[QUOTE="jpfrog, post: 1366817, member: 32525"] In my Remington 700 LR .300 win mag with a 26" 1:10 twist factory barrel, I was getting 1/2moa or better today. Base to tip measured 3.550" with Nosler brass, Fed 215, 78.8 grains of H1000 and the 180 grain Accubond. Avg velocity today was 2963 fps. It was about 71 degrees outside in Dallas, TX- not sure of elevation, but probably between 700-750ft above sea level. I was sitting in the shade on a bench shooting from a Caldwell lead sled. Chrono used was a Magneto Speed v3. No signs of pressure, and I can hear the powder in the case if I shake the loaded rounds. I'm sure I could load hotter, but after 79 grains the other day the groups started to open up, so I'm hesitant to do so. Part of me thinks I may even dial it back to 78.6 grains- that was showing slightly tighter groups than what I got today with 78.8 after I finished with the chrono and removed it from my barrel to shoot for groups. FWIW- the box for factory Nosler Trophy Grade 180 grain ammo lists 2950 fps at the muzzle, so this seems like a pretty comparable load if I ever find myself out of components or in a place where I cannot bring my own handloads.
