Probably been kicked around on here several time,but am going to
ask anyway....What is the heaviest bullet you guys have found
that works good in the 223 and with the 1 in 9 twist...

I thought of getting a 1 in 8 twist,but Jim Briggs told me that
the 1 in 9 will be about all I would need..This is going to be
a rifle for the grand daughter to shoot 250 yard F class with..

Thanks for any information or advice you have to offer,so I
can make sure to get a few box's of bullets on hand...
