[QUOTE="elkaholic, post: 1837824, member: 13833"] I took some of the new fire formed ADG brass out today to get a feel for velocities and max loads. I fired 5 loads of N570 behind a 230 hybrid. I was having trouble getting readings at first so only got the 86 grain reading at 3080' and pressure was fine. I fired 87 and finally reached a bit of heavy bolt lift (no x marks) When I measured the web on the brass, it verified what I observed. 83-86 measured the exact same and the 87 grain load expanded an additional .0005". Velocity was probably at 3120'. I went back out with H1000 loaded from 82-85 grains. no reading at 82 but 83 was 3045'. 85 clocked 3140' and had heavy bolt lift and a slight x mark. 84 had some increased bolt lift also. I would say max with H1000 was at 3045' with the 83 gr load. I loaded 1 case with 87 grains of N570 behind a 215 based on my testing with the 230. It cranked out 3211' and bolt lift was nice and easy with no x marks. I think another grain would likely show the first signs of pressure and velocity would be 3250'. Pretty impressed with the brass and speeds so far![ATTACH=full]177201[/ATTACH][ATTACH=full]177202[/ATTACH][ATTACH=full]177203[/ATTACH][ATTACH=full]177204[/ATTACH] [/QUOTE]
