I used Bullseye for several years to load all my pistol and rifle ammo. A couple of years ago Bullseye became very scarce in these parts and I purchased some Titegroup because it was what I could get at the time. I have found it to be very satisfactory and have continued to use it even when Bullseye became available again. I, like you, also load a .38 special using a 105 grain bullet. As to it being clean burning, I have not found any of the popular powders to be really clean especially loading low velocity ammo. I think if you will give Titegroup a try, you will like it.
