It was imported because it impressed TR when his rough rider boys were getting their as^ shot off*Munches popcorn and laughs* I do not know what the big hype is about the 0.284"/7MM. It's a bore diameter I could just never figure why it was ever imported from Europe to America. We had so much better calibers here. the best thing the 7X57 ever did was donate the case for the 257 Robert's and the 27 Shepard. Good Lord! Am I ever going to get hate on this one.. well chaos reins.. my job is over.. back to boxing up guns for shipment.
I've loaded for and shot a great many calibers & cartridges at distance. Within 300 yds, you won't notice a huge difference when talking medium game. When shots start getting on out farther, the wind is not your friend and can cause a miss or nonleathal wound. 180s out of my 300 wm was lightning fast killers but the couldn't begin to beat the wind like 180s out of a 7mm. Move up to 230s in the 300 then they will hang with 7mm 180s but recoil of the 230s will then require a much heavier rifle or much greater shooter skill to manage that recoil enough to make accurate shots. Bryan Litz has an article posted on line somewhere on this very subject matter comparing 30 cal to 7mm with these very same statements. I didn't have to hear it from Bryan to believe it as I have experienced it for myself.

You mentioned your 270wsm. I've had two, and I don't know if it's just me or what but they had the sharpest recoil of anything I've owned. My 300 wm weighed just a little less than the last 270 wsm and I preferred shooting it over the 270 wsm.P.S. my 9.25 twist 7mm Weatherby shooting 180s loses bc enough that the bc drops to .675 which is almost identical (like scary close) to a 270 wsm running 175 gr matrix and also right there with a 300 win running 215 Berger’s. Of those three the wsm hits back the hardest and the 300 will be the most comfortable. My 7mm right in between... personal observation.
It’s so much more about your other gear ie: glass, rangefinder and loading technique etc at that point that it boils down to smile factor when selecting one over the other.
Yeah, wasn’t mine, but it was loaded hot with 175 matrix and h1000...shot amazing, but... woohoo ‘twas sharp.You mentioned your 270wsm.

I am a fan of your cartridges and your work. That said I can’t recall the last time I saw N570 on a shelf. I’m sure I walked on by as the price was unacceptable. I wouldn’t chamber for the promises RL-26 makes either. Regrettably I’d sooner place my hopes on Unicorn poop as a propellant. So what can one expect from a more diverse array of powders?You need N570 to get 3000' with a 195.
Yes, both the Max and SM need fire forming and the SM will come with a 308 neck diameter.
They will shoot very accurately while forming, like an A.I. You could shoot saum ammo in the max
I have a 270x308 norma 30 degree reamer I will gladly sell youI agree the factory 1:10" twist barrels are decent, but are inadequate for the newer slugs out there.. if you go to some of the barrel manufacturers (bartlein, Hart, Kreiger, bergara, McGowne, and a couple others) they have 1:8" and 1:7" barrel twists available. also Berger and Barnes make slugs more Ballistically efficient.. Berger has 150, 160, 165, and 170 grain VLD's that are awesome. the 150 grain Barnes is too long for the 1:10" and awesome in a 1:8" twist. I have used them. the 140's from Berger work better in 1:8" twist barrels. I too own multiple 270's 2 wins and 2 WSM. I truly love ****ing off the 7MM cult. the 7MM cult refuses to see the 270 as anything but a ancient slug. I know how many 7MM have failed when my 270 did the job. so the 7MM cult can kiss vital parts of my anatomy. I am 50 years old and have never once ever seen a 7MM or 6.5MM that could out perform my 270 until the RUM and the STW. those two cartridges are just faster.. not better. in the late 1990's I built a gun/wildcat 270 off the 7R/M case. it had a bit less recoil than the 7MM R/M shot better and performed better than any 7R/M that I came across. it has a 1:8" twist from Hart. 0.625" muzzle and never failed to take down an Elk when the 7MM cult rifles did.
My other go to cartridges are my 300 W/M (1:8") and my 338 Win Mag with a 1:7" barrel. The 338 W/M tosses 300 Grain VLD's down range quite well and makes the 7MM and 6.5MM people look like ignoramuses. so why on God's green earth should I fall into the 6.5 MM and 7MM cult's way of thinking? I've looked at the 6.5 and 7 MM cartridges as if I did not own my 270's, 300's, 338's (W/M and Lapua). I still would have gone with the 338's, the 300's and the 270's..
you spoke of recoil. I have shot more than my share of 7 R/M's, they have such bad recoil. I have shot a few 7MM RUM's more recoil than anyone wanted to take. I have shot the 6.5X55, the 6.5-06 (okay this one thrilled me), then the 6.5 Creed (worked over 260 Rem), then the 6.5 Gren (cool AR cartridge), then we have the 6.5-284 you can have it.. I do not like it. I have given the 7MM's and the 6.5MM's their chance to change my mind.. they didn't.. pretty much end of story.
I was on powder valley this morning and N570 is available. Midway tooI'm guessing Hornady didn't release a 7mm PRC because the .284 class is flooded with chamberings...it would be doing nothing new that hasn't been done for decades. For a 7mm there is really no reason to go with a wildcat when there are so many factory offerings that can accomplish anything your heart desires. I know they aren't "cool and new" or have fancy names but they will get the job done just as well.
IF you want a wildcat 7mm I would look hard into a 7mm Hart or 7mm/300 Winny. They can accomplish everything without having to use non-existent N570.
Freddie J. I am a speed guy. Launch long high speed bullets. The bigger the bore the more powder is needed and the heavier the bullets. To equal a 7 a 30 needs much heavier bullets and much more powder. A 33 is magnified even more. Pick your poison and recoil threshold level.It was imported because it impressed TR when his rough rider boys were getting their as^ shot off
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
