using bac water is fine, assuming its truely sterile.
hey bro try this trick i do with tt 100mg winny.
i assume your shooting oil in your cycle as well. do ed inj and just mix in a little oil. draw the oil first, then the winny into the syringe. shake the hell outa the winny first, i mean really shake it good. i draw using a 23 and shoot w/ a 25. it goes very easily, in and out. warm it before you shoot, and mix the oil and winny until its 1 color.
if it clogs while drawing, push a small amount back in and then redraw, this will unclog it.
if it clogs while shooting, pull back like your aspirating, it will unclog.
but most of the time if you follow those steps you should be able to draw and shoot very easily.
