Large vs small primers
#3
I went with the Lapua 220 russian brass and while I am pleased with this brass I am not saying it is substantially tougher than Hornady brass. The Lapua brass is substantially more consistent in my experience. and yes a bit more robust. My observation is case capacity looks to be near identical in my lot's of 220 Russian brass vs the Hornady 6 ARC case head stamping.


6.5 Grendel is another good choice in the lapua brass though I have not yet tried it as a parent brass for 6mm arc. My understanding is the Lapua 6.5 grendel parent is a bit easier or more so straight forward to form & may have slightly more case capacity.

Keep us posted on your results if you would.

Thank you!
