Some of my cases also have the same type of ridge and not beveled . Are they still acceptable ? Using dies from copper creek and K&M trimmer . Just to add this is the 1st time I have done any bushing / necking down.
Thanks Tony
Yes the cutter does have an angle. Monday I will call K&M and order one with a 30 degree angle. I shouldn't of said 90 degees, it does angle cut but leaves a ridge line and doesn't flow or feather off back into the shoulder and you can feel it with your finger nail also visually. Maybe when they are fire formed it might go away .
I want to play with Ramshot Magnum a little, looks good. and will meter very well.
From the limited research I have done on Ramshot Magnum I know this: it will be a slightly dirtier powder, its a ball powder, pressure are a tad higher. I guess it will take someone testing it in a rifle to get real results. I'll test it if I can get my hands on some of it.

How's this for real testing??
Why the SL instead of EH stock? Just curious
SL is baddass that why!!
Lol, The SL is more comfortable and the way I have Tom fill it and the shell he does for this rifle its lighter and stronger.
Left handed guys can order the Xtreme hunter with an EH-3 stock.
While I do agree that on paper (Q/L) it looks promising and that the testing done so far is encouraging so much that I have a keg of it for testing myself but the consistency of it in different temps along with high count strings still leaves me with doubts. Only time will tell.Im thinking Ramshot Magnum is going to work real well!! 63 grains on the 140 and 65 on the 130 should be about perfect and keep pressure to 58,000 PSI

I dont think its going to be a big difference, Jeff Hoffman did alot of testing at Black hills on the ramshot powders and the Temp stability is good when compared to other ball powders.
Do you think there will be a big variance between winter and summer temps? Going to have to look for a solid alternative as H1000 seems to be dried up for the moment.
My reamer arrived from PTG today!!! I'm about 6 weeks away from a completed build now.
So. Freakin. Happy. Got my 6.5 SAUM from GAP today! Now all I need is some decent weather to go shooting. I'm thinking a mil/mil NF 2.5-10x42 for glass - opinions?

??? Not really sure why that pic posted upside down.
You were so excited, you had the camera upside down......grin!
Nice rifle!

Regardless, would be interested in hearing any thoughts on this as well (BDL vs Magazines feeding).
We have our own, Mag Box, Follower, and BDL type bottom metal just for WSM/SAUM its alot wider/longer than a Remington Setup. 3.015 OAL on the box. Its feeds like a dream. Ill post some picks up tomorrow of our Setup. Big #10 has this setup and its already sitting next to my desk.
That's definitely SEXY!!!!!
Advice please.
I have been shooting my Xtreme Hunter for a couple months now and love it. Now I have a chance to buy an Armalite AR10 in a 300 RSAUM, with the intention of rebarreling it for the 6.5 SAUM, and threading it for suppressed use. I assume the bolt face will be good to go, and that getting a new barrel reamed for the 6.5 SAUM 4S is doable. What are the chances that the loads I am using in the bolt gun (130 Gr. VLD's) will clear/feed from the stock Armalite mag? How long would the AR barrel need to be to perform well in this cartridge, and what twist rate should I be looking for? Are the lower pressures of this cartridge going to create a gas issue? Or am I trying to push a square peg through a round hole?
Not sure if what I can share can be called "advice" but here is what I have been able to gather:
1. The Armalite factory 300 SAUM "AR-10 (T) Ultra" uses proprietary parts made for the specific requirements of the AMU trials. Armalite will not sell these parts to anyone except owners who broke what came with their genuine factory Ultra Magnums.
2. The parts that are unique appear to be the bolt, extractor, barrel extension, barrel, gas block and gas tube
3. The current Armalite "Gen II" mags allow a COAL of 2.83 and the mag parts (ribs, follower, lips et al) appear to stack and feed SAUM (and likely 4S) rounds correctly if the COAL is respected
4. The bolt on an AR-10 requires about 19,500 psi to unlock, which the 4S load can amply supply. Therefore, what remain are timing (port location) and pressure (port size) tuning. Getting this right is key to reliable cycling. The Achilles heel of the Armalite AR-10 Ultra for the commercial market was that the gas port tuning needed to digest factory "magnum" loads made it somewhat of a one-trick pony. And 308 high BC pills are still not plentiful. An AR-10 tuned to run 4S loads can be configured to get around the first problem, and definitely will NOT have the same second problem.
5. Twist rate is more affected by the need to spin a specific weight pill to a specific RPM so it can stabilize in flight, not so much its operating system being gas or bolt.
6. In the Armalite Ultra, the factory 165gr ammo at 3,075 fps likely ran at over 61,000 psi. This was a lot more than the hottest 308Win which ran at 53,000 psi. Therefore, nearly 20% more gas volume AND gas pressure required not only a different gas block to tame the pressure, but also a gas port closer to the muzzle to lessen the total volume that goes down the gas tube to cycle the bolt. The 4S loads according to GAP being closer in pressure to 308 Win therefore will most likely NOT require the same techniques so needed to tame the Armalite Ultra and in so doing, painted it into the corner.
Therefore, stay tuned. My personal belief is that there may very well be gold in them hills, especially IF AR10 users embrace the benefits of the 4S and will actually pay for uppers that are tuned to make the round sing. My fingers are crossed.
Question: I have Nosler and Norma brass I'm loading up for my 6.5. I thought I read somewhere that Norma brass is softer and has thicker walls which would force me to reduce the overall charge weight. Can I stick with the 61gr of H1000 for the 140 berger and 63gr of H1000 for the 130 berger? Or will I have to lower the charge weight a couple grains?
You're good with 61 and 63. No worries.

I see it's a race to be the first with a Savage SSSS, I received a reamer too
Nice rifle...really like the T stock, is it the lighter weight, 90% carbon version?
