30-06 vs 300 WSM vs 300 Win Mag look at these numbers

Looking at building an intermediate range rifle for target and hunting. This will not be a bench gun, nor a walking rifle but a field gun for shooting out to 1k as a stepping stone to longer ranges. At the moment we have been shooting regularly to 600, can hold 1/2-1 MOA confidently and are ready to move a bit further out. Won't be shooting game at these ranges any time soon, still looking at ballistics etc.

Some interesting numbers- impressions welcome:

Shooting a 180gr bullet, with a 300 yard zero and a 10 mph crosswind , the 30-06, 300 WSM and 300 Win Mag come in accordingly:

30-06:
Drop @ 600 -59", drop @ 1k -295"
Wind @ 600 27", @ 1k 88"
Ft/lbs @ 600 1350, @ 1k 710
Powder used 57gr of H4350

300WSM:
Drop @600 -53.5", drop @ 1k -267"
Wind @600 26", @ 1k 84"
Ft/lbs @600 1485, @ 1k 780
Powder used 64gr of IMR4350

300 Win Mag:
Drop @ 600 -51, @ 1k -256
Wind @ 600 25", @ 1k 81"
Ft/lbs @600 1545, @ 1k 814
Powder used 80gr of H1000

So for this application there doesn't seem to be a clear winner. All rounds have their merit. As this is a field gun I will use a brake if necessary but would prefer to avoid one. The 30-06 obviously uses the least amount of powder, least amount of recoil and the best barrel life. On the other hand the 300 Win Mag shoots the flattest and hits the hardest.

There are other rounds to consider of course, the 7mm mag, the 280AI, the 264 Win Mag etc etc etc.

The ultimate question is still which round will give the best results, use the least amount of powder, have the longest barrel life etc.

Not asking much right? Everything is a compromise.

For those who have done it before, if you had to start all over again, which would you choose, and why?

6.5-284. I have a 3006. Love my 3006 but wanted the high BC of the 6.5. However all of this stuff is relatvie to the FPS of the bullet combined with BC. Shoot a 210 vld at 3000 fps and see what it will do. Impressive.

I choose the 6.5 for light recoil and LR BC bullet with SD for smaller animals such as wolves. I bow hunt for deer and elk.

@ 600
drop 47.3
wind 17.9
1482 ft lbs

@1000
drop 217.2
wind 56.6
965 lbs

56 grains retumbo

52.5 grains retumbo and a 160 produces more drop but more ftlbs energy. 1505 and 1011.


*** The rule of thumb is to shoot the heaviest bullet, with the highest BC, at the fastest rate. Where things get complicated is when BC is low, speed is fast, or BC is high, and speed is low. You just have to run the numbers. It seems like the .264, .284, and .308 calibers all offer something for everyone. It seems like an endless sea of options that cover every aspect.

Good luck.

The 6.5x284 is a great round for sure but how does it compare with the others for barrel life?

Well, from what I am told it sucks. 800-1200 rounds is what I hear. I have about 700 thru it now. I loaded them hot too. 2970-3000 fps. I had a new load I played with for awhile at 2910. The 160's are at 2700 and I am getting to know that bullet better and better. I ordered another 100.

That's the thing about rounds like that- the performance is there for sure, but if you want to be able to shoot a lot (which I do) then you run into throat erosion issues. Again, everything is a compromise, not looking for a free lunch, just the best round to start with.

I love a 30-06, but configured for a carry rifle. Light and handy for game to about 600 yards. When trying to extend the range from 600-1000 yards, I'd prefer a heavier rifle, more scope etc., then the .300 Winchester would be my choice.

Good points. The idea with this build would be a heavier rifle to reach out to the longer ranges, if it were 30-06 then it should get close to factory 300 win mag velocities. Obviously a similarily built 300 win mag would extend the range some. The real question is how much, and at what cost.
