    284 Hammer projectiles in my 7mm-08

    I have been experimenting with 140 gr Absolute Hammer in my 7mm-08 . (Remmington 700 )
    settled on 44.5 grains of 2208 ( 45gr is hot/ sticky lifts on bolt ) V=2900 ft/sec ave
    No pressure , in Norma brass , CCI primers , COAL 2.8 , Barrell at 22 inch , accuracy better than 1 MOA .
    My calcs = 1800 ft/secs/ 1000 ft/lbs at 600 yds

    I like these projectiles , and have used them on deer . They work well . Look them up https://hammerbullets.com/
    These projectiles are unique . They are not like other copper bullets in that the driving bands produce lower pressure that other projectiles .



    NOTE TO ALL .
    Gordons reloading tool predicted the load to be too DANGEROUS to use at well over 70,000 lbs of pressure and a velocity of about 3000 ft/sec .
    I worked this load up from 43 grains to 45 grains. Pressure signs were evident at 45 grains in slightly flat primer and sticky bolt lift, and i "felt "the load in the recoil.
    I am confident to tell all , there is no doubt this is compressed load. However, there was nothing particularly noticeable in the building of the load . I did not measure "neck tension " but did add the very slightest crimp pressure

    Use this info at your own risk
