[QUOTE="Hand Skills, post: 2500707, member: 103303"] I think a lot of it has to do with quality slower burning powers becoming available. Heavy bullets will increase pressure faster than a lighter bullet, yes, but a slower powder compensates for that with heavier bullets, slowing down how fast the pressure builds. Friction in the bore is a separate issue, and has more to do with 'bearing surface'. The .270 cal 170gr berger actually has a very short bearing surface, compared to a woodleigh 180gr for instance. 'Form factor' is an interesting concept, and may help in understanding the Weight/Diameter/BC trifecta; [URL unfurl="true"]https://bergerbullets.com/form-factors-a-useful-analysis-tool/[/URL] [/QUOTE]
