Loaded up 130gr -150 gr (Nosler) for my .270 with the cases fully re-sized and trimmed to exactly the same length. (Federal)
When seating the bullets using a comparator on verniers I was getting a difference on the OAL.
The target OAL was 2.8100, I was finding that I was getting most of them bang on but every now and again I would get a OAL 2.8050 or 2.8150.
I know this might seem a little anal but it annoys me.
I use RCBS shell holder, Press and Dies, I have checked the press for ware on the leverage system but seems ok the shell holder seems fine to
The only thing I was wondering has anybody found issues with inconsistent ogive diameters or profile re Nosler heads, it’s the only thing I can think of at the moment but it’s difficult to measure.
Any opinions or theory’s welcome
