I have the same dilemna, I recently aquired a 7 STW Laredo and have been scouring the country looking for long range hunting bullets.
I must say that I have a few buddies that already shoot long range 7's, (7 STW, 7MM Dakota, 7mm RM, 7 WBY Mag and 7mm-300), they have
played with bullets for a while and I have been picking their brains trying to decide which bullets I will be using for my STW.
In general most of the mainstream bullets will work but if ultimate long range ballistics are the priority only the highest BC bullets will do.
I will not be splitting hairs on which has the highest BC but will be looking for ultimate accuracy within 150 to 180 grain weights.
General feed back has been that the Berger Hunting bullets might or might not work in your rifle and if they do you must be careful with shot
placement because they really come apart upon impact even at very long range, even when compared to regular everyday non bonded
bullets like Sierra's and Ballistic Tips. I believe that a compromise should be made between penetration, accuracy and BC.
I for one will be trying the new Nosler LR Accubond in 150 and 168gr for accuracy since the Accubonds have performed very
well for me in a few different calibers and game, as much as I like the Bergers I am not comfortable with it's fragile construction.
