I really like Nosler bullets but I am usually 100fps and usually closer to 200fps behind their numbers. I would love to have their magic barrels though.
Mine did it with 1x fired brass and my primer pockets were fine.
Winchester has never returned any call or email that I have sent their way about the primers I had.
If I'm going for steel or paper I load groups of 50 - 100 of a proven load. For hunting loads I only load groups of 20, that gives me a few to check zero with and then some to hunt with.
I have pulled the seater stem, chucked it in a drill, loaded a bullet with polishing compound and lapped them before with good results.
I have an RCBS set that wanted to pull every 220 Speer I loaded in my .358 win. A little time with some lapping compound cured it of it's evil ways.
I don't load 4350 in my /06's with 180's but that looks a bit high to me.
I have a PDF with the 180 PT with H4350, Lapua Brass, Fed 210.

You may shoot a lot so this may not apply to you, but practice a lot at ranges from 300-600yds if you are planning to shoot that far.
A friend who hunts knew I shoot longer ranges some and he wanted to try his hand at it. His guns are zeroed 1.5" high @100yds and both he brought are...
I've never hunted Utah but I use a 200yd zero on everything that isn't a lever gun and if it's something I shoot a lot then it has a scope with a turret on it so I can dial for distance.
