I have killed two bull elk with the 7 Mag, 140g Nosler ballistic tip at a MV of 3250 fps, countless deer. 150g Nosler ballistic tips at 3150-3250 in 9Twist barrels are incredible killers. Here in the South, we get to kill a lot of deer, if the bullets are bad, we find out in a hurry. I don't shoot deer at distances less than 50 yards as a rule, but I did kill my largest buck in Alabama with a 270 A Bolt with 130g Nosler ballistic tips as I grunted and rattled him up during the rut at a distance of 10 yards.
IN my and brother's 7 Stw's, we shot the 140g Nosler combined technology bullet at 3550-3700(28"-11T, .020 Freebore) depending on the barrel, and the 120g Nosler ballistic tips at 3850 fps with such accuracy few can believe the small groups with IMR 7828 and R#22. My brother's tire store has 4 walls full of trophy deer shot from all over the country, all with the 140g Nosler Combined Technology bullets.
We have no control over manufacturing standards. I begin to wonder if alloy that Nosler draws the jackets from or possibly the lead core hardness can vary.
A couple of guys shot the 7 Mashburn Super with the 150g Nosler ballistic tips at 3350, killing elk.
