In my opinion (remember, it's free & you get what you pay for) you should be fine. However, Titegroup would not really be my first choice in powders. I'd lean toward a somewhat slower powder where the range between min & max is more than .5 gr. Some people's margin of error comes close to that.
I'd use HS-6 or Unique.
I would also recommend that you hunt down a Lyman 49th Edition Manual.
