Remember that for the 300 Norma, I should buy the .590 version of Bolt Face. You mean there is little thickness left on the bolt walls that hug the case head?
What powder are you using?
Currently, in the 300win the 220gn ones come out at 2750/2800 max on one of my rifles. I don't think I can get to 3000ps which was the initial goal. I like the cartridge, and have several rifles on that chamber, but I wanted to try a new cartridge with a little more HP
good data about the action CZ magnum, but I want to keep the remy action that I currently have.
hell it makes "super efficient" wild cats have to run 80k PSI to get close 
!! which in turn is hammering on your action and you wont know it until your action is ruined!!
This you are proposing is a brand new rifle, and what I am looking for is to use what is available, as I mentioned at the beginning, buy a new barrel and go.
good arguments elk .... you made revive the Rum, they were winning the other options.parts list for me for a LR hunting RIG would be
BAT HR SINGLE SHOT
MANNERS EH1A CARBON
28" HELIX 6 hunter plus CARBON 1-9 TWIST
TT DIAMOND
ATLAS 5H BIPOD
The 300 RUM without a dought is the best available commercial/non commercial round made on a mag bolt face.
you get a 113 -115gr water capacity depending on brass!! what other cartridge does that on a mag bolt face?? That's why so many people hate it
There will and always be 300 RUM haters and that's fine, I like that! I personally will continue to reap the benefits of its larger factory case, factory ammo in droves, brass made from every manufacturer, no silly fire forming for no beneficial gain, brass life as good as any mentioned etc, etc, etc.!! Hell it was made in the late 90's and dudes are still trying to out do it and they just cant stand old tech whoopin em!!
When H1K @65-70K psi( my absolute favorite) is used it will be the king as well as any other powder you throw at it for that matter,, there is no replacement for displacement!!!! PERIOD!!! Remember one can run any case at extreme max and get good accuracy and scorching velocity 75K plus,, but most consistent and extreme low ES comes from a few grains below max!!
So this is where the large case cap comes in. You can lope along a 245 berger @3000fpsi with extreme accuracy low ES and repeatable ELR accuracy from day to day with no stress, where others are strained, using high nitroglycerine content powders! ha ha also when a speed claim comes with a max and then followed by ""But i wouldn't suggest running that"" be afraid LOL!!!
Can it be made in a wyatts CFE9 Of course and They work very very well and they feed spectacularly have for many years ... but in this case where your dedicating a rifle with an 1.250 straight tube 32" for a strict LR rig weight is your friend so add it on, that's why i suggested the single shot throating for the bullet to be outta the powder column and all that jazz! Oh and even when the bullet is in the case a little bit it will still outperform them when all variables are equal!
The 220 Hornadly ELD X sits above the neck shoulder junction @4.003" but i would suggest eyeing the new 245 Berger and the big sierra, when you start reaching sub sonic you'll see the benefit of the more streamlined berger/sierra. Trust me you can load a round pretty dam fast in a Single flipper if needed!!
Compare all rounds with same powder say H1K and you"ll see the clear winner! you cant throw TNT in one and a blasting cap in the other and call it a fair comparison!
All of the "more efficient coined rounds" seam to always have to run a double based powder to attain these "efficient" velocities and are dirtier than hooker on Fremont street! many a 300 rum, 338 edge, 338 ultra with 800 plus rounds of h1k never cleaned and still consistent low ES and scary accuracy out there!
How does the Sherman outperform the other 2 by 100+fps? How is the prc nearly identical to the 30 Nosler? Not sure what I'm missing, but I'd love to see the numbers to prove it when they are all throated properly.
RIGHT??? DAM!! i want some of that koolaid!!
Figure it out like everyone else!!
So, your answer is to build one of each, properly throated and compare? Is that how forums work? Is it wrong to question performance? Adding useful content as usual Bg
To each their own but i feel cleaning is a waste of time unless accuracy degrades.. if your burning dirty powder like VV RL IMR enduron etc. things change fast and will need adjusted.
