I’m thinking your probably right Bare, I thought for sure they would have introduced the 7 RPM by now but being the .25” are vogue these days it makes more sense……I’m pretty sure it’s a 25 rpm. I seen a photo last week of a new 25 cal cartridge and it looked exactly like a 25rpm

.473 bolt face with that rebated rim. Think of it as a longer. 284 Win case.What does this RPM thing do that a WSM or SAUM won't do? And please don't say it uses less powder and delivers the same FPS....

Oh......473 bolt face with that rebated rim. Think of it as a longer. 284 Win case.
It feels like weatherby learned almost nothing from the win mag release. By starting with a 6.5 and 338. Instead of starting with the more popular 30 or 7mm bores.
Quietly looking for a used 338rpm thou. They are niche solution to a excellent bear rifle.
6.5-300bee suggests they don't care about such things lolthe 25 cal would be to overbore !jmo
YUP ! BUT not there most popular cartridge either !6.5-300bee suggests they don't care about such things lol
Nothing with a Weatherby head stamp is all that popular. Those who own them love them, but it's not like a Weatherby cartridge has ever been the most common option for a caliber.YUP ! BUT not there most popular cartridge either !
9.3RPM would be sweet!Im betting the new cartridge will be a 25 cal. New life on Roy's darling with a fast twist and heavier bullets.
However im personally hoping for a 35 or 36 or 40 cal myself. Wby doesn't offer those yet that I know of

Now a days it’s AdamOh.....
Well then...
Is it just for those that worship at the Alter of Roy?

You mean 300 PRC don’t youI ran a 300Wby until just this past summer.
Nothing spectacular, just a plain VG2 dumped into a B&C and added Accubrake by the orig owner.
MOA accuracy with OTC Hornady 200gr ELDX’s with tolerable recoil (30-06’ish)nwas a pleasant surprise. Ya it definitely had the thump behind it for the range I wanted, but certainly not cheap to feed (nothing is these days) with factory ammo. This led to it being sold off (jury is still out on that decision).
If I were to go the .300 route again, I’d probably end up with a straight 300WM, at least the difference in ammo cost would warrant it sticking around a bit longer than the 300Wby did. View attachment 1068093
Yup, those heavy bullets have me rethinking building another 257 STW. - danNothing with a Weatherby head stamp is all that popular. Those who own them love them, but it's not like a Weatherby cartridge has ever been the most common option for a caliber.
Interestingly, the one place Weatherby really does stand out amongst the crowd is the 257bee... maybe not the most common/ popular 25cal but the number of popular 25cal cartridges was pretty limited compared to 7 and 30cal. (I say was because it looks like we're getting a new wave of 25cals thanks to the new high BC bullets and who knows how that'll shake things up over the next few years)
