So Will the .270 Win Overtake the CM's and PRC's?

[MajorSpittle]

I'm probably not adding much to the conversation here but I put a 1:9 barrel on my Tikka T3 xlite in .270 win and it's a laser out to 300 yards with factory ammo. Using Winchester silver ballistic tip, or the Sig Elite I can keep groups solidly under 1/2 moa. It really seems to like cheaper ammo too. Especially American Whitetail. Even the cheap ammo hovers just over 1/2 moa when I'm paying attention.
The build is a $600 Tikka that I got on sale a Cabela's for $400. An MDT LSS chassis that was on sale for $225 and a Douglas Barrel.
My point is that this build has convinced me. I really can't see any reason to not slap on a new barrel instead of buying a new platform is cost prohibitive.

I got a Tikka '06 that is a laser and shoots 208gr bullets which is heaviest I'd go. I got a 270 win that shoots most stuff sub moa.

Now for $500 I get to keep my other two rifles and add a 6.5 PRC.

If the 6.5 PRC shoots good enough, I just might sell my 270 win. Just need to take it to the range with a for sale sign. People will pay good money for a rifle that shoots .5 moa with $15 a box ammo when they can verify it.

I only need 2 rifles and my Tikka '06 is not going anywhere. '06 is as perfect as any round ever made for hunting. Perfect backup rifle.

Unfortunately the box store barrels or 99% of factory .270 barrels are slow twist and undesirable for using long low drag bullets. As I've said, my 270 shoots 130s superbly and kills deer just as superbly but at closer ranges than considered LR. That suits me just fine as I own many other LR cartridge option rifles. I'm not in a disadvantage simply because nobody (factory) makes a 270 win barrel fast enough to use low drag bullets for LR hunting. I just get a different tool out of the box. I'll keep hoping before long faster twist barrels will be born from factory rifles but until they do, I'll keep killing them at LR with today's more popular options. Remington changed hands once again so we will see where the new owner takes the company. I'm hearing possibly decent things to come.

So are you saying a 1:10 twist 270 shooting a 150 grain VLD with a G1 BC of .518 at 2800-2900 fps isn't enough for long range hunting? Berger says it will work in a 1:10.

 

[JMW67]

The 150 berger works just fine in a 10 twist been shooting it for a while never any issues 658 was my longest shot on game i have shot steel to 800 a stiff load of rl 23 was the ticket in my rifle

Nope, the 150 isn't considered a heavy 270 bullet. It's about the longest bullet that will shoot in the 10 twist barrels. I shoot the 150s in my .270 or should say I have. It shot fine but from a 22" barrel and shots only around 75-225 yards, the 130s are a better option. Right now it's the 170 Berger that needs a faster barrel. Not sure about Noslers LR accubonds. Never put them thru the twist calculator. I have no doubt the 150 if it has a BC of .518 and it's a " true bc" would be a good LR bullet. Guess you'd have to do the drop data and see if those numbers are accurate.

I have and they are pretty darn close.

There will be more projectiles coming and already are, with the advent of the .277 sig fury (which destroys the 6.5 creed ballistics-wise)

*In proprietary non-reloadable bi-metalic unobtanium cartridge cases loaded 80-90k PSI with probably propriertary/unobtainable powder in factory ammo that will be scarce at best and probably make 338 Lapua and other sound cost effective.... yeah sign me up.

In normal brass cases with normal components its a shorter less efficient lower BC 6.5 Creedmoor. Same goes for the 27 Nosler.

You want to get into a discussion about marketing hype... you picked the right cartridge to get excited about /sarc

Anyone want to take bets on when common people will actually get their hands on one of these chambered in .277 Fury? (Im not talking about industry people/shills/influencers/gunbunnies here...) Ask anyone who was promised caliber exchange kits for the MCX how good Sig is at fullfilling promises made when new products were launched. My guess is there will be enough demand for the 308 and 6.5 versions to keep these backordered for a year or two without ever having to launch the .277 version.

All that aside... I really dont get the obsession with 6.8mm/.277 bores, the ballistic form factor of these rounds is inherently less efficient than either the 7mm or 6.5mm above and below it. Your selection of bona fide high BC match/hunting projectiles is a fraction of what it is for others. So you have to drive it to higher speeds to get similar/better performance. Just look at example someone posted a few pages ago... using same weight/construction bullets the Creedmoor catches and passes the 270win at around 500-600yds even though it starts almost 300fps slower. This is a long range hunting forum, so that's a meaningful and valid example. To put that velcoity difference in perspective thats like comparing relative velocity of a 308win to a 300Win mag.

