[QUOTE="Engineering101, post: 1038597, member: 63138"] You are shooting some pretty high performance chamberings. I have had the problem you describe in a 26 Nosler (the king of overbore) which would only settle down with US869 and no solid copper (Barnes) bullets. I have read a couple of comments indicating that stick powder can cause pressure spikes in the really big overbore cases and the US869 can cure the problem.. In my 300 RUM, RL-33 is pretty well behaved. I'm using 97.0 grains behind a 210 Berger Hunting VLD. COAL is 3.805" which is about 0.005" off the lands. This load has done multiple 0.5" 3-shot groups at 200 yards. From what I can see RL-33 is pretty well behaved though it does appear to have moderate temp sensitivity but not near as much as RL-25 and RL-22 which uses a different technology and are thus so sensitive to temp variations as to be unusable - my opinion.
