Also known as 7mm Practical. I've come across this a few times and it seems to be getting more and more attention and was curious if anyone on here that has tried it and reloaded it and if they would care to share their opinion on it. I'm liking what i have read and heard so far, but wanted to see if anyone else here has heard anything on it (pros and or cons). This would be for precision long range work.

What is the advantage over the 7mm Rem Mag? It seems like a 300 Norma Mag vs 300 Win Mag situation (similar ballistics with one having the theoretical benefit of a longer neck. Not trying to start an argument, just curious

If you're planning to reload I think the 7LRM may be more attractive due to not having a belt. You could also look at the 300 Norma Mag necked to 7mm. As a sidenote, AFAIK the 7mm-300 is not the same as the 7mm practical. The 7mm-300 retains the same 25 degree shoulder angle as the 300, while the Practical is blown out to 30 degrees.

Marking this thread for interest. Doc, what are you running now? I'm such a big fan of 300WM and see such little advantage of these other offshoots, I've never studied them much. But maybe I learn now.

My next gun will be 338LM. Good luck on your search.

Honestly couldn't tell you. I been reading that many have been able to make accurate hits out past 3,000 yards with this round. Other than that, I couldn't tell you all the inside scoop of this round vs the others that you mentioned. I've taken notice that its becoming more and more popular among long range shooters and was curious if anyone on here has had experience with it.

I'm running a .308 right now, but I'm saving up for a custom gun and starting to think what I want it chambered in and found these vids (plus others that you can find browsing around)

I agree with you and am not a fan of the wild cat cartridges, but this one really caught my interest. I too have been looking heavily into the .338LM.

The .338 is awesome but what are you going to do with it?

$5 a shot even with reloads is too much for my blood.

Honestly all I kill is paper and steel so the larger calibers isn't something I have researched heavily but the 300 Win mag seems to be a favorite with the long range shooters that step up past 2000 yards.

Agreed, and that's why I have been looking into the 7mm-300win due cost.

I'm a fan of staying on the beaten path... i.e. .308, 300WM, etc. It makes equipment, dies, resale, etc... much more headache free.

I just watched the video. he explained the "300 brass is necked down to 7mm". I honestly thought that was what 7 rem mag was. How different is 7mm vs 300wm brass. What do you gain? What are the ballistics?

Learn me up.

I believe the 7mm Rem is shorter and tapered differently. The .300 has maybe 10% more powder capacity.

We are sending a 208 AMAX over 3,000 fps and a 225 ELD over 2900fps with 300WM. Gotta wonder what this bad boy will do and can it beat those ballistics. It is interesting. I favor heavy bullets and longer barrel life but it sounds cool.

7mm Remington Magnum at left, Practical on right.

I always thought the .270 Winchester was the worlds best non-belted magnum. ;)

I guess if someone was really in love with 7mm and wanted more... We played with 7 mag for a little, but it never really grabbed us.

I'm considering a 7mm Norma personally.

Looks like Bigedp51 beat me to it. Thanks for posting that link. I prob should have posted it in my original post.
