[QUOTE="Kevin Thomas, post: 690193, member: 15748"] Greyfox, I'll take your comment one step further, if I may; it's not that the slower burning powders won't function well in Garands (they will function just fine), but that they [U]will[/U] damage the gun. The gas system on these guns calls for relatively fast powders like 4895 or (at the slowest) 4064, ideally with bullets of not more than 175-180 grains. Slower powders, such as the 4350s or 4831s mentioned in previous posts WILL bend the op rod. Simply too much port pressure, which results in very violent cycling of the action, in turn resulting in parts breakage. This includes loads which are well under maximum pressures for the 30-06, and are perfectly "safe" by any other criteria. Op rods are getting harder to find these days, and ever so much more expensive, so it's not a mistake you can afford to repeat too often. [/QUOTE]
