The Hodgdon data you published is accurate. Since your bullet falls in the middle of those two weights, you should be fine with 3.0 to 3.8 grains of Titegroup, but should probably start at the low end and work your way up if you want a little more pop in the loads. 105 gr. is really light for .38 special bullets, so you won't have much in the way of recoil.
