I have been chronographing my factory Hornady 147 gr loads out of a 24" proof CF barrel over the last two months. 8 total strings of fire collected, averaging 20 rounds each string (some more, some less). Avg Velocity is 2,708, Avg SD is 13, Avg ES is 53. That data is statistically relevant. So anything that good or better will make me happy. What I can guarantee will make me unhappy is weighing every charge. I have weighed thousands of charges on RCBS Chargemasters and for me, in my life right now, with the time I have available, the juice is not worth the squeeze. If I can't crank out these rounds on a progressive and get decent results using Staball, I am going to bite the bullet and buy factory ammo. I do like the idea of using some different bullets and mastering the Dillon which is why I'm considering this. It's all about enjoying the process so I should have mentioned that this is one of my major goals as well. Enjoying and not loathing it lol.
