I'm wondering if pressure can be predicted for .223 from the following information: CZ527 carbine chambered in .223 Remington, fired and neck sized Sako brass, CCI 400 primer, Nosler Partition 60gr bullet seated to 2.20" OAL loading Winchester 748.

Reason I ask is data for 748 is not real easy to find. My best interpolation is 25-26 grains as max load with slightly lighter or heavier bullets. (55-64 grain bullets)
 
Lyman 49 lists 748 data for loads from 45grain bullets all the way up to 80grain bullets.

I shoot 60gr vmaxs which is a similar bullet (60gr jacketed flat base) so it'll be pretty close. Pm inbound.
 
Here it is. Good luck.
Code: 
Cartridge          : .223 Rem. (SAAMI)
Bullet             : .224, 60, Nosler Partition 16316
Useable Case Capaci: 25.320 grain H2O = 1.644 cm³
Cartridge O.A.L. L6: 2.200 inch = 55.88 mm
Barrel Length      : 24.0 inch = 609.6 mm
Powder             : Winchester 748

Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

Thanks. Is Sako brass and CCI primers a specific variable in quickload or do I need to verify water capacity?

Also would it be useful to know what quickload predicts with a known load with the only variable changed being the bullet? I have a 40gr varmint load for the same gun.

That's interesting.

According to my book Ithe load I shoot is closer to the minimum than the max, but according to that I'm near max. Goes to show the importance of multiple sources and starting low.

Edit. Checked another book and it had data that matches closer to that quickload page, I've forwarded it to you too.
