    Chrono'd muzzleloader velocity - what are you seeing?

    Mainly interested in traditional gun velocities for rbs and conicals but feel free to list some of your inline velocities too for comparison - thanks!

    I have never chrono'd any of my guns mostly because I do not have a chrono.
    I have always gone by group size. I shot a lot of offhand matches in my younger days and pretty much held my own. I shot some rest matches later in life and thought about getting one to help tweak my groups.
    There are so many variables in loading, the whole process it makes really difficult.
    Don't let me discourage you. There is alot to learn.

    People say money can't buy happiness But it can buy me a Marlin and ammo to shoot in it, dies, powder bullets...

    I have one and the only thing I cronied was a pistol load. I'm afraid to know what my .45 250 grain sabot is doing at 90 grains pyrodex. I'm afraid it wouldn't be efficient enough. Its been killing deer up to 120 yards since Y2K.

    Shot a .54 patched roundball over someone else’s chrony years ago. That rifle has a 31” barrel, using 120 grains of Goex 2F, and the MV was 1,740 fps. With my own chrony, I’ve checked my inline’s MV. The caliber is .50, using a 290-grain Barnes bullet in a sabot, pushed by 130 grains of Pyrodex. MV is 1,830 FPS.

    I’m not sure about my 54 cal deerstalker with PRB and 100grs Pydrodex RS.

    T/C Encore
    110grs BH209
    CCI 209m sparkler
    Harvester Crush Rib sabot
    Barnes Original or Speer 300gr .458”

    1900fps


    I may try some .458” 405’s this fall.

    CVA Accura V2, 50 cal, 28 inch Bergara nitride barrel. Shoots 300gr powerbelt platinum with 2 Hogden Triple7 magnum 60grain pellets. 1831 fps average. Extremely accurate three touch at 100 yards, off a rest of course. Yes it’s cheating but Damn!

    I always chronograph every shot i take at the range, lining the chrono up with the target. The results I am sharing is based upon many shots and years of recording data. All of these loads are PRB of appropriate size, unless otherwise noted. I always use .015 patches, no matter what gun I am shooting, the exception being the 20 gauge where I use a .610 ball loaded naked with a wad over the top to keep it on the charge. I use only Pyrodex P or Goex FFFg for all my shooting, they are readily available where I live. Those two powders are very similiar in performance through my guns, with Pyrodex usually a little faster by 20-30 fps on average.

    with 510 gr. minie ball, sized to .580 40 grains, 910 fps 60 grains 1030 fps 75 grains 1100 fps


    These are my results in my guns, but should be pretty representative. Many things effect velocity; ball diameter, patch thickness, cap manufacturer, temperature, etc. I would spring for the $100 bucks or so, and get myself a basic chronograph, I find it to be an invaluable tool and a real eye opener. For example in MY guns, the difference between 60 and 75 grains is almost nothing in the real world of hunting, so I very rarely use 75 for anything. If I want more velocity, I just jump up to 90 grains. Guys who have shout in-lines over my chrono are always shocked to see that 150 grains give little or nothing over 90-100 grains in the same gun, except for kicking like a mule and a loss of accuracy.
