What triggered the velocity difference? My guess is that the flat base bullets seated to the lands prompted higher force than the boattail bullets jumping about 0.010 inch. Each bullets weighed sixty five grains, however the flat foundation had an extended bearing surface area.
five. Inspect the circumstances, and set aside any with an obvious balloon to at least one aspect of the situation or banana shape for practice.

The longitudally-perforated or multi-perforated cylinders Employed in massive, extended-barreled rifles or cannon are "progressive-burning;" the burning area will increase as The within diameter of the holes enlarges, providing sustained burning and a protracted, continual push about the projectile to produce greater velocity with no expanding the peak stress unduly. Progressive-burning powder compensates fairly for the tension drop given that the projectile moves down the bore and enhances the quantity driving it.)
Time doesn't stand nonetheless and neither does the IMR model.
