I am looking for opinions on this caliber for long range shooting. Just steel and paper. I have a 308 and 223 already and was heavily leaning towards a 300 win mag next. I am considering the 7mm because my brother in law is also getting a hunting rig in this caliber so I can get reloading for half the cost as we would share tools and components.

I see the 7mm has a high BC but the 300 has more bullet choices not to mention I already load 308 and have a lot of projectiles on hand. Thanks for any advice.
 
The 7mm Remington has been used by the US military as a sniping round. straight from Wikipedia.
Because of its flat shooting nature and the relatively tolerable recoil, the 7mm Remington Magnum is especially popular for Western plains use in the United States, as well as for use on plains game in Africa, where longer reach than commonly achieved with the .30-06 are most often needed. It has also been chambered in sniper rifles as the US Secret Service counter-sniper team has deployed this cartridge in urban areas. Popular online gun author Chuck Hawks calls the 7mm Remington "one of the great all-around rifle cartridges."

I have come across that info in the past. thanks
 
I love my Howa 1500 in 7 RM. It is sighted at 200 yards and is doing sub moa at that range. Have not had to take it farther as it is for hunting. I would not be afraid to take it out much farther. I would recommend a good muzzle break as it makes it much nicer to shoot.
 
Berger 180gr Hybrid or VLD from 2950 to 3050fps.

Or Hrn 162gr Amax or BTHP... very inexpensive LR plinking

If you can see it, you can reach out to it. 1mile is no problem.

Very accurate... just a bit hard on throats but in a shorter barrel, very effective vs smaller cases.

My smallest group every shot at 1000m was with a 7RM. Built a few with excellent result AND way less temperamental then some small cases pushed hard.

Is the 7mm capable of a mile? I am a long ways off skill wise but I would like a caliber that will carry me well past the 308.

Of course it is. The distance at which it go's below the sound barrier is critical, but that should be somewhere around 1700 yards for the 7mm.
 
Thanks for the info. I am excited to get into a 7mm and work up some loads.

On a side note, considering a remington 700 sendero or a tikka hb varmint. I handled the tikka and the action is unreal. Stock is crap though

Far less important then you may think. Many bullets will go transonic and then subsonice without any fuss, change of direction or even accuracy.

The only way to know for sure is to test at LR. But you are more likely to have success then failure given how many modern bullets can fly subsonic without issue.

The Hrn Amax that I have shot in various cals seem to handle this better then others.

I defer to your greater experience Mystic, I am only quoting what I've read. To me a long shot is between 4 and 5 hundred yards with a hunting rifle and your garden variety Leopold. (3X9x40)
So what makes one bullet better than another when crossing the sound barrier, BC, or does it have something to do with rotational speed? (RPM)
Long range hunting is something I am stuck with where I am now, but I don't think I will be taking shots out to where any cartridge considered to be long range, would go subsonic.
 
It has to do with the bullet shape and balance (aerodynamic and static) of the bullet. Way too complicated to get into it.

The easiest way to know is to launch the bullet way out there and it will either hit or not.

Luckily many of the bullets we commonly use will go subsonic without fuss.

I will test 100 to 200 yds BEFORE it goes subsonic and track accuracy... Repeat where it is supposed to go transonic (figure on 1350 to 1150fps). A clear sign is a big change in vertical tuning.

Then go 200 yds AFTER it goes subsonic (1100fps as an easy number to remember). The groups will either stay stable or it will be like a shotgun.... impossible to know where the next bullet is going to go.

It is repeatable and alot of fun to view. Was shooting with a gent and his 308. We stretched out to 1200yds and it was tracking really nicely.

Then there was a clearing around 1350/1400yds and the bullets just dissappeared.

From large pizza box at 1200yds reliably to missing a grassy and sandy hillside a bit further out.. It was a hoot plinking on target then moving further and Nothing.

Winds were not an issue.

Have fun and prove to yourself what will or will not work for you twist and set up.

Interesting info. As a side note, I scoped myself with a 7mm the other weekend. Was leaning too far in and it kicked a bit harder than I expected, buddy and I had a good laugh at that. Not helpful, I know.
