I've had enough faith in the partition that is if a certain weight bullet was called for or recommended, I could drop one weight & use a partition.

The same with a caliber recommendation. Certain caliber recommended for a critter, drop one & use a partition.

Elmer Keith recommending .333 & .338's to kill Elk was not so much his bullheadedness & thinking of the .40+ bores of the old days, but the poor bullet performance in the smaller bores at the time.

EK thought a 338 was needed due to the bullets of the time. Not the chambering.

The only reason I dislike quoting Schicks that his head swells that much MORE.

But: "bullets, not headstamps, matter"

Long story short, a 150 partition in a 7 mag. is a wonderful combo IMO. So, I have the love.
