Gamo Roundball .22 Cal, 15.43 gr - 250 ct

Round ball in a airgun are going to be very hit and miss. The rifling twist rate in air guns are way to fast for round balls. Rifling twist rate for rifled muskets was 1 turn in 66 inches if I remember right. This was considered to be optimum twist rate for round balls at that time. The pellet rifles have a rifle twist rate around 1 in 16 or there about? Much to fast for round balls. Maybe if you had a variable pressure system on your pellet gun to play around with and try different speeds you might find a semi sweet spot for the round balls in the rifling twist rates for modern projectiles. Just my 2 cents worth on the round balls. I reload for powder cartridges and know a little about bullet weights and speed. Longer bullets prefer a faster twist rate than a shorter bullet. Then you have to find the speed at which that bullet prefers to fly in consideration with your gun. That's why you try many different pellet weights and such, to find out which your gun shoots the best.

Out of a 10 shot group I had a spread of 190+ fps. Group was 4"+ at 30 yards. I would never hunt with this ammo...

Pros
none

Cons
everything

My experience with these round balls was poor. I had high hopes for these but had difficulty putting them into the breech of my old RWS 52 side lever spring gun. They were too large to fit into it. Maybe being round balls, they were supposed to be tighter fitting. I was not comfortable cramming these in the breech. I ended up discarding them.

Pros
Reasonably priced to try in your gun. I would have given them to a friend if I had one who shot a pellet gun.

Cons
Found sizing to be in the upper limits of .22 caliber.

Least accurate I used out of a umarex octane , but honestly one of the most fun. This is the pellet you will use while messing around with your friends from the massive thump and power behind it.

Pros
Great for playing around

Cons
Not accurate for hunting past 20 yards

have serious knockdown for quick dispatch

Pros
hit super hard

Cons
pattern widens a bit

I* got these more for nostalga - used to use .22 roundballs in a Benjamin Pump when I was a kid. They work well in my Titan Nitro.

Pros
Accurate - tight groups on paper

Cons
but hits 3" right and about 1" high from zero using Crosman Premiers. Need to resight for any serious use.

The round balls have less deflection from wind .They still are heavy enough to be effective hunting ammo.

But at close range I can pop 3 balls in the barrel and shotgun a bird to bits

Pros
SHOTGUN

Cons
None at this moment

I was given a Benjamin air rifle that used the Roundball and spent months trying to find some to try it out. Works well in the gun but very expensive for both the quantity and shipping.

Pros
If this is what you need it works ok.

Cons
It is expensive

Long time waiting to get my hands on some lead BB's , well worth the wait. They fly true and hit hard ,and they don't bounce all over the place like steel BB's . Also I notice that these are nice and round not like some steel BB's that have a dimple and cause the BB to curve and miss the target. All in all a great investment and lots of fun. Thanks .

Pros
Nice and round ,Fly true and have more knockdown force. Great price .

Cons
none
