Need load info

[savageshooter86]

Can anyone point me to a starting load for my AR 5.56 using the Nosler 64gr Bonded bullets?

DPMS 1-9 16"
Rem brass
Tula KVB556M
CFE223/W748

Or would I just start

Nosler list it for a 26" 12 twsit bolt gun only

One thing is, your 1:9 twist barrel might not stabilize the heavier pills. But there's only one way to find out.

Here's the data from hodgdon, start low and work up. One, note is I seat out to 2.250 (mag length) using 65gr Sierra Gamekings.
