Thread: Loading Sako A7 mm REM Mag using AR2217 powder

That's exactly the set up I'm using at the moment. A7, 7mmRM, 162 ELD-X, 2217, federal brass, but CCI 250 primers.

Its interesting you have a similar situation to me with speed variance as well. I'm about to narrow it down and I'm pretty sure it's the internal volume of the federal brass. The reason I say this is that with equal charge weights in the federal cases, when seating projectiles, some are compressed and others aren't and I'm getting a significant speed boost in the roinds that are slightly compressed.
