These days, I’m trying to wrap my head around the «dynamic fit»- concept.
The NOE 266-140 (se below) is the 6,5- bullet I have shot the most. I quickly got 1,5-2 MOA 5- shot groups, but haven’t really progressed much from there. So, I tried to analyze some of its characteristics:
1) Very long and slender; «flying pencil»
2) Very long, conical nose with good self-aligning properties
3) Long bearing surface, with few relief grooves
4) Very hard alloy, Lee says BHN27
—> Probably it would benefit from a «flying start» at the lands to facilitate engraving, without base distortion.
I shot a couple of groups today, were I gave it about 0.04in jump. This COL was chosen, cause it hid the lube groove in the neck, solving another problem. I only shot a couple of groups, as other projects were already planned. But it looks promising, I’ll follow this lead further with this bullet.
