    well i am trying to figure out what i will build next and high on my list is 7mm-08 I would like to shoot the 162 amax with rl17 or any other powder that is consistent and will provide velocities over 2700fps. I have also toyed around with the idea of using the 308 palma brass with small rifle primers has anyone tried this.

    looking for any experience with this cartridge and bullet combo.

    thanks scott

    I have used WIN760 and the 162Amax. Barrel lenght was 20in and I was getting 2640fps with it. 760 isnt my first choice in powders, but that is what I had at the time for the 7-08.

    I am getting ready to slap together a fast twist 7mm geared around the 162 A-max. I love the 7-08, but will go bigger. Probably 7 mag, maybe 280 Rem, as I only have a long action available right now.......

    do the 284 you won't regret it.

    i just ordered the barrel for the 7mm-08 3 groove 9 twist.

    I have a pound of RL17 sitting here along with some 162s. I'm hoping that the RL17 will take the place of the VV N550 that I have been shooting. Only problem is it will probably be Sept. before I do any testing.

    Ive been getting right at 2800 with N550 and no pressure signs in a 29 inch barrel.
     
    Re: 7mm-08 w/162 amax and rl17 anyone?

    It will either be a 7 RM, or a 284 Win. Just not sure yet. I have a 700 long action sitting here with a burned out 6mm-06 tube on it.........

    I went with a 280AI, pushing a 162 Amax at 3000fps with 4831sc. I have no regrets, it shoots great.

    how close are you to max pressure? thinking i may have to run a 24" tube

    Since Alliant lists 44.0 gr RL17 as MAX for a 160 gr Speer BTSP, I suspect that 45.0 grs and a 162 A-MAX is already at MAX pressure.

    This load works fine in MY rifle- even in this insane heat and humidity we have had as of late, and some long strings of fire.

    Primer pockets still tight after 6 firings on some of the brass. Bolt opens with ease. I did go to 46grns but got some heavy bolt lift.

    Use common sense and work up carefully.....
     
    Re: 7mm-08 w/162 amax and rl17 anyone?

    rojer that i will probably start around 40gr and work up. i am a very careful reloader always better to start really low.
     
    Re: 7mm-08 w/162 amax and rl17 anyone?

    Hells yeah diggler. 7-08 running the 162 amax with rl-17. Sounds like a great combo. 338's together and in a while a couple 7mm's. I'm stoked.

    Re: 7mm-08 w/162 amax and rl17 anyone?

    wow thats crazy, hopefully it will be faster than that, it seems like rl 17 is a magic velocity powder, i was getting way more speed with my 284 than i thought i would. on the bright side it looks like 40gr is a good starting point.

    40.3gr IMR 4895 coal 2.935" 7-08 R-P brass=2723fps, single digit SD
    1500asl 80*F ~3000DA
     
    Re: 7mm-08 w/162 amax and rl17 anyone?

    Just wanted to keep this thread going....

    I am up to 41.5 grains of RL17 averaging 2538 fps
    SD of 17
    308 win sized down to 7-08
    Win Primers
    DPMS platform 22" barrel
    (bear in mind I am restricted to mag length)

    No pressure signs yet... and the SD has been decreasing as the powder charge goes up....
     
    Re: 7mm-08 w/162 amax and rl17 anyone?

    I loaded up some all the way up to 45 grains. I'll report back later in the week.
     
    Re: 7mm-08 w/162 amax and rl17 anyone?

    I was able to push to ~ 2650 fps.. anything faster and I am blanking primers...

    I'm sure in a bolt action with extended mag length higher speeds can be accomplished...
