6.5x55 Swede versus 260 REM

Not long ago I went through the same exercise.
Deciding between a CZ550 6.5X55 or a Remington 700 Mountain DM 260 REM.

It was a very difficult decision.
However, I choose the Mountain Rifle because the off-the-shelf stock
fit me perfectly.
And, the Mountain Rifle had a detachable magazine.
I like a detachable box magazine.

Moreover the 260 REM factory loads were approximately 150 fps faster than the 6.5x55.

However, in hindsight I should have considered one other factor ... bullet drop compensation.
I will be buying telescopic sight with a bullet drop conpensation reticle.

The 6.5x55 Swede 140 grain load better approximates the bullet drop compensation ballistics
for scope reticles calibrated for the 7.62x51 NATO 175 grain sniper load.

While the 120 grain loads closely approximates the 5.56x45 NATO 77 grain sniper load.

The 260 REM is reasonably close.
But, the 6.5x55 Swede is closer - using factory ammunition.
As such, the 6.5x55 Swede would have been an almost perfect choice
for scope with a bullet drop compensation reticle.

The hash marks and tic marks on the vertical crosswire
are calibrated to two popular long range service rounds,
the 5.56mm NATO SS109 at 2800 fps (carbine velocity)
and the 7.62mm NATO 118 LR at 2600 fps (rifle velocity).

After properly zeroing the rifle or carbine, the tic marks will correspond
with bullet drop at the ranges listed below.
