Just wondering what you guys think is the reason they dont offer the 300RUM in the Pro Hunters? Is it a pressure issue? I see they offer it in 375 and 416. Is it a pressure issue or is it just because they havent offered it or what? What do you's Think???
Why No 300 RUM in Thompson Pro Hunters
- Thread starter wonksy
- Start date
WSM's are because of bolt thrust from the straight walled short case and its effects on accuracy. Talking to the master smith at TC he says some things just don't make sense when dealing with a rifle that is already much shorter than a bolt. To him short cartridges don't make sense in this case. I'm guessing they don't get much call for the RUM would be the reason for its exclusion.
strange, because from their custom shop you can get such straight walled cartridges like the 250/3000 Ackley, 257 Roberts Ackley, 280 Ackley, 308 Win Ackley, 30-06 Ackley. I notice they also will make a 416 rigby, which is a large diameter case........
Yep in the custom shop, there are a few caveats that come with a custom barrel that don't with a standard run barrel. 416 Rigby is a standard barrel, I have one. I wouldn't doubt the RCMs will be chambered in the Encores, there has always been a tight relationship between TC and Hornady. So other than claimed performance issues it could be political more than anything.
In the smaller Contender frames a straight case enables the Contender frame to safely handle hotter/higher pressure loads because pressures are distributed sideways rather than straight back onto the weak Contender frame.
A tapered cased round will direct more pressure to the frame resulting in a possible stretched frame.
If you check into the JDJ line of wildcat cartridges you will see that the cases are all very straight.
A larger rim diameter is also a bonus in the T/C frames, their are main 2 reasons for a larger rim one is for easier extraction the other is a larger rim diameter also displaces the rearward pressures over a larger area enabling the use of higher pressure rounds to be used.
My thoughts on the 300 RUM are due to the lighter weight of the Encores the recoil would be more than most could handle (unless they down load it) so they don't feel their would be a demand and it could create warranty issues with the 4 hole scope bases shearing the bases screws off.
If the barrel is a bull barrel then you could get a scope base and the barrel drilled and tapped for 2 more screws which would stop the screws from shearing.

It would be a good idea, seeing as how the Pro Hunters have 28" barrels. I bet you'd get great velocity and more efficiency when burning that huge RUM powder column in a 28" barrel to justify picking it over a .300 Weatherby.
No way...
I was just comenting that if the scope mounts/frames could handle the Rigby, the 300 UM would be no problem. Don't be a smartass.

For the same reason, there will be no 50 BMG in Cooey. Think safety margin. 375 mag .511dia case, is allready a stretch, in my opinion, never mind fatter case.

This all depends on what you are shooting these cartridges in. Light rifles with hard rubber or worse, steel buttplates(or narrow poorly designed stocks) in heavy recoiling cartridges hurt. Is there a difference in the design of the stock for the various calibers of the Thompson? I would hope that a rifle chambered in .416 Rigby wouldn't be just a factory barrel swap on the same rifle that would otherwise be a .270, etc.
I don't (or have any desire to) own any break action/single shot rifles.