People can show data and real world examples till they are blue in the face and it makes no difference to the cult of O'Connor... which is fine. It's already hard enough to find 143gr ELD-X's right now.

Won't work. Much longer than your round nose bullet with less bearing surface. They are VLD bullets and require a fast twist barrel. I have some round nosed 160s for my 6.5 also. Long but not like VLDs. They shoot in a 10 twist also.

good to know I would only use the 150 gr thanks

I think the .270s foot hold IS hunting. It hasn't lost much if any popularity among hunters. Especially older hunters.

I guess I fit in The Older Hunter category! My long time respected rifle Hunter was Mr. 270, Jack O'conner and bow hunter was Fred Bear! Our whole family were brought up shooting 270's, Dad, Mom, my brother and myself. Before my brother passed away 2yrs ago, gave me our Dad's old Remington 700 ADL 270 that Dad modified and installed a BDL trigger guard/floor plate. I have upgraded it with a 6 x 25 x 50 Athlon illuminated scope.

To get to the point, YES this is a HUNTING rifle for sure, for 50 plus years! I think my Dad and Jack O'conner instilled a love for the famous 270 rifle. Per Jack O'conner, years ago documented, sight in 3" high @ 100 yards and just hold on out to 300 yards with no hold over.

As far as long range shooting, personally, the 6.5CM is only slightly flatter shooting but not worth all the cost and increase in reloading equipment and supplies. With that being said I wanted to see if I could come close to the Creedmoor ballistics and recoil so I strayed from our life long family load of 130 gr Rem Core-Lokt, 58gr H-4831 and CCI primer, chrono'd @ 3021FPS.

I first tried 130 grain ballistic tips with reduced H-4831. At 49.75 grs it blew me away at 100 yrs had 3 rds grp < than .2" with 2 res in same hole. Chrony showed ave of 2593 FPS.

My second test was using H-1000 and CCI Mag primer. I settled on 53grs behind a 130gr Berger VLD, which gave me a grp of .24" @ 100yds and chrono'd @ 2567 FPS.

Recoil was very mild, more like a 243 cal. Truly a fun and exciting venture to find a more accurate load for my Dad's OLD Rem 700 .270 and one to get close to 6.5CM velocity and recoil. I hope you enjoyed the trip and how I rekindled the past of shooting a GREAT caliber!
Thank you,

Hopefully there will be an optional fast twist offering. Standard 10 twist or optional 8/9 twist. Most hunters do not know anything about twist rates and required bullets for certain twist barrels. The good thing about getting a faster twist barrel is, even light bullets shoot fine in them. If only one barrel will be offered for the .270 cartridge, it'd be best that its an 8 or 9 twist, not 10.

Yes.
I would think 270 owners (yes I have one) can read as well as 223/5.56 owners. For many years we have available heavier .,223/5.56 ammo with the twist required stated. I have heard of no big problems, the same could be done with .270.

Now that is a HUNTING story - with fine tuning for shooting. BRAVO.

Uh...... 130gr bullet at 2500fps? Is that a typo or did you mean to say you were trying to replicate 6.5 Grendel ballistics?

Nosler load data for 130gr ballistic tips ranges from 2800-2950 fps out of a Creedmoor.

 

[Nomosendero]

I've killed many deer and pigs with my 10mm. Muzzle speed 1380 with 220 bullets. Energy at muzzle 800 ft lbs. At 50 yards, less than that. Kills them easily. The Ft lbs thing isn't a great thing to use for judging power. Impact velocity around 2K is simply for bullet performance. Once the bullet performs in the place you put it, it's game over for the animal. That's why placement is 100% everything.

Placement and the proper terminal performance in that right place. Apparently the 10mm provided that with your proper application.

 

[Geezer28]

I would say don't shoot the messenger but seeing as its a 270 I'm not too worried.

Ok. Know this thread is long. Know that there are some suttle differences in the cases. (6.5 PRC) but what are the thoughts on the 270 wsm. 3-400 ft/sec higher velocity 140gr Berger over 143 gr elm. When the 270 wsm first hit the market thought it could be the ultimate N. American cartridge (except big bears) IMO have had several that turned out very accurate and have dropped everything in their track from antelope to big bull elk with a couple of black bear thrown in. Must admit I have a very nice 6.5 prc from straight jacket armory that I have used on several deer sized critters.

Appreciate the expert review - but the Deer will be just as dead.
