Thread: Quickload Values for the .260 Rem ?

    Quickload Values for the .260 Rem ?

    Testing working-up loads for my .260 this afternoon. Sierra Prohunter 120 grain bullet from a 20 inch barrel.

    43 grains N160 posting 2,670 fps with a maximum spread of 32 fps.... then the chronograph packed up !

    I have fired a few loads of 44 and 45 grains of N160 and all seems fine, with no signs of excess pressure at all. Speer gives 45 grains as the maximum load for their 120 grain bullet.

    I have managed to shoot an inch and a quarter group, with the 45 grain load, using a 6x42 Swaro scope with 4A reticule, so plenty good enough for stalking.

    Could someone tell me what quickload gives for 44 and 45 grains N160 please ?

    I was testing my 260 Rem this morning with 123 gr A-Max, 44.8 gr N160 and Nosler brass. Seemed to work in my rifle, so I'm going to try some more and will chrono them next time I get a chance.

    Regards

    I have an old QuickLoad but for the 120gr Nosler Ballistic Tip at OAL of 2.8" gives the following out of a 20" barrel:
    44 gr = 2586 fps
    45 gr = 2651 fps

    Reduce the bullet length to 1.08" (Sierra), all other things equal it gives 2527 fps and 2589 fps respectively.
    Comparing top lads there is a little over 4% difference in fill ratio, hence the lower velocities in the second load.

    Hopefully that'll do till someone with a modern version turns up. Still, it sounds like your barrel is pretty fast based on the QL stuff.
    Any Questions Feel Free to PM me

    Thanks Jim. Yes my barrel does seem quite quick when compared with those numbers.
    Speer give 2,760 fps for the 43 grain load, fired from a 24'' Remington 700, however in their write-up they state that the 20'' barrel of a Remington Model 7 posted speeds of 80 to 140 fps less. So it looks like my rifle, posting 2,670 fps (90 fps less) is consistent with Speer's findings.
