Thanks Doug, just ordered some from them. I also looked at their 340 brass but found a better price at Sleeping Giant Brass for that. Sleeping Giant also has 6.5-300 once fired for $39.99 for 20.

I just discovered people are using 6.5-300 brass and fire forming it for their 7mm STW's. Anyone here doing this?

[TexWeatherby]

No, but fire forming can be a tricky process. A very precise load must be worked up to get it right (trial and error, starting low) and it's usually a good idea to lightly oil the cases before firing and anneal them after.

WOW, almost a 1/4 million views!!!!

Allot of brass can be found on GB right now as well, most of which you can go to a website and get same price/less fee's. Midway seems to be middle of the road on pricing that brass for 6.5-300 right now;

Are you serious about putting oil on brass before firing?

[Grouchy]

case lube maybe?

My buddy I go out west with uses a 7mm STW and says it's nearly impossible to find brass for it, he also said he uses 8mm brass to reload with but has a hard time finding those now. There's only one gun shop in our area that has loaded STW ammo but want way too much money for it. This is getting crazy. He's going to Newfoundland this fall on a moose hunt, wanted me to go too but no way I was spending $9500 for a moose hunt. Wife would have locked me out of the house for that one. I have 3 points for mule deer in Colorado and if I draw will most likely be going out alone this fall.

Mike... If there's a particular ammo/load/price range your looking for in the 7mm STW, let me know and I'll keep my eyes open for it in my area.

A VERY light, thin film, yes. That brass is reforming in the chamber and friction comes into play. When forming takes place in metal shops, dies are lubricated to last a long time (friction = wear + resistance). This is what I was taught, that it helps the case fill the chamber as much as the load can move it, right or wrong, that's my story and I'm sticking to it!  At least some agree (see below).

I was taught to Never leave any trace of oil or case lube on any brass. When firing takes place the lube doesn't allow the case walls to grip the chamber walls and allows the full force of the expanding gasses to to push rearward on the bolt face and could cause a change in head space. It seems to me that allowing any lubricant on the case walls would allow it to compress the bolt and after firing would allow the case to "spring" forward enough to lock the bolt making it difficult to open the bolt. When fireforming brass for my .250 AI, I seat a 120 gr bullet long so it engages the rifling and using a starting load of propellant I fire it in that manner, My 6.5X.280 AI just needs the neck reduced to 6.5 so no fireforming is required.

Maybe I don't know what I'm talking about but I've been reloading for over 50 years and that's the way I have always done it.

After going to Load Data and reading the entire article I see we are talking about two different methods of fireforming. I don't use the bulletless method and your are not referring to placing a bullet in the case but using some form of filler.

[TexWeatherby]

My impression has been that the "bulletless" method is sort of the standard way, but I don't really know if that's the case. No claim here to be an expert on this, far from it; just know things the way I have heard and been taught. That is certainly a valid point of the gasses exerting pressure on the case in all directions, especially rearward on the bolt as gas escapes through the case neck. Do the case walls expand tight to the chamber enough to drastically minimize pressure on the bolt by locking the case in place - I honestly don't know. I would think that cases wouldn't expand against the chamber wall excessively, as semi-auto rifles and pistols have to eject cases almost instantaneously after ignition and the case would have to shrink back really fast to allow cycling (just wondering here). Also important however, is that the brass has to "flow" against the chamber wall to reform. I bet Weatherby knows a lot about this and could offer us some info - I'm curious about it now.

[Dino82520]

Semi autos and as far as I know, fully autos do not open the action until the bullet has exited the barrel and chamber pressure has dropped. Do you remember the problem Remington had with their semi auto .17 HMR with the split cases and hot gasses injuring shooters because of the action cycling to quickly before the chamber pressure dropped to a safe level.

so, any more word on a nation rifle?
