The 450 Primer Notion is funnier than fhuqk and Windowlickers can't ever speak in the first hand. 400's will arrange lower ES/SD's and I'm loathe to suffer 450's,until going 308 sized cases. Hint.
A sound rifle is paramount and there's much to be said for concentricity and pin clearance. Same Lot of ammo,in OEM guise and then with bushed/turned 'pin. Hint.
Though in "fairness",I've not opened a bushed/turned .378" Big Green bolt,in about 5 fhuqking minutes. I bush 22 PPC AFI 700's too. Hint.
Very few begin to have an inkling to "pressure" and they'll reliably fhuqking prove same obliviously. Hint.
Bless her heart for trying though.
Fhuqking LAUGHING!..............
