If your load meets your accuracy expectations, then don't worry about it. Even a small amount of leading wouldn't bother me if'in accuracy doesn't go to pot after just a couple shots. Try some targets at longer range as well as some penetration/expansion tests.
Don't fret too much on published hardness values versus pressure. Way too much is made of it. Your bbl condition and boolit fit to the case, throat, and groove are not taken into consideration. Anytime I work up a load for a new boolit, I cast some air cooled, and some water dropped or OHT'd. The same loads are tried with both hardnesses. Often the results will pleasantly surprise you.
