Dow55 is not recommended unless the gun was designed for it. Bob Long guns are designed to use Dow55. The reason is the Dow55 swells the orings slightly. In a macdev gun they can swell and cause bolt stick and other problems. Stick to Dow33 or a Dow33 based lube.
reason i'm asking is like all the ram orings i have are mostly too loose and a few too tight. i have one right now that leaks at really low pressure but seals when it reaches near full cycle cocking pressure. i'm assuming use a loose fitting oring with 55. reading thru the threads to help me fix my gat, i read one guy using dow55 on his 07 was running like 190hpr and 40lpr to achieve 290fps or something and another with an rx running hpr 170 and lpr flush for the same velocity. a few others posted sucess with it.
