Pretty much, the M2 is a beast and those moving parts are heavy. At the same time you dont need to max out the charge to make the gun run reliably.
Some of the M2 owners will post soon about what loads will work, 220 grs of powder should make any M2 run without any issues. 240 grs should be used as a MAX load but I know guys that have used more. Just comes down to being safe, seen one M2 get screwed up because the owner was using shitty old ammo. Another issue is saving money, by using less powder when reloading, you can load more rounds. |

Other than being old all my ammo is surplus LC or similar. I am not interested in saving a few cents in powder on a $30,000 plus gun. |

To echo 50_shooter I find 220g of WC860 runs my semiauto M2HB with API pull down bullets. I have also used 225g of IMR5010 with the same bullet and had zero problems.
Based on you $30k comment I assume you have a full auto. Running light loads can slow down the cyclic rate same as running tight head space. One trick I learned from the local MG shooters is to coat your rounds with a light coat of furniture wax. This will ease extraction and extends case life. Johnson's paste wax in the yellow can works well. Rub a little between your palms then roll a few rounds to give them a light coating. It dries to a none sticky solid and does not attract dirt/dust. PS, if you are looking for powder Bartlett reloaders has both WC860 & WC870 at a decent price. |

I've had good success with wc872 at 225gr for 647gr to 690gr bullets. US869 performs similarly.
wc860 or IMR5010 at 218gr - 220gr with the same projectiles. H50BMG performs similarly. For heavier 750-800gr bullets, published RL-50 or VV20N29 works well. |
