[QUOTE="MNbogboy, post: 1115736, member: 18849"] I have had the same experience...rain/wet cartridges...all the signs; with heavy bolt lift and flattened primers....Same load before and after no signs...I have no means of pressure testing but it had me stumped...A theory was that steam pressure on the outside of the case (created by pressurizing the water) some how counter-acted the internal pressure?...I didn't know if it was imagined or not and had not heard of it before either. The signs at that time were scary at least and I have never had the guts to try to recreate it.....My chrono is permanently housed in a semi dry "box" but dark conditions associated with rain normally may have "scewed" results so I don't recall if there was a correlation or if I even had looked for any association. I could dig back through my records and maybe find the data/weather sheet but that was several years and maybe several thousand pages but that could take some time (probably four years ago cartridge was either .260 or .257 AI...but that is as much as I remember). I too have a home range and its only a 200 feet to my dry shop...I too test during all conditions but always take care now to keep my ammo free from rain/snow and water drops.... Good to see that I am not totally crazy!..and maybe others will chime in and we all can learn from this... Good shooting, Randy [/QUOTE]
