Yesterday I took a 1903 that was given to me a few years ago to the range. I'd never shot it before and I don't believe it had been shot in over 40 years.
I brought some of my 180 55.5 IMR bullets that don't shoot well in my Weatherby. They've been loaded for a few years and were loaded with Winchester primers. After the shots when I ejected the brass the primers were flat and expanded. I grabbed one of my 165 55.5 IMR with CCI primers and they didn't flatten.
Is this just a Winchester primer issue or could I have been running into pressure issues with the 180 load?
Any insight is appreciated. Thanks.

Primer flatness is just about worthless as a pressure indicator. General Hatcher said this in his famous book over 60 years ago, and nothing has changed since.
If you want the reasons for this, I can supply 'em, but have grown awfully bored with doing so repeatedly over the years.

No need John. I don't reload nearly as much as many on here and just wanted to make sure I wasn't missing anything.
Thanks.

Was the bullet into the lands. Cycle one through the action then look for rifling marks. weatherbys have long magazines and throats.

The people wringing their hands over Trump's rhetoric don't know what time it is in America.

A number of yrs ago now Win primers were suddenly extra soft. I noticed flattened primers from the same loads used with previous Win primers that were fine. I know it wasn't long before Win again stiffened up their primers. Is it possible your loads were assembled useing those soft primers?

A few years back my neighbor gave me five hundred Winchester large rifle primers, he had them for quite a few years, they were in the white box with red letters. I worked up a load for my 284 with these primers, one day I accidently loaded up a box with this load with todays primers, blue box, sure enough the newer primers looked much flatter.
