I looked at my Grendel brass sized to 6mm ARC. With my nekkid eyeball I can't see a bump or bulge. But, with a 10X loupe, there is a barely perceptible bump at the body/shoulder junction. It can be felt more than it can be seen.
It's too late to fireform most of my brass now. I've loaded 5 different ladders already (150 rounds). I have 50 cases I've not loaded yet. What powder do you use to fireforming with your 55 grainers?
The only other time I repurposed any brass was when I changed some 30-06 to 8mm Mauser for a 98K that had a pristine barrel. At the gunshop where I bought it, they only had berdan primed, corrosive Turkish military issue ammo. I didn't want to shoot that nasty stuff in that pretty barrel so I bought a die set & 8mm bullets. I already had the '06 brass & suitable powders. I would have never thought about brass flow when downsizing cases if you didn't bring it to my attention. Even at my advanced age, I can still learn something new. Thanks...
