60 grain partition from CZ 527 18.5 in Barrlel 1in12twist?

[bcraig]

Hi, new here with my first post.
I recently got a CZ 527 Carbine with 18.5 inch barrel and 1 in 12 twist.
Wanting to use the Federal premium load with 60 grain Partitions for deer hunting.
Figuring the Velocity will probably be around 3100 FPS or so ?
Think this load will stabilize in the Carbines barrel ?
Thanks,Craig

The 60 gr PT will stabilize in a 1:12 twist.

Hi bcraig,

I've been researching and loading up the 60gr partitions for my 22-250 that has a 1/12 twist. Maybe someone can confirm this, but I've read that this Partition was developed to stabilize in the 1/12's. I used Bergers twist rate calculator on their webpage and the Partition had the highest miller stability rating out of the bullet weights I wanted to use. If you want to try some without breaking the bank, shootersproshop sells them for a good discount.

I'm getting 3400 fps, .8-1.2 moa. I'm still playing with seating depth and primers and seems to prefer a long jump into the lands. It is extremely low recoiling in the T/C Venture.

Everyone has differing opinions on "killing power" but I have seen quite a few deer shot with 50-55 grain bullets from 22 cal rifles and most all were bang flops. I use a little bigger gun though. It should stabilize I would think.

Is the CZ a .223? Can't tell from title post and CZ does not make an 18-1/2, .22/250.

A 60gr Partition would take down any Rabbit that walks this earth. You betcha! :lol:

I just did the Greenhill calculation and it said that for the 60 Grain Partition out of a .224, the optimal twist rate is 1-9.5. Here is the link to the calculation. Good luck.
