For wind, BC wins out rather quickly. Lets take the 6.5cm and 2 rather common bullets. The 120 Nosler BT at 3000fps and the 142ALBR at...

Doesn't Berger just use QL and publish it as their load data?

Use the total length of the bullet with the tip, and then enter the tip length in that part of the calculator.

If you have the length without the tip you could discount it in the stability calc. The tip is included because a plastic tip does not...

Berger's stability calculator does not factor in plastic tips. It's not useful for stability of anything with a tip.

What are you even using to measure such small volumes?

Interesting. We're talking some very small volumes/weights here. Just the meniscus would drastically change a volume measurement this...

Are they both 6cm necked down or just the Hornady?

^^^ True for load development, but what if you're just trying to get some idea of which brass is thick and which brass is thin so that...

Ya, this. If they sold 1 piece of brass and shipping was free, I'd go fire-form and measure. Lot's cheaper just to ask some people...

What's your COAL and internal case volume?

I generally get chambered pre-fits. I think the most I've spent on a barrel is like $600. Spin them on myself. Always stainless. If I...
