    You can do that with a 22" barrel now. So not a huge gain. My 74 Targex are 2970 fps from a 20". Or are you thinking 3k from a 16" barrel?

    Your 74s might be doing 3k from 13 or 14 at 80000psi!

    Yuck keep your extra inchs to yourself!

    I do 2850 in an 18" now its plenty but a little more is always nice or the same but shorter.

    GRT suggests 80kpsi would give 2950ish in a 16" with my same powder and bullet. Thats what I mean as well as higher pressure helps a more complete burn with slower powders in short barrels (according to GRT and QL) if you think it matters.

    It also suggests that 2970 in a 20 is already in the 65-70kpsi realm. In most bolt actions pressure signs are often not seen until 70-80kpsi often higher
