260rem strange CBTO RDF vs Berger Hybrid

[usagi]

So I'm working up a load for Nosler RDF 140gr in my 260 rem. My previous load was 44.1gr 4831sc with a berger hybrid 140gr seated to 2.230 (30 thou jump). CBTO seems ballpark with what other people are seeing in the forum.

I gauged the RDF and they are 2.130 which seems strange. With 30 thou jump they seat quite deeply into the case. Is the RDF profile really that radically different from the berger hybrid that they would be expected to seat that deeply?

I seated the 130 gr. RDF @ .030 off the lands at 2.169 for my 260AI but have not loaded any 140 gr.

I’ll try to find my notes from my old 260
I seem to remember more bearing surface than the hybrid, looking like a shorter nosed VLD.

I ran the RDF at 2.304 for .030 off and the Berger 140VLDT at 2.325 for .010 off in my 260AI old barrel. I never shot the hybrids. The RDF were 2.980" coal at touch and the 140VLDT were 2.997" coal at touch.
