Hey, Could some one point me towards the right dimensions for a 22gren reamer. I plan on a 9 or 10 twist and use 55-65 gr bullets. Build on a CZ 527 action. Primary yote gun. Looking at a Lijai barrel. Hard to find a barrel for CZ. Using star brass. Leaning to 60gr Nosler BT if I can find them. I have 2 6.5 Gren built on AR platform and had this CZ 65 with sporter barrel that was too long, so it is the donor. I have a 22-243 with 8 twist shooting 80gr fast. So dont need another like that. Throat and freebore is ?

Ok. thanks. Am I making a mistake not going 7.5 or 8 twist, to shoot 80gr.

I'm probably the wrong guy to ask.
I always go for a tight twist no matter the caliber.

Same here My faster twist barrels shoot the light weights fine and handle the longer pills where as slower twist does not do well with the heavies. I would go with a 1:8 if it were me

FWIW, there is some evidence that monolithic (copper) bullets work better with faster twists. The petals tend to splay out farther and faster, especially at lower velocity.

Well I went to Mason Reamers web site and was impressed. Will be giving them a call after holiday this weekend. Looks like Ive decided 1/8 twist. I have a good supply of 80gr and a few hundred of 75gr bullets
