believe it or not I tumbled them for 3 hours.....maybe my media needs replacing
The projectiles are the same as what comes in the Sako factory copper ammunition, they were accurate enough however I couldn't get enough velocity out of them in the lightest 30 cal offering (162gn) to make them viable outside 300y which is a shame as I used the 140gn factory 7 mm rem mag version last roar and found it very good.
they would go well in a 300wsm or similar.

180 ELDM new ADG brass 64.5 gn RL26 @ 2880 fps from a 20” barrel
Testing gave ES of 5.1 and SD 2.1 group of 0.65
That’l do me 😎
I can just about get 3000fps with the 162eldm - my ballistic app shows the 180’s “over taking” the 162’s by 150m out to 500 shooting ever so slightly flatter and delivering 44% more energy and a lot less wind drift.
Was quite surprised at how much difference there is between the two.
Yeah and action length mine is based on a T3 set up with a long throat so COAL is 3.125” the Greg Dooley articles on the PRC in his magazine had the saami coal at 2.825”
I found a good article by Brian Litz on the benefits of this “In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve greater velocity at the same pressure than a cartridge with a bullet seated short.” “After all, when you seat the bullet out longer and leave more internal case volume for powder, your effectively making the cartridge into a bigger cartridge by increasing the size of the combustion chamber.”
My 7 saum is not far off a 7 prc with a 20” barrel velocity wise.
Gone to harder ADG brass from norma 300 saum necked down.
I think barrels make a difference too some just seem faster.
