Anyone shooting these yet? My cousin bought a box of them to try out but he is having trouble finding any load data.

Just use one of the many loads for 175's..Work up

That's what I told him. But he's new to reloading and has nobody to ask for advice on the subject.

Lots of 7mm cartridges out there, any idea which one he is shooting? If vanilla 7mm Remington Magnum, hard to imagine Retumbo or H1000 not working.

Ah yes, he's shooting a rem mag.

I have a great load with IMR 7828 SSC and CCI 260 primers. Shoots really well the three times I have tried. Haven't chronoed the load yet. Would assume around 2850 give or take.

He is starting out with a very finicky bullet for sure. They have extremely thin and soft forward jackets and deform quite easily. I hope he doesn't get frustrated with this bullet. I think they are way to fragile myself.

Here is Nosler's load data for the 7mm Rem Mag

I have some 175's just haven't had time to work up a load but I have messed with the 168's and the 30cal 210's and found it fairly easy to get sub MOA groups. I would think the 175's should be no different.
