I am currently looking at the CZ 527 Varmint Kevlar in .223 and had questions about rate twist and bullet weights. I know that the CZ Kevlar has a 1:9 twist rate. I know that 1:9 is better than say 1:12 for heavier bullets. My question is how will the 1:9 affect say WWB 45gr. bullet or a Black Hills 55gr.?
I currently don't have the time or money to start reloading right now.

TIA,
Justin

I don't shoot factory amo but 55's shoot as well as the heavier bullets in my 1/9 savage tactical. 40 N BT's Shoot almost as well as the 55''s
 
Welcome to the board 308!

1 in 9 twist barrels generally are fincky about the range of bullets they shoot well. I would go with Black Hill's 52gr HP's first. Then, 55gr SP's. 9's generally like 55gr range best. PMC 52gr match is another good factory load but may be hard to find.
 
I have said rifle, and mine shoots win white box into the mid .5's for 5 shots, although I prefer black hills 50 vmax reman stuff, because the white box isn't loaded that stout
 
I have same rifle and it shoots 40 V-Max's
Well under MOA.
My old 12FV with 1:9 shot the same load under .4
MY CZ shoot's 55 V-Max's under .5
This is 5 shot groups.
