I was thinking about this earlier and wanted to see what the different opinions are on it.
Do you think Thompson will ever introduce the Pro Hunters(28") in the WSM Cals...Yes/No(If No, Why Not)?????

Nope, the WSM cartridges have too much pressure fore the Encore.When shortmags.org was up, there were a number of custom Encores that had issues with barrel pins, chambers, etc.
bulberry put out an accessory pin for them IIRC, but as far as I know, they will not produce them in factory configuration , at least not untill theyy revamp the rifle.

I just read an interview with the designer of the Encore/Pro Hunter and he said the exact same thing. I think it was in Rifle Shooter or something like that.
 
I thought it was because a lack of steel around the chamber, being fatter and all..........same with Ultra Mags

you dont want an Encore anyways, they are ugly
 
The 300 WSM cartridge has a 0.535" diameter and a 65,000 psi SAAMI pressure rating. The 300 Win Mag has a 0.532" diameter and a 64,000 psi SAAMI pressure rating. That is only a 2.7% increase in bolt thrust that the 300 WSM has over the 300 Win Mag. The difference lies in the length of the overall cartridge. The body length of the 300 WSM is 1.664" while on the 300 Win Mag its 2.196" or 32% more. The longer the body the more the cartridge grips the chamber resulting in less thrust on the action which consists of the lock up lugs and the hinge pin.

If it was dependent on wall thickness the stress would only be 13% higher on the 300 WSM. As a work around they could pick a material that has a 13% higher yield point which wouldn't be that hard to do.

Use all the numbers you want..this has been debated for years..Traps..it is the reasons already said. I had an Encore blow up in face so I do have some experience..

Hornady Reloading Manual shows the 300 WSM to be .555 down to .538 with a bearing length of 1.464 while the 300 Win Mag shows .532 at the belt but .513 just in front of the belt down to .490 with a bearing length of 1.976

Experience can count for a lot but it sometimes doesn't replace understanding. Understandably you had a bad experience and you probably feel partial to the subject but if anything it reinforces what Thompson Center says on the subject. Right from the horses mouth is an email recieved from Thompson Center to Eric on Alberta Outdoorsman:

Response from TC:


Dear Eric,

We don’t make any ultra mag or short mag barrels. It would be too much pressure for the frame..the head thrust would be to great. Have a nice day. Dianne, customer service

Subject: 300 Remington Ultra mag barrel



Hello, I have a question please. I would like to get an Encore Pro Hunter and a barrel chambered in 300 Remington Ultra Magnum. I see a few aftermarket companies that produce and chamber barrels in this chambering. But not many.

What is Thompson Centers opinion of chambering a barrel for 300 RUM and using the Encore frame?

Thanks for your time, I appreciate your help and I look forward to hearing from you.

Eric

Calculating bolt thrust is based off the part that is in contact with the bolt face or breech and is the diameter at the end of the cartridge - 300 WSM its 0.535" and the 300 win mag its 0.532". Calculating hoop stress of the barrel you would use the brass body of 0.555" and 0.513" respectively.

For simplicity I took the length from the shoulder to the cartridge head and neglected the belt.

Whats your point?..it is pressure..enough said. If I would have lived in the States..I would be really rich right now,for the injuries I received, thus no one wants the liabilty issues related to wsm's and ultra mags..

Its not pressure as they both have almost equivalent pressures of 64 & 65 ksi, it is the resultant head thrust and what that does to the lock up.

Sorry to hear about your injuries noneck.
 
95 percent of people on the site reload and know how to reload.. no skilled reloader wants others to believe it was his fault when he know it wasn't but can't prove it. just because he reloads his ammo does not imply he reloads unsafe pressures...which it seems to me your implying it is his fault.. head thrust is reduced by the length of the cartrige " sticking" to the wall of the chamber.. if noneck said it is unsafe and proved it at his expense i believe it wise if we all heed his advice...

Not implying anything, just asking a question.

Not trying to hurt anyones delicate feelings.
