CZ 527 .223 Loads?

[JBM_DC]

Just curious what other CZ shooters found ideal in their CZ 527 .223.

My current rifle setup for the 527 Varmint (1:9 twist) topped with a Vortex PST 4-16.

I am currently working on a second load with the following components:

Lapua Match Brass
CCI 41 SRP
Varget (Unsure of charges until I can preform OCW test)
69 SMK

Hoping to get these shooting well from the magazine. I would prefer the 70gr Bergers, but am a little scared of trying them due to magazine length. My ultimate goal is to have a nice shooting rifle to 600 meters. Up until now I was loading 50gr Vmax loads with some success to 400 meters before accuracy plummeted.

Cant really help much, as mine is punched out to 223AI. As for the heavier bullets, they will fit. Hell, I can get 75 AMAXs in the magazine.

the 69s work very well out of my cz worked best with compressed varget loads oal 2260

The bullet is a good match.
I would look at h 4895 and 69 Sierra. 24.6 should be somewhere interesting.
You gotta do the dudilligance.

How well does the 75 Amax perform from your rifle at longer ranges?

Thanks for the info. If anyone else has anything to add that would be great.

Also how well do you like the .223 ai? It has crossed my mind several times to have it rechambered.
