Yes by comparing cherries to apples you can get 20 or more grains diff BUT that ain't normal.
From Nosler # 7 manual
7 RM - 160 gr bullet Mag Pro -- 72 grs Max load
300 W 180 gr bullet IMR 7828 - 70 grs Max load

I’ve loaded for both a lot and for a long time. it just depends on what bullets you’re using and what powder and gun. For years a 160 nosler partition with IMR or H 4831 was 62 to 65 grs depending on the gun. At the time I was shooting 83.5 grs of h1000 out of a 300 fed 215 m and 180 sbt and you could run 80 with 200s by the book Talk about cherry-picking. I believe I said about but you want to cut me over a grain or two GFY. And just in case you can’t figure it out for yourself it was said with humor.
