[QUOTE="Huntnful, post: 2297192, member: 116563"] With a precision built rifle, good optics AND mounting system, I think it's pretty simple to get 1/2 MOA fairly quickly. Just personal experience with MY rifle and 7 different bullets I developed loads for. Basically just for fun and boredom during the off season. All bullets easily shot 1/2 MOA with 20 ES 10SD or better. 195 EOL berger 180 Hybrid berger 180 VLD Hunt berger 180 VLD Target berger 177 Hammer Hunter 169 Hammer Hunter 143 Hammer Hunter All with N570 and 215M in either Peterson or ADG Do a charge weight ladder. 1g. at a time. Hit pressure signs. Ejector marks, but mostly bolt lift. Back off 1g. or even 1/2g. sometimes depending on sign. Seating depth test. Start at lands. Seat deeper 10 thou at a time until best group is reached. Normally close to the lands. Hammers needed zero adjustment. Berger's were more finicky but didn't take long to stack them on top of each other. My charge weights were all in whole or 1/2 numbers. It really is simple, if you keep it simple. I watch all Ryan Furman's videos also. Super good info. But if I have a bullet/load that goes to **** with .2gr powder difference or .01 seating depth change, I'm going to try and find something else. I stuck with the hammers because they don't go out of tune even remotely as fast as the bergers do in my 28NOS. [/QUOTE]
