It works fine with the 55gr also just not the optimum for top velocity that is available.The Sierra Manual shows it as an accuracy load in a couple of bullet weights.

Anyone using it for 223? I can get at least 1 8 pounder maybe 2 for a song. Is it worth getting or not?
Does anybody have any good starting loads for it? I will probably use 55 grain V-max pills.

I use Re 7 In my .223. Try 21.0 to 23.5g In the 55 grain area. I've had excellent results. Refer to a good reloading manual first. My loads may not be OK for your firearm.
I use RL7 for the 40 grain pills in 223. I also use it(a bunch) for my 45-70. Try it, you will like it. If you do not buy it then pass the deal along. Tom.
There are many powders that shoot well in 223's, RL-7 being one of them.
Benchmark, H-4895, TAC, IMR-4198, H-335, H-322, and RL-7 are good.
Testing in your rifle will establish which is best for you.
