I loaded up 50 pcs of 7.5x55 Swiss. My load workup from last november had me testing 4064 at 40.5, 40.8, 41.0, 41.3, 41.5. There was no pressure signs on any of these (as expected, Hornady max load is 43.2). I settled on the 41 grain load because it grouped nicely at 200 and it kicks significantly less. When ejecting the brass it's barely warm.
I'll decap and label the brass later after lunch.
I also played around with the new Norma brass and Swiss P bullets I got from Raven Rocks Precision. I found the maximum overall length I can load those is exactly the same as the Amax and Hornady HPBT bullets, but they're shorter projectiles overall so there's more room for powder. Going to have to work up a load again to use those.
