Well, Bushmaster, it was actually the sensors that I forgot, but with me fighting the flu and high fever, my mind wasn't working just right...
Anyhow, I got back to the range today. With this flu taking full hold of me, my wife was getting the insurance policies out when I left...

Now some of my personal observations. There were no signs of pressure in either caliber. When I loaded the 223 cases, the powder was below the case neck a tenth of an inch or so. My Win 748 load brings it up a little more. The can shows a load of 23.1 min to 24.6 max for 55 grain bullets. I think I am going to try bumping the load up a little and seeing what happens. It also shows 23.9 to 25.4 for 50 grain bullets. I just randomly picked the load figures as being mid range and went from there.
In 308, it seems like I am pretty close to where I want to be. The load data shows 42.5 to 45.0 for 150 grain bullets. Loads in both calibers looked to be shooting as clean as any others I have fired in these rifles, but I only shot 5 rounds of each load.
Neither load was shot for accuracy, just shot across the chrono into the berm. I am tied up the next couple of weekends, but will get some more loads ready and shoot across the chrono and for accuracy.
I am pleased so far. If the accuracy is good, I will be real pleased. At $52/8#, it can't hardly be beat.
