I bought some of the Gamo .22 rounds for a pistol I'm working on, has a magazine feed so needed the round loads for it. A murder of Crows flew into the yard and were sitting in the trees making a racket so I grabbed a B-26 and stuffed one in, hit the Crow right in the chest where I was aiming at about 20 to 25 yards and knocked him right out of the tree, never moved after he was hit. I've had some good hits on Crows and had them fly off so was real happy with the result. It was the last day of Crow season so finished it with at least one in the bag. The rounds may not be the most accurate but they sure penetrate good, tried a few on the Grackles moving through and you can tell by the thump when you hit them, they drop and don't even flutter on the way down....

nice to know thanks for the tip

Hey Mike, I have a Benjamin 422 semi I got in the '60s I always shot 22 pellets but was reading somewhere that it may shoot round balls?? Know anything about that? By the way the B40 is shootn good. 1" out to 40 yds. Randy

very interesting indeed. I will have to check em out:) Thanks , Tony.
-
I might be wrong but I think round balls weigh a bit more than waisted pellets.
-
The ones I have from Gamo are 14 gr., they are more dense than the pellets becauase there is not hollow skirt in them. In penetration tests they do better than pellets, just aren't quite as accurate.....
-
I have no clue if it will shoot the round balls, check the owners manual at Crosman, it may tell you if it does or not.....

Very interesting observation. Mike, are the .22 B-26 barrels generallytighter in the breech area ? I also have a couple tins of the Beeman perfect rounds in .177 from a few years ago. Mostly they will just roll out the barrel or roll in to far in the breech of guns I've tried them in. They don't recomend these for springers, but I do have one .177 QB-57 with a tight breech , that they will work in. They give me 1" groups at 10 to 15 yards. Also have been using them up in the Crosman 357 CO2 revolver. I've been meaning to try the .22 Gamo rounds in the 2240's, and Benji 392 now that they have become available again. A poster over on the Green forum posted that he uses them with good results out to twenty -five yards. If they made the .177 rounds the same size as the original lead BBs , .175 dia. , instead of .173, they would seal better and work in more guns. They also seem to me to be really expensive for what they are. Almost bought a CO2 Shark pump in .22. That would make a super rat buster!

The rounds fit snugly when loaded, at 20 yards groups of under one inch are common with the rifle I am using.....

There are a few forces acting on a sphere that is spinning "rifleing"
at speed..diffrent pressure zone on each side....for a short shot they are ok
but the longer they are in flight the stronger these forces be come...
till they get to a stage where the sphere "BB' gets pushed into the low
pressure zone on one side by the high pressure zone on the oppisite side.
These forces are how a tennis player makes the ball drop "top spin"
A base ball pitcher turns the ball in the air...
why a golf ball curves after hit.....and so on...
If yer want to know all the ins & outs of spinning sphere traveling at speed...
Google the ....MAGNUS EFFECT
-
at longer ranges it will shoot rounds around corners as the velocity drops, just like a good curveball........

I guess that explains why I've always gotten better long range accuracy with round balls shot from a smoothbore, than a rifled bore.
BTW, size F lead shot is .220 diameter. $42.99 for an 8 pound jar from Midway USA. Could go in with a few others to split it and keep the cost down. Would be a little over 5 dollars a pound plus shipping.
#3 lead shot is .250 diameter and is $24.49 for a 5 pound box. Great for a .25 cal.
