I loaded a box of .308 Win with 180 gr ballistic tips and RL15.5 and I like it. FC brass, Fed 210 primers, 45.0 gr of RL15.5. Did not chrono. A couple rifles went .5 MOA for 3 shots. A couple other rifles were in the 1 MOA neighborhood. I also shot 180 gr coated accubonds and they shot well. Only issue is that 45.0 gr is pretty full in a FC case, up to case neck.
