Home Forums Hunting & Shooting Long Range Hunting What cartridge/bullet/caliber 06 and below is king?

As far as I know and as far as my research has taken me it has to be the 280AI with the Sierra SMK 175grain.

Am I missing something? The 208amax in the 06 is very interesting. I never loaded the 30cal SMK 240 grain in an O6 yet.

For 30-06 based cartridges and below what is the king of the hill for actuall killing critters at the longest distance?

Is there a 6.5 bullet that I am not aware of that beats the Sierra SMK 7mm 175grain???

The .284 162 Amax matches or exceeds its BC and can be pushed faster. The 140 Berger vld out of a 6.5-06 AI is good too.

In my opinion the top long range contenders would be,

6.5-06 AI, 140 gr Berger
280 AI, 180 gr Berger
30-06 AI, 215 gr Berger.

Depending on how you want to weigh drift, energy, and mass.

Thanks... You just saved me a lot of reading! LOL.

I have only focused on Sierra, Nosler and Hornady bullets in my experiments so far. Will have to take a close look at the Berger stuff. Thanks again.

I like these practical questions. Thanks to the OP.

If you want practical, Just build a 284 Win or 6.5-284 and be done with it. Easy choice over AI-ing the 06 hull IMO......

For practicality one could simply go plain vanilla 30-06, 280, or 6.5-06. Or the AI'd version.

Finding brass is never an issue, if you have a resizing die. You can pretty much always find 30-06 or 270 brass, or ammo to cannibalize the brass.

That is a big part of my thinking these days.

Sierra B/C's
http://www.sierrabullets.com/resources/ballistic-coefficients/

The 308/210grainSMK's are 610B/C
The 308/240grainSMK's are 711B/C

Once upon a time I flung some 240's our of a RUM, but I never really did all that I wanted to do before trading.

The 240's I noticed do cost about twice the price as other offerings, or at least they did at the local gun store. Has anyone out there loaded 240's in an 30-06?

Sierra is offering some new TMK bullets????

There will be six (6) new TMK bullets, two in .224 caliber, and four in .308 caliber. The six new tipped bullet types should be available in �early 2015″. Sorry, Sierra will not be offering 6mm, 6.5mm, or 7mm TMKs for the time being, although Sierra will introduce more TMK varieties in the future. Currently, Sierra is focusing on �the most popular calibers�. Notably, the new 22-Cal 77gr TMK has a 0.420 BC � identical to the BC of Sierra�s 80gr non-tipped HPBT MatchKing. So, you get the BC of a heavier bullet in a lighter projectile that can be pushed faster. That�s big news for .223 Rem and 22-250 shooters.

I love my 284. Great cartridge.

The more that I see peeps struggling with their cartridge choices, the more I like my 300 win mag.

I can download it or upload it for vermin from 1800-3600 fps with 110gr speer spire points, to heaviest loads at 300-400 fps over the '06.

It is arguably the most versatile cartridge on terra firma.

When talking long range nothing "30" interests me in the slightest.

Nor does the 6.5-06 or 6.5-06AI when the 6.5-284 exists.

Same for the 280AI. Gimme a 284 Win, or 7mm RM......

I have done very well with the 300 SAUM.
Nisika Model G RBLP.
Tooley Tracker from DB Supply
Obymeyer AMU+ 1-11 twisted.
Scope in the pick is a 5-25x56 PMII I swapped out to a 12-42x56 NSX.

The groups are stunning.

I bought a box of 50 of the 240 SMKs several years ago just to see what was possible in the 30-06. I loaded them, without moly, over RL22. I was able to get just over 2600 fps from a 26" barrel. They shot very well at 100 yards, and past 1000.

Thanks MM

I'm gonna plug that MV into my exbal and ponder the curves.

I scrounged up this very interesting article on the 284. Brass price and avail???

Even on a short action, a 284 Win will get you a minimum of 200 fps more, with considerably less powder and recoil.

Comparing .308s to 7mms and 6.5s is a lost cause, in every regard. This coming from a guy who owns 2 308s, 2 30-06s, and a 300 Win Mag.

Bulding upon the 284 Win case, seating long and increasing powder capacity thusly, is the only way to go here, if maximum peformance is the true goal.

Skip the 30s, and anything based on the 30-06 case.....

What velocities do you get with 140's in the 6.5-284?

The 280 AI and 168 ABLR's at 2960 have been getting it done for me !

284win brass; 65cents per and unavailable, "seasonal run"

What is the magic on this 284? I have always skipped over all the articles on it, just was not on my radar screen. It has 2 grains less water capacity (I think) than a 280.
