Rogue, Thanks -- Are these hunting or LR Target bullets ?

I'm interested in the .260 as an alternative to a .243 for a younger hunter/shooter.

The .270 is an impressive benchmark for deer & sheep hunting out to 4 or 5 hundred yards.

I'm looking for something in a more compact action hence my interest in the .260 as a hunting vice LR target round.

They're target bullets that'll do just fine for hunting. I've killed a lot of shiet with Noslers of a bunch of different flavors but have moved loads over to the Amax when the options there. Lot's of elk get crunched every year with "target bullets". If the target bullets make you nervous look at the Scirroco II, even the heavy Accubombs could be worse.

I really dig my 260, nothing wrong with a 243 two of my kids use them - look at the 105 Amax.

Some one mentioned a 280, I dig my 7 mils. 162 Amax is bad ass. .625 BC is real. That makes a 708 not a bad choice at all.

The 7 Shamwow on the left is loaded with a .625 bc 162 Amax at 2.80 col.

The 300 Shamwow on the right is loaded with a .509 bc 180 Ballistic Tip at 2.80 col. The 208 Amax when you can find them would be a sweet ride, I think it's bc is .640 or there abouts.

Just shows not all bullets are the same. 3-400 yards in I don't think it really matters much for most.

For either 6.5 or 270, it's not that hard to find bullets long enough and pointy enough with super high BC's to require quick twist barrels. The trend in long range target shooting in fact appears to be 270's with 8 twist barrels.

Something to keep in mind, it is easy for any manufacturer to make higher BC bullets. But they know that longer bullets become much fussier regarding seating depths and accuracy. In target bullets the Sierra Matchking is an easy example, people look down on them because Bergers/Lapuas/etc have higher BC's. But the Matchkings are much less fussy with seating depths and finding accurate loads.

For hunting purposes, it's not worth worrying about the difference.


Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!

Rick, The 8 twist 270's with the 180 grainers may very well be the future.

Right now it's hard (not impossible) to top the 6, 6.5 and 7 mil for nice long range bullets.

Rogue would a 270 bullet have to be that heavy(180)to be comparable to a (say)140 gr 6.5?

I just ordered a 9 twist 270 barrel....will see how that goes.

Guys guys....most of you sound like a bunch of women smile ....comparing their lovers packages.....they will nearly ALWAYS choose the Longer Thicker one....yes both so similar in performance and really too close to call........and get the same job done.

Had JOC had the 260 in 1925.........till now their is not anything a properly loaded and spun 125-140gr 6.5 slug thrown from one could not do on big game, that a 277 would change the outcome IMHO.

And yes, had that been the case and the reverse happened....the 270 coming out today...in 1997 would have done FAR better than the 260 has across the board as the masses like the 'Bigger is Better' philosophy. A connection perhaps tied to their manhood that is engrained into their DNA. Gack will never change that power of that mindset..its here to stay smile

YET....Bigwhoop......what you forget to recognize....the 260 HAS been around......FAR more than 1997....in fact, the 1896 Mausers were around over a century before, in the '260 package' that was designed in 1891..... http://en.wikipedia.org/wiki/6.5x55

Now lets anyone argue that their is a reason the 120 year old 6.5x55 has survived this long, racked up TONS of Swedish Moose kills and other game around the world, as all 6.5s at this performance threshold. AND just what round won this 1K shoot....not a 277.......a lowly 264....at 6.5-08 speeds...

1999 British Long-Range Benchrest Championship was won by a Tikka Continental in 6.5x55. Group size was an almost unbelievable 10 rounds into 4.4 inches at 1,000 yards. Anyone looking for an accurate out-of-the-box varmint rifle would do well to consider a Tikka.

Above: http://findarticles.com/p/articles/mi_m0BQY/is_2_49/ai_95680073/pg_2/?tag=mantle_skin;content

Seriously...either will satisfy when properly used as most in the know might admit if cornered.

I am with Gus K on this one.....but won't argue with BobinNH....nor Scenar smile Well....might 'rib' Bob on occasion...but in the end both men anchor game....and that is a fact...beyond 'Gack!'

Su35, Patrick James, etc...all are right. Hell...I think BigStick would even 'Get R Done' if he had too with either...and a few minutes of range time....lest he chooses a 7/08 or WSM as a staple.

Now that this is settled.......what to do as today's forecast is 109F before the heat index frown

Now if Big Green wants a new 'baby' perhaps they should re-shoulder and do a 270AI properly spun and stuff new high tech high BC/SD controlled mushroom 'Corelokts' and name their baby the '277 NBM Express'....Non-Belted Magnum Express. Unless of course Winchester does not first make their '270 WLR'....Winchester Long Range. LOL.

Optimum bullet choice would no doubt kick the 277 up a notch w/o magnum recoil producing powder charges...though at more recoil than a std. 130-150. Not optimum BC but the old 160 NPT in a 270 WCF has done things consistent with the 7 RM and 175s...though at lesser distances due to its nose.

No doubt...if/when a fast twist 270 hits the scene...w/proper ammo/bullets....then a new debate merges....and this time it will be...270 vs. 6.5-06/264 WM smile

If you haven't already, check out this website. Matrix Bullets are making some waves in F Class competition. The owner is a great guy too.
http://www.matrixballistics.com/

You might be surprised in which competitions his 270 bullets make an appearance this year.

Some VERY interesting BCs, esp. for the LR guys.

I believe Sierra did make a 155 MKHP long ago, but they never found alot of favor and ultimately may have been dropped.

Wonder if there may be parallels for the 6.5/155 combo vs. a 270/180. No doubt a QT is needed to spin a long bearing surfaced 277 slug, and that will induce more drag - in bore, and affect pressure curve.

Speeds possible in a WCF? Guessing 2600-2650 in typical 24" bbl.

I've used the 135 SMK a fair bit and to 600 it did very well for me. Long as I had dotz or turrets I can go a long ways with the .270.

Dober, I have a bunch of 135SMK's loaded up for steel practice. They shoot great and match up perfect with the 140 Accubonds.

Smoked a goph with one earlier this year, it died.....grin

Years back Speer made a 180 grain round nose 270 bullets. Wildcat Bullets makes a 190 grain, but the 270 win doesn't have the powder capacity to drive them fast enough, but the RUM case does

I'd surmise the 180 RN would stabilize since a given twist seems to handle heavy RNs often when not doing the same with Spitzers.

I'd imagine on short/medium ranges the 180 Speer did fine - esp. if it did not yaw (stayed nose fwd vs. tumbling) during penetration.

Matrix is listing a .7828 BC with a 175 grain in .277, .7381 with the 165 grainer.

They're showing .8071 BC with a 190 grain 7mm and .7136 with the 168 grain 7mm. A standard 1/9 might even spin the latter?

Looks like I'll have some fun stuff to play with when I get home in a few months. Pretty cool stuff.

I may be wrong, but Speer made a 170 grain RN in 270, not a 180...

I have a 170 RN listed in a couple of old Speer Reload Manuals from the 60s, when they list the bullet as new...

I also have half a box of them given to me by someone who said he would never use them...they are somewhere around here...

Maybe I'm strange. When I buy a rifle, first I figure out what rifle I want, then I look for one chambered for a round to do what I want it to do. When I bought my main deer rifle, I decided on a CZ-550 Premium(no longer made was available in 30-06 and 270), then I bought one in 270 because it was what was in stock at the local shop at the time. Same deal with my Savage 99, got a .308 but could have been .300 Savage and it wouldn't have made a difference to me. On my budget you can't bee that fussy. laugh
