    Max Bullet Grain in the SCAR 17

    Pretty sure I am getting a SCAR 17 but I was hoping someone had the answer to this question.

    What is the max bullet grain you can shoot out of the SCAR 17?

    I know on the M1A the max grain is 175gn, anything above that is not recommended.

    Thoughts?

    175's and 178's shoot great. I may have to try some heavier just to see..........dj

    Isnt the problem that the overall length wont fit or feed from the magazine? Does a heavier grain bullet get longer than the lighter ones?

    Of course I am compensating for something.... If I could kill something at 300 meters with my c*ck I would not need a gun!

    Correct the higher the grain the longer the bullet

    I would love to see that. What grain weights do you think you will try first?

    About the longest standard round for 7.62 NATO is M118 Special Ball with a 175 gr boattail bullet and an overall spec length of 2.83"

    As long as you don't exceed the OAL you should be fine with a 175, 178 or even 180 grain bullet. Your problem going heavier is that the 1:12 barrel twist rate won't do you a lot of good with anything heavier. You want to shoot heavier, you'll need to go to a 1:10.

    This was my line of thinking as well and where I was going with my question

    Barre length is a factor also, slower twist rates, shorter barrel lengths, and heavy bullet weights are not going to do well at extended ranges, higher bullet weight, lower velocities and a lower bullet RPM will cause the round to destabilize sooner.
