I am just going to hope it works at this point (and if not correct/make it work as I go) :D
The powder I am using is 3031, which is a suitable powder for this type of loading (my favourite for all sorts of milsurps from my Swiss 1889 to my 8mm Lebel), and I am not trying for too much velocity, aiming for roughly 2300-2400ft/sec (like the original loading). The case capacity of the 6.5x58 is 90% of 8mm Mausers case capacity and the loads in my book for 150 grn bullet in 8mm start at 49grns of 3031. 90% of 49 is 44grns, and I am starting at 40grns so it should be fairly safe (plus these actions were later on successfully converted to 8mm with no issues, so they are a strong enough action). I'll be sure to post the results.
