Best 7MM cartridge

From days gone by I got familiar with the 7mmRM and like it's performance. Although the 7mm08 is fun to shot too. If i was to expand on those two cartridges I'd favor the 280 AI.
 
I chose the classic.

Perhaps some old school stuff. Picture taken for another purpose a few weeks ago - I thought CGN might want to see - 7x57 case on left - I have taken many dozen head of deer with that one since year 2000 or 2001. Centre is 7x61 S&H - I think that was Phill Sharpe's development for his idea of ultimate North American hunting cartridge - I read it was the "push" for Remington to develop it's 7 mm Rem Mag - most European rifles had 26" barrels, I think Remington mostly used 24" barrels - about no one then had chronographs, so there was probably not much actual difference from shooting table? On right is my latest - so, a "wildcat" - 300 Weatherby necked down to 7mm - so MUCH longer than 7mm Weatherby - I have never fired it yet - I understand one can use Start level 7 mm STW data to get going on this one. The rifle is my first ever Remington 700 action. The barrel is circa 28" long, "stainless steel" - not blued or coloured - with a machined / integral helical "brake". I have not fired it yet - I did pick up some H1000 powder and some 160 grain Nosler Accubond bullets, to start with that boomer.

I ran a 7mm-300 Wby for a while. Once I built a 7 STW, I sold the bee, but ballistically they were almost twins, aside from the Wby freebore. - dan
 
Ok, you've talked me into 7mm. :)

I'm convinced I'm building a 7mm Practical on a Winchester 70 classic action in M24-40 contour. I don't hear a lot of talk about that chambering in Canada, but if you know a gunsmith with a reamer for that, let me know please.

You should post this in the Gunsmithing section.
 
I’ll play. Years ago I was trying to decide on which 7 I could build that would shoot a 180 over 3000 without being stupidly over bore e and have a reasonable barrel life with no belt. Decided on a 7 LRM. Long necks pushing a 180 Berger at almost 3100 fps. What’s not to like.

Just wondering 🤷🏼‍♂️ why you would pass up on the 7 PRC ? RJ
 
Only one I’ve owned was a 28 Nosler… don’t currently have one but have picked up a couple of boxes of 7mm bullets when I found good deals lately so perhaps I’m headed towards one again.
Given the choice I’d go with 7mm Wby Mag.
If nothing else, for the novelty. I’m pretty indifferent to all of the ballistic hair-splitting one hears.
