I don't know about the crosshairs, but the colored tracer with colored HE/AP shells will always work every patch for me though I have to always put the trails folder inside the particles folder every time a patch hits. I been using the Blue tracer with red shell for HE, Blue shell for AP for quite a few patches and it never breaks other mods or stop working completely. Hope Aslain would consider putting this into the already amazing modpack.
