My 527 has 1:9 twist. I have shot 35 grain up to 75 grain and all shoot 1" from the hood of a Ford truck. I don't know if it would do as good on a Chevy, probably not.
Yes I noticed. I may not achieve the higher velocity of a longer barrel, but I'm sure the accuracy is the same or better. Probably will never know as I don't intend to put a 12x scope on to find out. I do have a 4x so 50 yards is doable.
noticed mine ( that i just purchased ) has a single set trigger which has a very nice trigger pull... my other 527's do not have the set trigger... the new 7.62 X 39 may end up my favorite to shoot...
hmmm... wonder if the set trigger groups are available to put in my 22 Hornet & 223???
