[QUOTE="swampratt, post: 2984431, member: 15054"] Oh yes a longer bearing surface can cause more pressure to build. If you have a Chrony you can test. For instance My cast bullets with gas check and lubed with LLA in my 30-06 will cruise along at 1400fps with 11.5gr red dot powder. You take a jacketed bullet with the same load and velocity is 100 fps less. The jacketed creates more pressure but results in less velocity. Now to really dump the can of worms out you can have 2 bullets with same bearing surface same length etc.. but one could be a very soft core and the other a hard core or a solid bullet.. The hard bullet will most likely create more pressure. (but not always) Now today the solid core bullets are of a much better design and alloy than 25+ years ago and you could actually have an alloy or guilding surface that actually will have less pressure than a jacketed lead cored bullet. Way too many variables to just say. This is it. I should be working on my truck. [/QUOTE]
