7mm Nosler 150gr BT bullets?

[akhunter]

I picked up a box of these to reload for my 7mm WSM. I usually use the 140gr TTSX bullets for hunting but have heard and read good things about this pill. My plan is try one on a spring black bear and then for sheep come August. Maybe on a bull caribou as well.

Anyone have any loads that worked well for them in this combo? Accuracy? Velocity?

The 150 gr BT should serve you well.

Fotis, thanks for that! Lots of good info there. Some good speeds listed with a variety of powders. Will post my results after I get to the range this weekend.

A 150 BT should crank in a 7WSM..

Anytime,
Take your time. Start low and work up slow. I am sure you will find the sweet spot. For my 7mm rem mags 7828 always worked at 3150 fps and 1.5" groups at 200 meters were easily achievable.

that's the velocity and accuracy i get with mine and 150 sciroccos using 68 gr. imr7828.

i want to try the BT myself as they work awesome on deer in the 120 gr 6.5mm out my wife's 260 rem.
