Looking for some help, I’ve got a ruger m77 chambered in 7 Saum. I’ve loaded this rifle with Berger 180’s with success, but with the standard hinged mag I’m really limited on seating depth. So I picked up some 168gr nosler ablr’s. And I was hoping someone may have any advice on powders and or a good safe starting point. Thanks!

For what it’s worth, I’m jumping my 180’s .12 with excellent results so don’t feel you need to be tight to the lands
