[QUOTE="deaddog, post: 805355, member: 45523"] I have a 6.5-284 and have been shooting sierra game kings with 42.5 grains of H4350 at a depth of 3.020..I have shot over 150 rounds at this recipe and never had a problem but at the range tonight i was doing a ladder test in seating depths. 3 shots at each of 3.010, 3.020 and 3.030. The 3.020 shot the best but my third round had an excessive amount of pressure. Enough to stick the bolt and enlarge the primer pocket. All the manuals i have seen say that 42.0 is starting and 45.5 is max so im way under max. The 3.020 is my pet load and never caused a problem does any one have any idea on what could of happened.
