I hear a lot of .50 BMG guys use mobil 1 synthetic (light coat) for their case sizing lubricant. Can anyone shed light on whether this is a good idea or not?
Thanks |

Have used Mobil 1 10w30 for years on every firearm I own. Go to Birchwood-Casey's website and pull their specs on their synthetic gun lube, then go to Mobil 1 site and compare. Mobil 1 exceeds theirs in every category including flashpoint. Next, do the math on how much per ounce you would be paying for each........not a hard decision.
Ok, dunno if its good for case sizing, just sayin... |

Hes talking about a case sizing lube......No argument on using it as a firearms lube. Would it work to size cases? Sure Are there better choices? Yep. Asking for a powder/primer issues using motor oil if you don't clean your cases well after sizing? Big Yep |

Years ago guys use to use STP. (it had a high % of lanolin as I recall)  Messier than hell. fucked up two 223 die sets using that crap back in the day never used 50cal. but i would say stay away from anything other than sizing wax or something designed for reloading |

I use mobil 1 synthetic 5w-30 to size .223 and .308.
Is it the best lube? No. Does it work? Yes... Too much and you'll get lube dents. Not enough and you'll get a stuck case. I wear a nitrile glove on my left hand and lightly dip my index finger in the oil. I smear the oil on my middle finger and thumb and then smear it on the case as I put it in the shell holder. One light dip every 3-4 cases. Doesn't really smell to me and I tumble my cases after sizing anyway. |

This is what I'm using to size rifle cases now. http://s660.photobucket.com/albums/uu324/daclark1911/imperialwax001.jpg Just a little Imperial Wax smeared on the inside goes a long, long way. Lubing two hundred at a time by tumbling can for minute by hand. http://s660.photobucket.com/albums/uu324/daclark1911/imperialwax002.jpg I use a motorized version of that. I have a coffee can mounted to a 90-volt PM Motor with infinitely variable speed control. Used it for lubing and tumbling back in the day. Pic's to follow sometime today. |

Does it trim, deburr and chamfur as well? I got to get me one of these. What other calibers do they come in?

| I've used Valvoline Synthetic when I didn't have anything else. I poured a little into a gallon sized zip-lock and thew in a bunch of brass... it ended up to be too much lube, but I found that for every one lubed case, I could then follow with between 5-10 un-lubed cases. It works, but it's excessively messy, a true case lube like Dillon Case lube works better. |
| I’m using Castro Syntec 5W-30 on .223 cases. I just pour a little into the cap, dip my finger and coat the case. I only have to coat every fifth or sixth case. A little goes a long way. After I’m done resizing I just throw them back in the tumbler for 30 min. or so and it’s on to the next steps. I figure one quart of this stuff will last me at least a…………lifetime! I personally don’t think it’s messy at all. My 0.02¢. |
