CZ 527 with 1-12 twist.

[semperguy]

For those of you that own one of the older CZ 527s with the older 1-12 twist. Have you had any issues with bullet weights 55grn and below. I have no intention of going above that and I have found some screaming deals on the older ones with the 1-12 twist.

My 1:12 twist 527 Varmint has been sub moa at 100 yards with pretty much every hand loaded bullet that I've tried between 40 and 55 grains.

My 527 has been my main doggin gun for many years, kinda tuff to put hard numbers to it but it has to be over 2500 rounds. I only stock 40 grain Vmaxes and 55 grain soft points
Mine actually prefers 55grain soft points, The 40 grain Vmaxes are very finicky in my 1/12 twist 527 American.
