The Apex 194 grain has the same BC as the 240 grain CEB. Notice the short ogive on the CEB. It's not a sleek bullet. You'd be able to drive the Apex way faster.

Don't use Berger's stability calculator for anything but burgers. Bergers don't have tips. Honestly, just don't use their calculator.
Use this one. https://jbmballistics.com/cgi-bin/jbmstab-5.1.cgi
Thank you.
Both JBM and Berger's calculators show the same results for the 1:7" twist with the 240gr CEB Lazer: SG 1.65

Go for it. Will be a learning experience one way or another for sure.
This has me thinking of getting a 1:6" twist barrel for my 300 RUM to try 180gr to 240gr mono's. And, see what it does with 250gr lead. At least 3,200 fps with 250gr would be great to try to get to.
I'm also curious to see how the CEB 240gr Lazer mono performs compared to the Berger 245gr and A-Tip 250gr at 1,000 yards and beyond.

You won't get to 3200 with a 250 or a 245 cup/core. Guys are struggling to get 2850 with a 300 RUM and that weight. Was just reading about struggles to get to 3000 FPS with the 230aTip. Good luck though!
Here's some real world numbers.
