G'day juststarting,
Can't agree, 44 is mid-point of the ADI listed loads for that combination of projectile and powder, all data is well below SAAMI to allow for variables in brass, primer ( a BIG factor in pressure variation!), rifle used etc. To take the mid point as a start is not unreasonable. Load development to find accuracy does require a starting point,usually at the lower end of listed data but the upper limit of where you go is determined by data and actual result. My current load using the same components as Hangfire is 47.2g, in a PH1200 action and Black Mountain barrel, I got there from 43.0 and ladder testing.
Hangfire,
Read marksman's post, twice. But understand that compression loads are not a good thing for mallet seating! Also, higher velocity does not mean better accuracy, your rifle may find a sweet spot at much lower speeds, so ladder testing, with a chronograph to help if possible, is the only way to work up. Cheers
PS: Being NATO spec brass, the water capacity is 46.0g compared to an average of mid-50's in most commercial brass.
