocities. The information I have reviewed suggests that especially in the large magnum calibers the slower powders will actually produce the higher velocities. The shorter barrel does not change this situation. I have a Remington 788 in .243 with a 18 1/2 " barrel. I have tested a lot of different powders suggested for the .243, from the fastest to the slowest, and the slower powders have produced the higher velocities. H4350 produced not only the greater velocities but grouped them better also.
