Campro 223 55gr chronograph velocity

[deadlydelta]

Hey,
Has anyone done a velocity test using campro 223 55gr bullets with CFE233 powder?
Im currently using 26.5 grs and 27.0grs CFE233 at 2.240
Just curious if anyone has a rought estimate on the velocity im getting using 0.5grs more powder and if its actually worth it?

Closest I got for you is 27.0grs CFE223 under a 65 grain Sierra BTSP did 2940 fps from my 20" Tikka CTR

I would expect a 0.5 grain charge weight to bring approx 50-65 fps change in velocity

Oh interesting, i have a tikka as well and i was guessing I was getting close to 3000fps.
Thank you so much more the information.

27.0gr with a campro 55 at 2.24OAL out of my 18.5” barrel produced and average of 3037fps on a chronograph.

3200fps more or less is typical for a 20" barrel and a max charge of CFE223.
