Hi Greenie.
I have used not loaded CFE223 in RG brass as yet but have loaded it using FNB which is similar.
55 X-treme
26.5gn CFE223
56.6mm Over All Length
CCI 400 Small rifle Primers.
Out of a 14.5" barrel got the following velocities
2773, 2824, 2802, 2800, 2780, 2825, 2798, 2801, 2821.
A load of 25.5gn should be ok but check the primers.
You need to get a chrony.
I use one of these.
