190's or 220's???

[mceod]

Looking at shooting a bit farther than 1000 yards with a 300WM. Would 190's or 220's help me get out that far? Going with Southwest Ammo, it looks like the 220's give up about 100 fps, but I'm assuming the heavier projo's will help buck the wind a bit better.

Any help would be great.

Find whatever your gun likes. Assuming quality match bullets, 10 grains in a heavy .308 won't make much of a difference at 1000 yards since both will stay supersonic past 1200 yards. Bullet design will play a larger factor in wind resistance than 10 grains at that weight.

I worked up a load of 168 amax at 3100 fps. I haven't shot that far with them but according to brian litz's solver they would stay supersonic out past 1100 and somewhere in the 1500 fps range at 1k which would be plenty for effect on 2-legged creatures.

Part of my draw to the 300 win was how flat it shoots. When you get up to 200 grains plus, the trajectory looks more like a .308. This is why I like the 168 to 180 grainers.

The 210 vlds, however will get you out to around 1500 if that is your goal.

These are what i'm looking at to get me going until my reloading setup is, well, set up.

Bullets are SMK, which I have some familiarity with in the 168's and 175's I've shot through my M1A. I think I'm just going to have to take a chance with both and see which one my particular barrel likes best.

That's the best plan. Don't buy a lot before you know what your gun likes.

My gun really likes federal gameshok 180 grains (.5 moa) but i wouldn't bet on consistent down range performance past 400 yards.

Btw - i can load those same rounds for about 65 cents (not including brass). Reloading is most economic for match ammo. If you are shooting this type of ammo $1 per shot is a significant cost savings. For a simple rcbs rc setup you will pay for it in 600-1000 rounds depending on what brass you buy and how crazy you go on brass trimmers and powder measure.

We are currently using the 230 gr Match Hybrid Target by Berger and they are performing great, just a thought!!

I would recommend the 208 Amax. To become good at (E)LR, you have to shoot a lot, and the 208 will get you far out for a low cost.

Other bullets I have used with success are the 225 gr Hornady, and the 230 gr Berger.

They will all get you past 1000 yds no problem.

Here is a open source link where Crane has done most of the test for said projectile.

The 208s are what u would like to run, however, I can not seem to find them in a factory load and don't reload yet.

Re: 190's or 220's???

If you're limited to loaded ammo, the 220's will dance all over the 190's at distance. But as has been mentioned, 208, 215, 225 and 230 gr bullets will have a sizeable advantage in elevation and wind over either.
