These are a uniform traditional cast lead ball including the sprue stem from the mold. This can be placed facing forward or rearward, just like in a black powder firearm.
Things I would have changed:Maybe add a note or instruction so that people who have never used round ball, understand why the sprue stem is there.
What others should know:Round ball do not require a fast rate of twist to stabilize so slow twist barrels, smooth bores and lower velocities accurately shoot these balls. Higher velocities can be attained but then curve balling can occur. This can also be counteracted by going down a size. I use the 9mm balls in my Bulldog with great success at various velocities.

Things I would have changed:Smaller Diameter
What others should know:These do not fit in my AEA Terminator. The diameter is too large. The get stuck in the breach and or barrel. Several Airgun Blogs have reported the same issue with these in other Airguns. I have used a lot of other Senecal Slugs in the past and they work great. .357 Ammo appears to be in short supply now so I tried these. Thanks, Jim K.

Hi, could I shoot these ammo with a Benjamin Bulldog .357?
Yes.We do not know if the round balls will stay in the magazine.
WILL THESE ROUND BALLS FIT THE MAG OF THE HATSAN HERCULES BULLY 35/9MM WITHOUT FALLING OUT
No . round balls will not stay in magazines.
Can I shoot these with my Crosman .380 cal trapmaster 1100? Would I wrap the ball in a bit of cloth and load it into the pklastic shot shell? I was told that .375 cal balls was the ideal roundball to use but steel slingshot ammo that is 3/8" is the only ammo i've found here ...maybe i will have to settle on steel slingshot ammo.
Don't know about the Crossman Trapmaster, but your question about ball diameters caught my eye. The 0.375 ball diameter is what is used in the 36 caliber black powder revolvers. They are readily available anywhere that you can get black powder supplies and equipment. Hornady and Speer and Traditions all make swaged roundball in several sizes with 0.375 being just one. The 9mm roundball offered here isn't a size that is used with black powder, but if 0.375 is the size you need you can get them anywhere black powder supplies are sold.

As usual, super fast shipping
Things I would have changed:Don't advertise these as big bore air rifle balls. I'm sure they shoot accurately in a black powder rifle, but the sure don't in a big bore air rifle.
What others should know:I watched a you tube video stating that these balls were the most accurate thing they tested, so I thought I would give them a try. Waist of money. They won't hold a 5 inch group at 50 yards. They have a sprue and are not totally round. How can you expect them to be accurate? Some shooters said they sanded off the spue and that helped, but I'm not going to do that to 200 balls.
