RE: Buffers for rifles
Compressed charges don't hurt a thing and may actually help accuracy at times. No negative affect though. Up to a certain point. As to bonded bullets taking up more space, it can't be because they are bonded if thats what you are inferring. It can only be relative to the bullets overall shape. Which is related to the weight and whether it has a boattail or not most of the time. WIthout looking and I could be wrong, but I'd bet that a 180 ballistic tip and a 180 accubond are the same size almost exactly.
YOu also have to realize that if you are not chronographing your loads you have no clue. Your loads may be 100-200 fps faster or slower than what you think. And factory loads are known to be a bit optomistic at times. OR they'll use a 26 inch test barrel when all the factory guns have 22 inch tubes etc....
Basically nothing new has been invented other than a combo of moly bullets and N500 powders could net you a gain of 100-150 fps max over whats considered normal. And in some rifles it may net nothing. Then you have to consider the chambers and throat lenghts, angles and designs. And what type of rifling is being used. All factor in to what you end up with on the front end.
