| OK, here is the grand plan of attack. I've gleaned enough information to start laying out the money and time in testing. These are design goals, and they are lofty, so reality may not bear these thing ... |

| Thanks so much again, Bob. I won't pester you any more for graphing. That told me an awful lot. Not quite as rosy a picture as I'd hoped for, but such is engineering. The reason I was curious as to us ... |

| HPs won't alter the twist needed. If you look at high speed photos of a bullet in flight, the air isn't actually in contact with the nose. The turbulence across the ogive creates an air pocket that di ... |

That is just flippin' awesome! It's the coolest thing since sliced bread. Thank you so much. This will come in very useful and I won't forget you for it.

| I could use some critiquing on my math here. Before I start testing, I need to make sure I've got my head completely wrapped around the numbers for multi stage pumps. I realize the scenerio below may ... |

| The bearing surface has the largest impact on required twist. That's why the Border Barrels calculator has nose length as an input--so it knows how long the at caliber portion of the bullet is. Very i ... |

Much thanks again, Bob. You answered a number of questions without me having to ask. You truly are a gold mine.
The reason I'm not interested in the Condor and a pump is weight and bulk. If this w ... |
