New DPMS

[Ruger No. 1]

My dad picked up this DPMS yesterday. Its a 223 with a 20 inch bull barrel 1 in 9 twist Now, What bullets weights would be best for that twist?

[OldTurtle]

I have a 16" bull barreled DPMS that will shoot every thing from 50gr up to 64gr very nicely... I could probably go even heavier, but just haven't had the need..

My other AR has a 1/14 twist and shoots 35gr - 55gr in small groups..

IMHO, the 1/9 is an extremely versatile twist rate...especially in an AR...

my 20" 1-9" 700 keeps the 75 amax steady.

Sierra or Nosler 69 gr HPBT with 25 gr of H4895 with CCI450 primers.

I was talking to a guy at the range the other night and he was saying DPMS was junk, he said RRA was 10x better. any truth?

[acloco]

None....whatsoever.

The truth is....there is only so many CNC machines in the U.S. that are carving out AR uppers and lowers.

I have a CMMG lower and a DPMS lower - I will be $1 they were machined on the same CNC...as the radius lines on the cutters are identical.

Not concerning mine,,,,, I've shot several 3-gun competitions at the "big money" matches ($160k on the prize tables) as well as locally and never had a 'hiccup', it feeds from most mags, and is accurate enough for most 200yd egg shoots...

I'm not saying that any other brand is better, or worse, since I've had very little experience with most of the other factory brands...
