Assuming that you’ve explored short activity rifles as of late, you might have seen a few rifles being presented in 6.5 Creedmoor. Utilizing a case comparative, yet not exactly the equivalent, as a .308 Winchester, the 6.5 Creedmoor utilizes skinnier, lighter projectiles and sends them downrange quicker. 6.5 Creedmoor has acquired in prevalence as an extraordinary determination for medium to long reach (500-1000 yards) shooting. Ballistically talking, the thin 6.5mm slugs perform especially well, intently matching the ballistic profile of a 300 Winchester Magnum, yet with a LOT less backlash and cost. Since I thought numerous others out there would be seeing star’s/con’s to the 6.5 Creedmoor versus the 308, I figured I’d really do some exploration and sum up in an article.
308 is a nice entertainer when it’s all said and done, however it isn’t the zenith for taking 6.5 creedmoor ammo shots at truly long reach. Inside 500 yards, you’re truly fixating on petty distinctions between the 6.5 CM and 308 Winchester to the extent drop goes, yet the 6.5 improves protection from wind float. At 700-1000 yards, 6.5 Creedmoor offers a generous benefit in hit likelihood.
Case Design: 6.5 Creedmoor versus 308 Winchester
While the 6.5 Creedmoor looks fairly like a 308 Winchester, it’s really founded on the .30 TC case. Advantageous taking note of on the off chance that you expect on reloading for your 6.5 Creedmoor. The 6.5 CM additionally has a more keen shoulder at 30 degrees than the 308’s 20 degree shoulder. This will make metal last longer in the 6.5 Creedmoor, however feed all the more dependably in quick firing rifles for the 308.
There are loads of match quality and . . .esteem valued metal for 308 Winchester.
6.5 Creedmoor metal is restricted. I’ve seen Norma and Hornady metal, that is it.
Metal Availability Win: 308
Right now (10/18/2015), both 6.5 Creedmoor and 308 metal from Hornady go for $38.99, so there isn’t actually an expense advantage assuming you’re contrasting comparable quality metal.
There is an astonishing choice of projectiles for 6.5mm. Little shops will in any case have more 30 cal slugs for reloading, yet most will likewise have some entirely usable 6.5mm projectiles also.
Truly, shot choice comes down to what exactly is valuable considering case plan. In 308 Winchester, shots in the 170+ grain size are difficult to load to magazine limits AND get sufficient powder and speed out of. The Sierra Matchking 175 grain in a Federal Gold Medal Match has a BC of .496 at the rates a 308 is sending it along (2600 fps). Contrast that with the 6.5 Creedmoor, which is sending a 140 grain shot out at 2710 fps with a superior BC of .526-.535, the Creedmoor is sending a ballistically prevalent projectile at higher speed. So the 308 has more determination and accessibility, however the 6.5 Creedmoor is utilizing ballistically better slugs. Those slugs drop less at reach and float less in the breeze.
For hunting North American major game (CXP2-CXP3 game), the two cartridges are practically the same and especially capable. Hornady’s GMX or Interbond, or Nosler’s Accubond will do the work assuming you want more entrance, in any case there are a lot of good hunting shots. To chase CXP3 measured game at longer ranges, you’ll in any case have to go to a magnum stacking like the 7mm Remington Magnum or 300 Winchester Magnum and the distinctions in range between the 6.5 and 308 are not worth stressing over. The 6.5mm projectiles improve Sectional Density (more lead behind less surface region) than tantamount 308 shots, which should give them better infiltrating potential.
Cost-wise, 6.5mm projectiles cost less to transport and utilize less material thus 6.5mm slugs are marginally less expensive to purchase than 308 shots from most producers. Sierra records their 140 grain HPBT Matchking in 6.5mm at $41/100, while their 175 grain 30 cal form is $44.24.
