A project.

I'm sure copper bullets are longer but dang I might have required a drop tube to really make it perform to acquire to even close to max load. Shots confirmed higher stress early on in a very rifle that typically likes the edge of max.

That is a wonderful question. A few months in the past, I shot one hundred rounds by way of 3 chronographs: the LabRadar, MagnetoSpeed, and Oehler 35p.

They weren’t off by more than a pair ft per next on Anyone studying. The LabRadar picked up about ninety five% on the shots, whilst the Magneto Velocity picked up 100% of the shots.

I believe I will follow my sixty six.40 grain IMR 7828SSC load and plug the temperature variances into the Utilized Ballistics app. That load is offering my a bit about 2900 fps and sub MOA teams. I assume that falls under the "if it ain't broke Never take care of it" category.
