222 rem loading with win 64 gr?

[danny pay]

Hi guys
Merry christmas to you.
as we know 1/14 is too slow for 55 gr+,but which twist rate should i choose for a new barrel for my brno ? i want it too shoot factory loads 50-55 gr and as well as handloads upp to 70 gr. would a 1/12 twist be a good choice? or should i go to 1/10?
all the best
danny
