Sectional Density

Recommended Posts

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

http://abesguncave.com/sectional-density-all-important-and-almost-ignored/

 

...and...  "Why the .308 Sucks"...   :lmao:  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...

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.

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

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 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 .

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

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.  :thumbup:
