Weatherby/Norma - Remington - Hornady

How would you rank them as far as quality and longevity?

Just purchased a 300 Wby rifle and starting from scratch for components.

I've got a ton as well as dies, let me know what I can send you.

I already have RCBS dies
Thank you

Those mentioned I would pick Norma.

I think Weatherby is made by Norma.

I think I still have some Rem. if you want to try them yourself.

The worst brass I’ve ever used was a batch of Hornady .300 WBY. Starting loads resulted in smoked primer pockets. I’ve also used quite a bit of Weatherby and Remington and they’re both serviceable but the Remington did not holding up in the case necks as well. Most of this has been running a 200 gr Partition at ~3,030 fps which is stout but not Weatherby factory stout; the factory 200 gr partition load chrono’d around 3,070 fps out of my rifle(s)!

Peterson offers 300 Weatherby and may be worth trying out if you can find any.

Loose primer pockets are a condition that can arise from soft brass rather than excess pressure and cannot really be overcome, other than dropping the load back to the point where the pockets do not leak and primers seat firmly when reloading.
Of course this may result in 30.06 performance rather than 300 magnum performance.

On the other hand neck and or shoulder splits can easily be overcome with regular annealing, a relatively simple process to preserve and extend the life of brass.

RWS and Lapua brass have always been sort after for their quality and longevity properties, albeit erratic supplies, but I don't think 300 WBY brass is made by either brand.

Weatherby brass is made by Norma. These cases have more capacity than Rem Fed or other makes. Weigh your cases. For every 10 grs heavier your other brand cases are heavier than the Wby brass case capacity will be reduced by approx 1 gr of powder. So what is a max load in a Wby case will have excessive pressure in other brands of cases and your primer pockets will be loose in one or two firings.

Appreciate the information. Found a pretty good price and ordered 200 Norma cases. That should last me more than a few years.
