Economics- .308 vs .300WinMag

Hi guys,

I'm pretty well settled on making the .308 my first rifle for use for going long (although I do have a .270 to play with until then) but want to throw in the mix the economics for maximum shooting enjoyment.

1) What is an average load for the .308 running YOU?
2) What is an average load for the .300 WinMag running YOU?
3) What is the brass costing for for the .308/.300WM?

Could you help me break it down? Here, the brass at one shop for the .270 is $28/100. I forget what the cost was for the MatchKings.

Also, with any waste or such, how many loads are you getting per container of powder?

I'm asking all this as it appears that the .308 will end up substantially cheaper to reload, but I haven't run all of it and don't know quite enough to do a very good job of it.

Anything else I've missed in the consideration of this subject, please just set me on the straight and narrow!

Re: Economics- .308 vs .300WinMag

I dont shoot either a 308 or 300 but a pound of powder contains 7000 grains of powder.
You can do the math and figure out how many rounds of powder youll use by weight of load.
The 300 win will go upwards of 70 grains plus netting you around 100 rounds per pound. The 308 is almost around 200 rounds.

Re: Economics- .308 vs .300WinMag

the cost of the bullets, primers, and intial brass will be the same, however the performance gains at 600 plus yards are worth the extra cost of powder to me. If you are on a tight budget get some friends together an buy the powder in 8 lb jugs so you can save on hazmat charges, jm2cw

Some math with it, and what about brass life?

Ok, here's some math. Tell me if I'm getting off base.

I figure that, in looking at different recipes and the books, an average load for the .308 could be in the 42g area. So, 7000/42=166 loads. This is allowing nothing for loss of any sort.

The 300WM looks like there is around 70g per load avg, and if that's correct, you're looking at 100loads/pound.

So, if I bought powder at $20/lb from local supplier then I have $0.12 per load with the .308 and $0.20 per load with the .300WM. This is powder cost only.

Russ Haydon's Shooter Supply has Bulk Brass at $24.00/100 for .308 and $34.00/100 for .300WM. Lapua brass at $0.37 per for .308 and $1.02 per for .300WM

Primers seem to be about $0.12 each.

Bullets (Match Kings)seem to be about $16 for a box. How many in a box? I don't know, but that's what it was at the same source. Let's call it 50 for arguments sake. That's $0.32 per.

Using these figures, I come up with a range of $0.80-0.93 for the .308 and $0.98-1.66 for the .300WM. Do these sound like I have the figures in there close? What am I missing?

These were with no tax figured in, or shipping costs. I do have shops in the area to utilize, though I've not priced them. But this should get me a good idea of what I'm looking at, I would think.

Also, what kind of brass life difference is there between Win Bulk and Lapua? Is that going to figure in here significantly?

Thank you

Re: Some math with it, and what about brass life?

me personally, i would not use the lapua brass. it is no doubt the best brass you can get out of the box, but unless you are trying to make a living at shooting i would advise against it. win. brass is cheaper and as durable. you can buy the powder in the one pound cans, but you will never get the consistancy as if you had 8 or more pounds of the same lot number. i know that spending 100 plus dollars for 8 lbs sounds like a lot plus hazmat fees. trust me i bought 8 lbs of retumbo with the haz fee for less than i could get it at the local shooting supplier.
with the powder capacity of the 300 win you could use some "pulled" powder that is aroud 50 or so dollars for 8 pounds the 308 would not be able to utilize these slower powders

Nope, I appreciate the reply. I *did* ask for opinions and I thank you for yours.

But I'm a bit unclear on one thing. What is the "pulled" powder? Is it "pulled" as in regected or something?

On the brass, I just wasn't sure if people were getting 2x or 3x the life out of that brass than what they were the Win, thus offsetting the higher cost with more uses and enjoying the plus of having the same cartrigdes.

More thoughts and opinions would be greatly appreciated. I'm currently reading an older book by Carmicheal, have "Precision Shooting to 1000yds" coming to get to read, and am working to absorb several sites on this, not to mention having the sierra and lyman manuals I keep referring to and reading. I need some perspective to help filter all this info.

Thank you

Re: Some math with it, and what about brass life?

The pulled down powder is just military surplus that they have pulled the bullets on loaded rounds to reuse the powder.

Another thing to consider is recoil. The 300 Win will kick significantly more that the 308.

Another cartridge to consider might be the 300 WSM. I haven't loaded for one but I THINK(might want to double check me) that you can = the performace of the 300 Win(or at least very close) w/a little less powder.

I would also recommend using the 1 lb containers until you have settled on a load. Then buy a hefty supply.

Good luck,
