Original Optimal Barrel Time Paper

This has the list and two versions of the calculator. The excel one didn't work for me but the non excel version did.

This version is based on barrel time only so it is just one parameter. But somehow it can be an accurate prediction. Even better when used through Quick Load to determine which powders and charge weights get you there within pressure limits. I think this assumes a completely free floated barrel and it is still subject to field testing. It is just a mathematical prediction to get you approximately in the ball park.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
