Looks like you're getting there, the barrel needs more rounds down the tube tho likely, and you can tune those loads a bit working up in .5gr or even .3gr increments. Trigger pull weight should be tested with a steady pull, you're not testing function of the trigger group to get it to fire, just the pull weight.

Just be aware that when you get below 3-3½lbs, you
may have problems with in not firing consistently, the lower you go, the more risk, and the pull weight will lighten over time, another reason to not go too low.
