Sectional Density

Why Sectional Density is so important...   (wait for the "Part 2"...)

...and...  "Why the .308 Sucks"...     Seriously, this is good info.  We need to shoot heavier .308 bullets.  I've been doing it for awhile now, and I'll go even heavier, now...

Good reads

He's preaching to the choir here, I haven't shot anything lighter than 165 grain in a .308 in over a decade now, typically 175s.

Great read thank you brother. I get it, I'll just keep chunking those fatties.

We're going bigger than that, brother - my 178s will be the bare minimum.  195s, 208s, and 220s coming up. 

These bitches:

195 BTHP Match, sectional density 0.294 with a .550 G1 BC:

195 ELD Match, sectional density 0.294 with a .584 G1 BC:

208 ELD Match, sectional density 0.313 with a .690 G1 BC!!!:

220 ELD-X, sectional density 0.331 with a .650 G1 BC:

I know I can load .308 Win with that 220 above, but I don't know if I can get this 225 in a .308 case - but I can get it in the Win Mag case!

225 ELD Match, sectional density 0.339 with a .777 G1 BC!!!  Holy shiit!!!

I gotta stick with what will feed out of a PMAG, and I don't expect that anyone will stick around to complain that I should shoot a ballistically superior round at them. Other than you dorks of course....

What would be the heaviest that would work in a Pmag ?

If you're handloading I believe you can backset up to 200gr enough to fit the mag.

I know the new FGMM 185gr Bergers will fit.

     I have settled on 155gr.,308 Bullets  , I will probably never shoot 800 yards ( but would love to ) & if I need Heavies , I have them tested & loaded already . The 155's work very well in both my 308AR's , sub MOA & in CQB , less recoil for better follow up shots .

  Not a thing wrong with the 308/7.62x51, its a great cartridge for Combat , and proven !  

  The Arthur can dislike the 308 all he wants , its his right to do so .

For Hornady 30-cal projos, you can load everything up to 208gr to 2.800", which should work in a PMag.  You CANNOT load the 212gr ELD-X to that, it gets a COL of 3.000".  Oddly, you CAN load the 220gr ELD-X to 2.800". 

I'm loading some of those long, skinny bitches up and testing them out at distance.

I have some Hornady 208 gr ELD’s, think I will give them a try next spring. As my press is in the garage and it’s gonna hit -14 on Monday and Tuesday, might be a while. Those ELD’s also make a very accurate 300 Blk round.
