What distance to you find excellent target accuracy with a non-Pal BB rifle ? I recently got a Daisy Mossy Oak BB rifle for quiet target shooting indoors. The manual rates it at max 16.4 feet for targets . Mine is not great at that distance for tight groups but is excellent at 14 feet with the Hornady Black Diamond bb ( the Umarex and Daisy Zinc not as good).

So , with this 335 FPS rated rifle, is 14 feet to short a range to be satisfied with for this purpose?
My Umarex Morph rated at 495 FPS is excellent up to 18 feet in comparison to this Daisy.

Shoot it at whatever distance you need to, to make groups you are happy with and to hit what you want.
As you improve, you MAY be able to move back a bit. Be aware that most smoothbores will throw erratic projectiles
at times.

With smoothbores (BB guns) shooting round balls (BB's), the closer the BB's are to the actual bore diameter, the more accurate
they should be, with the closest shot to shot velocities.

The further out the target, the more time there is for the BB or round ball to take on a spin and think it's a curve-ball, slider, drop or knuckle ball.

Thus, the higher the velocity, given a nice snug fit to the bore by the projectile, the potential for better accuracy at longer distances

as the higher velocity will project the ball further before it takes on a spin.

This is the reason some air soft and paint ball guns used internal barrel shapes and/or harmonics/vents to put a deliberate back-spin on the

round projectile.

The backspin would cause more consistent accuracy, just as rifling imparts a stabilizing spin on a bullet - or patched round ball that is spinning/rotating around it's axis.

The back spin would cause the projectile to rise, but do it quite consistently, so this could be adjusted with adjusting the sights.

In a nut shell, BB guns do not have a very long accuracy range.

Here is a 5-shot group with my 20 bore, smoothbore flint lock shotgun, using cloth patched .595" round balls. Note, this group was shot at almost 30 yards. The reason for this longer

accuracy range than your BB gun, is that the ball is tightly patched inside the bore and it is traveling at approximately 1,300fps muzzle velocity.

Because it is a smoothbore, there is no rear sight.

I wouldn't call Daisy BB guns that accurate. Mainly meant to teach kids basic fundamentals and shoot cans.

Agreed. I assume there may be better accuracy in the PAL rated ( over 500 FPS) Daisys or other makes.
At least, my Daisy 840 has better build quality than the similarly priced Crosman 760 which as declined in performance in recent years
in my experience. I would not want to spend $$ on a BB airgun .
