1/8 rifling is needed....kinda...sorta....
This is the bullet I use to load to (close to) M262 spec....

Without crimped in primers it is difficult to reach the real deal power factor without pressure problems....still you can get real close with Varget.....fyi...the boxer primed steel Wolf 5.56mm cases allow a higher safe pressure...they will never pop a primer...just reload them once....they work like a charm...
SOME 1/9" twist barrels will stabilize this bullet....some won't....
I am told there is a tolerence in spin and some 1/9 barrels are like 1/8.5" or so.....
Anyway some 1/9 barrels will work....just have to try....probably like the old 1/14" twist in the early A1s not stabilizing M196 ball in real cold weather...
