[QUOTE="Wachsmann, post: 2738402, member: 10429"] Regardless of what we have we all want to take our best options to the woods when we go. But with what has happen over the last several years and the impacts it had on the supply chain at some point I got tired of always trying to find cases, right type of slow magnum burning powder, magnum primers, etc., etc., etc., to feed my 300 Rum. It left a really bad taste in my mouth so I started looking into how can I get a short action traditional cartridge to preform and how fare could I go with it. Not to mention I like to shoot a lot and tinker a lot with different bullets. What was the most abundant easiest to find ammo on the shelf during all of covid. I never once seen 308 win sold out. Also the 7mm-08 was a sleeper that did not get a lot of attention. So I picked up one of each. Then I went to town on the 308 trying to see what it could do. Anything from a 168 up to a 220 grain. For BC department I have about 3 boxes of ELDX 212's. I'm still not quite satisficed with the velocity and pressure that I got from CFE223. It gave me the best velocities but it was always right at the point I started to get ejector swipes and this is also where I seen some of the best group at and then through in a 80 plus degrees day and the load went completely south.
