Yeah I really wanted to try the RL-26 because of its success in your cartridges and others. I seen a couple good loads with RL-22 in the .308 Norma so I figure RL-23 should be able to match them but with better temp stability and consistency. If worse comes the worse than I will just order a few pounds of 26 and keep my fingers crossed that it works haha.
I am able to get about 71gr of RL-23 in the .308 Norma with a 208gr ELD seated at 3.550" OAL and the base of the bearing surface is at the base of the neck. This is not compressed but is very close to it. The Bertram brass I am using has less room in it compared to Norma. Not sure if I will be able to squeeze enough RL-26 in it to reach pressures but I am open to anything and I am pretty much paving the way with these newer powders in an older cartridge like the .308 Norma. It will be interesting to see how it does with modern propellants and a 28" barrel!
