I have been loading for the 7mm mag for over 30 years and I have not found a better combination than the 160gr. AB over a number of different powders.
That is some great marksmanship on those loads .
i too have been bitten this year by the 7 bug. picked up a remington 700 cdl new without the box never fired. put a burris veracity on it fed it it 68 grains of h1000 pushing 160 accubonds. its a joy to shoot and shoots extremely well. not sure of the fps as the chrony crapped out but can dial to a grand and ring steel. plus its a lefty
I've nothing to offer as far as an opinion on the 7mm mag as I've never owned one, but wow. Fantastic accuracy and shooting on the targets posted. Can't get better than that.
