I am finding this to be one of the most EDUCATIONAL threads in at least a decade on this forum. THANKS to those of you posting useful comments that are adding to my education!Thanks to those who are posting respectful threads asking about details, even though you (clearly) have some issues with the whole BIG BANG THEORY being posited here. Respectful negative discourse is a highly useful intellectual tool.
BUT I have also found that in the last five years or so, most threads get hijacked by kids, kooks, and cranks, and it is just not worth posting a SERIOUS gun thread any more. Accordingly, I have posted almost nothing for a number of years. How exceptionally refreshing to see a thread like this, albeit with naysayers and s**theads who should keep their ill-informed opinions to themselves.
I do feel like I am in the company of like-minded gun enthusiasts who are seriously interested in the "gee whiz" area of shooting, and by golly it is fabulous.
I just hope all the dickweeds and naysayers go away, keep their ignorance covered, and allow the genius of the OP to shine away unblemished, for those of us who are interested.
SO FOR THOSE OF YOU WHO WANT TO ARGUE WITH THE OP, CAN YOU PLEASE GO PLAY IN OFF TOPICS WHERE YOU AND THE DAISY RED RYDER GROUP PROPERLY BELONG? THANK YOU.

Pleased to meet you Doug.
I too, am thoroughly enjoying this thread.
Lapua brass kicks arse, it will hold a tight pocket under ^ pressure way better than domestic cases. In my experience.
Can't afford the brass $'s to hot-rod any cal. these days, unless it is built on a Lapua case .... the cost of modern living and all
.If/When the bolt gets heavy on lift, or, prominent ejector marks, or, substantial case head expansion, or, loose pockets start to happen with Lapua brass ..... you may indeed have just reached absolute max pressure.
Not a recommended practice for those who know not, or for those who observe not, or for those that think not, ... of what they are doing when they charge a case.
After 40 years of the odd "steamy" handload or two, have yet to experience lug/seat setback, even the well pounded M96 Swede has stayed as tight as ever.
Nope..
Hey Kevan I'm going to try something for your dilemma, I think we can make 375 Ruger from RWS 8X68 cases, the base (web) dia is only .010" smaller and the rim will be .022" smaller but with the big Ruger extractor it shouldn't be an issue. My kid has a 375 ruger and I will make up some loads and fireform them and we'll see how they come out. I might also do this with a stiff load made from a 300 WM case, might blow out just fine. It'll look a little funny but you could then load the snot out of it, and have an endless supply of cheap cases, which the RWS are not.
Brass forms flawlessly at about 75,000 PSI
Before I have to don my firesuit again, Yes I have done this before and it works, I used to turn the belts slightly on 300WM and fireform them to make 8X68 cases, well actually it was a cartridge I designed which was a 7mmX68 Imp. Rather than try and find 8X68 cases I made up 1/2 doz from 300 WM to start, they were short but actually worked out pretty good then I found a 100 RWS 8X68 cases and carried on.

Well put Doug!
this place has degenerated quite a bit over the past couple years especially. I too am learning from this thread and have no doubt as to what the results will be. The Op obviously knows the yield strength of 4140 heat treated steel is far beyond what the brass case will stand. There will be no damage whatsoever to the rifle other than some throat erosion unless a case lets go and then we get to see how the sako handles escaping gasses, not likely.

They handle gas quite well. Saw a 308 deprime itself once in an example of what happens when you substitute a Nosler Partition into a load developed for a Speer Hot Cor.
Ruger 375 cases from 300 wm- works great.

I have adjusted the powder accordingly and have some more test loads to try. I was mistaken with the 270 Speers, I do not have 2 or 3 boxes on the shelf, I have another 20 or 30 bullets period, and minimal RL 17 and none of either available in town.
I think this would be a good time to switch to 286 gnrs and RL19 both of which I have lots.
Hopefully the weather picks up and I can hit the range for some more load testing and chronograph time with the 9.3, the new .375H+H and blow some loads out the tube of my other .375H+H in preparation for Africa in about 6 weeks.

Okay, I'm ready for the range again with the big 9.3. I just got my WSS order and have some very nice Leupold rings and a new 2.5-8 Vari X 3 on it now, so hopefully it solves the scope issues I was having and I can get it on paper for groups as well as chronographing.
Is everybody happy with my optics and mount set up now? There was a lot of negative discussion about the Redfield scope (wasn't mine regardless) and the Millett ring/base set up.

I think the scope is ideal. Of course, now that you have it in hand some dink will come by and tell you that you should have bought a Leica or Swarovski.
Your right BUM but I don't care, I won't own a Swarovski they will not warranty their scopes on any caliber above 338 WM and it says so in their fine print. A buddy of mine found this out the hard way with his 416 Rem. On my hard working, need to be 100% reliable rifles, I use Zeiss. Hope the weather holds for the weekend and I can go wring out more loads and rifles.
Looks kinda like my old preGarcia 338Win I recently acquired and then installed the Redfield Rev 3-9x40 with "accu-range" reticule - in old style Sako rings. A better scope might have been nice but it shoots accurately and I'm happy with the combo.

Well it is our August long weekend in the Yukon and #1 son and #2 son have headed out for a "everything gonna catch hell" weekend and some bro bonding. I will try to get to the range and see if my new loads reach the lofty expectations my buddy set for the 9.3X300 Win. Hope the weather co-operates and I can do some chronoing.
I shall report back !!!!!!!!!!

You peddling all the 35's now Ted? Someone got a wicked steal on the Model 7!
Yep, the rifles, dies, brass and bullets, and someone is going to get a great deal on the 358 Norma Mag, too.
The 9.3s do it all! How does your brother like his? Did he try any of the reformed brass in it?

Back at the range yesterday, had to wait for 3 hrs until the trap boys finished their weekend shoot so it cut my time down a lot and I didn't get all my loads fired that I wanted to test. HOWEVER.....the 9.3-300 WM did get the 270 gr loads chrono'd with some interesting results. I got 3030 fps with no pressure and easy bolt lift, next grain up got 3005 fps with no pressure signs..HHMMMMMM........next grain up got 3028 fps with slight tension on bolt lift and just a very slight ejector mark, maybe. HHHMMMMMMMMMM. I have seen this before but usually in super overbore cases, not with a bore this big and really a moderate size case for bore. Working exclusively with RL 17. I was quite surprized by the 3 grain stall with this powder, I've only experienced it with the real slow stuff never with the 4350/RL 17 burn rate powders. Will be switching powders now but it really does look like 3100 fps is possible, in this rifle cartridge combo.
