    .308 Load Data

    I have a BUNCH of .308 load data. Maybe getting started with this will motivate me to compile it.

    Lets start with . . .

    49.0 Varget
    130gr barrier bullet (look at the 300 BLK thread for a description)
    Winchester Large Rifle Primer (WLRP)
    2.697 C.O.A.L.
    Tight crimp (Lee factory crimp die)

    I have not had the opportunity yet to chronograph this load. But based on my cyphering it should be running in the neighborhood of 3600-3700FPS. It does not show overpressure in once fired nickel brass.

    As always: You are just plain insane if you use my data without starting well below it and working up from there in small increments.
    I'd rather be lucky than good, but I'd rather KNOW I'm good than HOPE to get lucky.

    Darn. I forgot about this.


    Anyway . . . I worked up a new recipe today. These 130gr "barrier" bullets . . . don't seem to be (actually) available outside mil and leo circles, but I'm betting just about any "standard shape" flat based canelatured bullet is going to load pretty close to the same. In fact I used data for a HDY 130gr SP FB bullet as a starting point. Then worked the COAL and charge until I got what I wanted. Hodgdon's data said they should be running ~3089 FPS.


    51.2gr BL-C(2)
    130gr "barrier" bullet
    Winchester large rifle primers
    once fired, match prepped FGMM brass
    2.688 C.O.A.L.

    Chronographed four rounds:

    3093
    3093 (duplicate)
    3088
    3089

    I threw the first shot low and right about 1/2 inch, but the next three overlapped each other at 100 yards. Easily under 1 MOA.

    Remmy 700P, 24" tube.

    Kind of OT but I found this reloaded 308 round under the table in lane 12 at talon a few weeks ago.

    Case was trimmed and de-burred bullet looks like a Corelocked Remington. Possibly pull marks on it. Case is FC.

    And little to no crimp.

    Anyone recognize this?

    Not I.

    But it sure looks like whoever loaded it needs to read up on the purpose of the canelature.

    . . . or maybe they trimmed the case too short and had to have the bullet stick out that far to make 2.800 . . . . who knows. Folks do some crazy stuff . . .

    Maybe they were of the mind that "more bullet in the rifling is better", like .040!

    I'm just going to pull it and recycle.

    The cannelure is worthless if you're not going to crimp... you should see some of my 6.5 CM loads using the 120gr SST... the cannelure sits WELL ABOVE the case mouth... no issues at all.

    By the way, WTF is a CANELATURE?... lol
