I looked at the Ten Point site FAQ, and there was a question about household products as a lube, specifically vaseline, and the answer was a definite NO. Said something about the lube getting into n area that could damage the string if I understood the official answer correctly. Also said lube the rail about every 75 shots which isn't nearly as often as I've read on the forums in the past. When in doubt check the manufactureres web site in FAQ.
