I am a beginner at reloading, having only worked up 100 rounds total. I had some really good results with those initial rounds, but the more I read and learn, the more I realize how little I know!
A few discrepancies I've noticed and I'm not sure what to make of it.
Trim length for .270 Win 150 grain:
Hodgdon's reloading data says 2.530"
Nosler says 2.540"
Hornady says 2.539".
Does the trim length make a difference? I figure as long as my OAL is accurate (measuring base to bullet's ogive) and I am consistent with what I go with in terms of case trim length, it shouldn't matter??
MAX charge using H4350 for .270 Win 150 grain:
Hodgdon - 49.0
Nosler - 52.0
Hornady - 57.6
49.0 - 57.6 grains seems like a significant spread. I assume there is a variable I'm missing here to account for this difference? Again, I'm new to this, so I don't want to experiment with maxing my charge by relying on simply watching for signs of too much pressure on the case. I'll have to learn that part later with experience. Thanks!
