Jim,
You need to write the book, "Hell, I was there, too!"
Put me down for a copy of the first edition!
Thanks,
Jimmy

three cartridges have really impressed me, 1) 7TCU, 2. 7X57 Mauser and 3) 280 Rem. What do they all have in common? .284 bores and bullets. For whatever reason I have never shot any 7MM/.284 that wasn't real accurate. Even that beat to you know what WWI relic 93 mauser. I've always been impressed with the high Ballistic Coefficients of the 7 MM bullets. One hits a .750, 175 grainer Most other cal's lucky to hit .450's or so. The bore size, lengths, BC's, just seem to hit a perfect balance.

Kind of like choosing smooth or chunky peanut butter!
In the hands of most run of the mill shooters , a 270 is a better choice than a 30-06, which I believe was the go to in the days of the 270s intro!
If you compare it to some of the later coming caliber choices,yes there are some that will do better with less recol,but not really better enough for the budget conscious shooter to run out and grab one!
Do I like 270 yes,do I like other calibers , yes I do,would I feel over gunned with a 270 no,there is no such thing as too dead when it comes to game!
It's an argument that will go on forever!
If guys are picking on the 270 hey are leaving the 30.06 alone I guess!
I like my 7-08 Encore pistol,but I don't dislike my 30-06 pistol!
I like my .270 custom shop Encore rifle barrel,but I don't dislike my .300 win mag or my 444 Marlin,or 375 HH barrels!
All have thier place in my hunting fields!
It's all a case of what you feel comfortable with!
Hell if we didn't have choices,what wold we discuss here!
Life would be boring as hell!

Can you use shortened .223 case for the 7 mm supermag in the contender? I'm aprehensive to take on another consumer of maximum brass. Would you have to change out the extractor?
Thanks,
Jimmy

Where is the little smiley face stirring a pot? 
Yep, I can definitely see by that argument that the .270 is a crap cartridge. Introduced in 1925, it should have just met it's untimely death a short time thereafter...
... ahhhhh But it didn't. 90 years later, it's still around, when many other "new" cartridges didn't even last a decade after their introduction. I wonder why? 
Point taken though. You hate .270 for no reason except that their are other cartridges you like more. It's not that .270 cases always split at the neck after only two firings, negating reloading feasabilty. Or that .270 bullets are hard to find. Or that nobody makes .270 brass anymore. Or that it's an expensive round to buy. Or that it's known to be inaccurate. Or that every .270 owner you have ever met is an arrogant jerk who thinks their chosen round is the best ever. Or...
To me, it makes no sense - To hate one, because there are others you prefer. But I guess that's one reason there are so many cartridges around (and we are still building wildcats!) We are just never satisfied, even with something that has proven itself over 9 decades. I'm guilty as well in that aspect, because I've been thinking of "new" cartridges, even though I have plenty that do the job just fine. Just something to think about.
All the best,
Glenn

My like (not love) of the .270 comes from first shooting a .30-06 as my first center-fire rifle "test" that a buddy was helping me with. It damn near nocked me out of my tree stand. But when I shot the .270 next, I discovered that it was much easier on my shoulder, and I could handle it better while on stand.
Had the 7mm-08 been available way back then, or had their been a .308 rifle in stock in that little backwoods country gunshop, ... it might have been a different story, as I'd usually choose a 7mm-08 or a .308 over my .270 these days. But back then... it was the caliber of choice for me and tons of others, and it was readily available. The store shelves were stocked well with .308, .270, and .30-06.
I think it has "earned" it's place in firearm history, and I don't think it's quite the time for it to retire just yet.
All the best,
Glenn

"you could", however you'd be "cutting off your nose to spite your face". The 223 has some taper, even in improved versions. When fired in a 7 SM chamber, it will stretch to become straight-wall. Second: You pissed away the rim head-spacing advantage. The only other choice is to use 5.6X50R european cases, keeping the Rim advantage. Those tend to be VERY hard to find this side of the Atlantic, and can be quite pricey.
Extractor: The rimless extractor will work for both rimmed and rimless. If you're going to strictly use 223's, it may help to swap them out. it will tend to "scratch cases", but we've already shared suggestions for minimizing this. Big caution: Case web don't like being forced to stretch to straight wall, sizing dies won't go down that far anyway. In reality, you'd be the dog chasing it's own tail.
If you're dead set on shooting the 7SM, stick with the Max brass. "can you" doesn't exactly mean "should you", Some things you "can", but in the totality of things you're better off leaving well alone.
If shooting the 7TCU, the european brass may help, but why bother if your 7TCU shoots better than you are capable of?
