Let me piggyback on what has been an interesting thread here if I may. Ramshot moved the target on me. I have an older Ramshot loading pamphlet. It lists a max load of TAC in 223 (not 5.56) pushing a 60 grain bullet at 26.7 grains and a starting load at 25.4. I split the difference and built some loads with 26 grains using Remington 7 1/2 primers. I haven't fired any yet. Today I was skimming TAC loads on the Ramshot download and it lists a max charge of TAC pushing a 60 grain bullet at 24.8. Similarly I built some loads using 50 grain bullets and those loads too are beyond current Ramshot max loads. My launch platform is a Remington SPS.
I spent a while looking at TAC loads on various forums and have found some that show my loads as OK and have found some that show my loads as over max. Any thoughts?
