Thought the 308 was the most accurate... 6.5 put some doubts....

In the middle of the summer i bought myself a Icon P.H. 6.5 Creedmoor and i discover a caliber unknown to me, i found out the long distance accuracy and how good this caliber is.... Lately i bought at Tradeex a Swedish Mauser Sporter in 6.5X55 and after restauring the stock i took it to the range with 4 box o S&B 140 gr ammo, with open sight and commercial ammo i was impress by the accuracy of the 6.5X55, i guess with a tailored handloads and a scope this rifle could be an easy MOA... I have been a 308 fan all my life but now i have some...doubts... JP.

My family has some sportered 6.5 X 55 rifles. We don't punch much paper but they are hell on coyotes; flat shooting, low recoil and noise.
I've got a full wood Carl Gustav. While it's capable of the same accuracy as the others; it's hampered by it's open sights. But I can't bring myself to D & T it, too much history.
Apparently the BC on the 6.5 X 55 is really good.
Big fans in our clan anyhow.
 
Somewhere along the line you have to decide what accuracy is. If you believe that accuracy is the ability to put bullets close together, then you can look at the .308s success in hunter benchrest.

If you believe that accuracy is the ability to put shots into the center of the target, then you look at a wind chart, go to an F-class match and conclude that a .308 can't compete against a .260 on even terms. That's not to say that the .308 can't win, but that the odds shift against it.
 
The 6.5 just open a new perspective for myself on shooting before for me long range shooting was 500 metres or so but this summer being able to shoot and touch as far as 800 yards really spark an interest that i never had... More and more i look to buy a F-class rifle like a 6.5 X284 Norma in Savage or a Savage 12 Palma in 308 with a Sightron or March, the biggest they sell, i can shoot ok with the right tool, this is a new chapter for me in shooting... They says , you are never to old to learn a new trick... Cheers. JP

Depends whos and what wind chart?308 can not copete? pop.
 
As I have said many times before...If I had to have just one caliber of rifle it would be the 6.5x55. IMHO the cartridge is an outstanding performer.

I have a full wood M38 husk' from the 40's.
And a (someone else bubbaed) sporter version.

Simple, its not hard to find combinations that drift about half of what the .308 does.

Example. If that shooter can dope wind within 1 MOA, then the .308 guy has to dope wind within 1/2 MOA to break even. Needing to be twice as good is a tall order, and a considerable handicap.
 
Baribal this is exactly my rifle, even the double rear sight blade, you know your SM... Thank you... JP.
 
Well, Mauser may not be in my veins but sure is in my heart...

In the 6.5 caliber, - BTW, it was called 6.5X54 for the civilian market prior end of WWII -there was these models marketed by Vapen-Depôten;

M 30A - Cut-down military stock (with finger grooves) - no pistol grip straight bolt handle (M/96)
M 30B - Cut-down military stock, slim fore end - no pistol grip - Bent bolt handle - M94 or M38
M 30D - What you have
M 30D Lyxutförande - Deluxe Stock - Schnabel

But, even before 1947, you had the following models too. So, I can't say if you really have a M30D or if you have a M 3D, but anyways, it's so similar that we usually can't make the difference.

Exactly. :agree:

Ok Ardent show me and everyone else what NA game is so darn tough as to be able to survive a 6.5x55 bullet in the vitals...

Bison, Grizzly, Polar Bear if you're the fortunate few, even just a big moose or elk I want more than my 6.5. I also do a lot of hunting off the continent and don't consider hunting to end at the coasts of Canada when discussing 'one rifle'. :)

I don't know if that follows. The advantage the smaller caliber bullet has over a larger one is that bullets of equal SD and BC tend to produce less recoil at the same velocity when fired from cartridges of similar capacity. The advantage of the larger caliber is that a bullet of any weight can be driven faster than a small bore bullet of equal weight at the same pressure from a cartridge of similar capacity; or bullets of greater BC are driven fast enough to equal the time of flight to the target of the smaller faster bullet which means that the effects of gravity and wind are similar.

If we consider a bullet that is 5 diameters in length for example, the larger bore will always have the advantage over the smaller, a .264 bullet would be 1.32" long and the .308 would be 1.54" long which represents a significant discrepancy in mass. It follows that the higher BC of the larger caliber would mitigate the velocity advantage of the lighter, smaller, bullet provided optimal bullet styles were chose in both cases.

In the case of the 6.5 and the .308, there could be as much as a 90 grain discrepancy in bullet weight to equal the SD, and the heavier bullet typically has a BC advantage when both are designed to shoot at long range. Yet if we look at the 6.5/155 gr MK in a .260 Remington and the .308/240 gr MK in a .308, velocity would be very similar when each was fired from similar rifles.

Wind drift is a function of force against the bullet over its time of flight, much like the bullet drop is a result of the force of gravity working on the bullet over its time of flight; the difference is that wind is less consistent over distance than gravity. Given equal time of flight to the target in equal wind conditions, drop and drift would be similar in both cases, and certainly not enough to declare one as having a practical advantage over the other. Now if a shooter freely chooses or is forced by regulation, as is the case of Palma shooters, to choose an inferior bullet, that is a different problem.
 
The 6.5mm x 55mm Swedish will do anything a 270Win will do, but with less kick, less powder, and has a better selection of bullets If you reload, it's alot of fun! Anyone that tries my rifle falls in love with it. Even shot moose with it!
