[QUOTE="101stCurrahee, post: 1749620, member: 111731"] I just tested out my first loads in my Bergara HMR chambered in 300 win mag. I'm using H1000 and 215 Berger hybrids. I started at 72 and worked up to 78 grains in .5 grain increments, 3 rounds each. I was hoping to get some pressure signs, but don't think I got there. At 75.5 grains I had a slight ejector mark on one, but none one any others even at 78. For the most part they were all 1 MOA or below. Occasionally I got up to 2 MOA but most were good. At 77 grains I shot a <.4MOA group. at 77.5 and 78 they opened up huge to 2 MOA. I'm anxious to try out some 5 rounds groups here and see how repeatable this is. I'm wondering if I should even try .2 grains in either direction. I never expected to get below .5 MOA in this $900 stock rifle. My ES was 43 though, is that going to be an issue? Low was 2861 high was 2904. I'm trying to shoot out to a mile. The goal is to find a node with the highest FPS without being over pressured correct? Should I continue up above 78 grains since I didn't see any real signs of pressure, or is that stupid considering I'm pushing 2900 FPS and less than .4MOA already? Thanks [/QUOTE]
