Thread: Too fast and dangerous? 7mm Rem Mag, 180gr ELD-M, RL26

I have only tested over the chrono, no long range validation yet as I wanted to talk to this group first before taking the development any further.
If I could get my hands on another chronograph to validate the speed the would probably help, but as you say a drop test would prob be the best way to confirm.

Greetings Kiwiazonic,
That's a nice rig. A couple of things to consider in your deliberations. First fast barrels give more velocity because they develop more pressure. Second you are working up your load in mid winter. I don't know how temperature sensitive R26 is but the pressure you get on a mid summer day in the Kaweka's could be considerably higher. Perhaps a bit of testing in hot weather may be wise before you load too many.
