[QUOTE="longrangehunterII, post: 785237, member: 61185"] I've had first hand knowledge of what can happen with hot loads developed at 203' above sea level and then fired at 6,000'-13,000' on a warm hot day..... blown primers! More then once I might add, but those weren't loads I developed, made me realize not to hot rod a round just for the sake of turning heads while out hunting. I just have to scratch my head when I hear a guy say his 6.5/300 WSM is running 3400 fps and I'm shooting the same cartridge and I clocked my own load using the same powder, same wight bullet and I'm fine shooting a 140 grain bullet at 3150-3200 fps. Seems odd, maybe I'm just too cautious? I also stated that I have tuned guns using bullets that were deeply seated and couldn't reach the rifling. But my point was it can be easier when you at least have the option of working up a load that's within 0.00"-.070" of then lands fed from the magazine and don't have to use a bullet seated below the neck shoulder junction. Compressed loads are and have been widely used over many decades, and are actually a better choice then a powder the doesn't fill the case as much in my opinion. But that's not what I was trying to address. It was a study about the internal ballistics with regards to the relationship of bullets being so deeply seated in a case, and the ease of tuning that load when they aren't. I'm certainly not the first person to address this issue, but common wisdom as been what actually happens inside a case with regards to the gases developed during the burning of the powder, and the effects that take place to push a bullet from the case? I was attempting to show the effects of seating depth to the lands, choosing a bullet that doesn't encroach completely into the body of the case, and the length of time developing a load? [/QUOTE]
