Best 7MM cartridge

7 mauser. Had a few of the others. Because larger game can get a few other magnums, 300wm, 338wm, 308nm, etc, the mauser does what it's best at. A nice walking gun that's mild and light, while pushing a nice range of bullet weight. From about 100gr to 160gr, varmits to moose. Most projectile smaller than 100gr are too explosive/varmit, while larger than 160gr are going too slow, for anything but close range.

-I like that I can use 300 win mag brass.
-I like that it's different (uncommon)
-I like that I have an action that previously held a 300 win mag, so feeding from the magazine and the unmodified bolt face for another case head will be simpler.

Years ago I too was gonna have a 7 Practical built after I Read all Fosters info but decided to get a 7 x 300 WBee built instead !
Lots of 300 WBee brass available and feeds then same as the 300. .Carry on with your 7 Practical - Good cartridge .😉
One thing that I LIKE more better with a Weatherby then 300 Win or any cartridges based off it is the neck lenght is a lot longer on a WBee .👍 All the WB cartridges have long neck lengths . JMO RJ

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.

If you do that consider changing the magazne or modifying it to full length, and changing the ejector and shortening the bolt-stop to get it all to magnum length. The 7-300 and by extention the 7 Practical are happier it the magnum length action especially with VLT style bullets. So are all the standard length magnums for that matter.

I use the same loads and get the same velocities as Nathan in the straight 7-300 Win as he does in the Practical, with no firing forming and no custom dies. About all thats left is less case trimming with his steeper shoulder.
 
Your 7-300 Win Mag: what shoulder angle does it have? What dies do you use?

Also, I would imagine a model 70 in 300 win mag would already have the full mag length and bolt stop allow for the full magnum length, or is that not the case?

7mm Practical and 7-300 WM are intriguing to me, utilizing the full length of a standard magnum, and (apparently) with a little better barrel life than the STW or RUM, or 28 Nosler.

I gotta have one. Lol.

My 7-300 Win has a 25 degree shoulder, same as the 300. I just use my 300 Win Mag bushing die with the appropriate bushing because I already had it, and a 7Rem seater. For fun I’ve also used a 7 Rem FL die to do the initial neck down, and that works well enough too just to get shooting, and I’ve also used a universal 7 mm neck die. A 300 Win FL die with the expanding assembly taken out makes a functional body die and likewise my SB die does the same. That would probably matter more if I didn’t already have both body dies anyway. Its like there isn’t a wrong way to do it, and since I already had all this stuff it didn’t cost anything. I actually do pretty much the same thing with my 6.5-300 Win, but I digress.😂 Have you priced out 7 Practical dies? Last time I looked there was just Lee and they cost about the same as a good barrel blank.

The M70 has a spacer in the mag box on the standard length cartridges, which as much as I like M70s is still dumb. Fixable but dumb, from a handloader’s point of view.
I guess I’m just saying is the 7-300 is mire practical than the Practical. Probably didn’t hurt that my buddy had a reamer either.
 
I’ve had a bunch of moderate 7mm rifles, over the years, 708, 280, 7x57, 7x57R, 7x64, 7x65R, and the 7mm rem mag,
Shot several hundred deer pigs,Thar,etc with the 7x57, and a dozen or two more with the 708, few with the rest,
The 7x57 is my favourite, easy to shoot well, and just seams to get the job done, with out any fuss,
and I like the 7x64/65 as well,
Currently got a chopped and suppressed 18” Finnlight in NZ in 708, for my bush rifle,
M70 7x57 for more open country.
Combo 20ga/ 7x57R,
And here in Canada a K95 in 7x65R.

Running a can is so civilized; its hard to believe that the powers that be have decided we can’t have them. I think they watch too much TV.

It would be great not to damage ones hearing, not disturb other people, not disturb wildlife, etc.

Logic has no place in Canadian laws.
 
It depends entirely on what magazine box you have in there. My 7mm RM can take up to 3.6 OAL.

Not to mention recoil reduction. There aren’t a lot of downsides, bulk and weight being the main ones. Barrel heat and heavy carbon fouling are real enough; but shouldn’t matter much to most people.

Yep, 20-25 odd percent less noise, maybe more on lower volume smaller cartridges, generally found no loss of accuracy, and in most cases better, shorter stiffer barrel,
the half dozen moderators/ suppresses, I have, are all over barrel. Except for rimfire, Approx half the length of suppressor on the barrel, with barrel cut back, balance is pretty much the same, mine are relatively light 300-400g.
To be honest, I am surprised the safety side, noise reduction, Health etc. hasn’t dragged the government, into accepting them, no real problem is the places, that have them, and Europe/. England have much stricter regulations around firearms.

The only suppressor I’ve owned also fit over the barrel which helped some. I had it on my 7-300. Bought it in New Zealand, about 500 bucks with over-night installation. Accuracy didn’t seem to be affected, which may have just been good luck, but I remember it changed my zero 3 1/2 MOA at 100 yards. I guess that by itself doesn’t matter much but it xid surprise me a bit. I have to leave the can in NZ, but hopefully I can visit it again soon.😄
 
In Canada whatever 7mm floats your boat. Other places, short barrels and suppressors are a thing so cartridges that can be made to shoot fast out of <20" barrels are the new hot thing. That is why 7mm Backcountry.
