I have a Gamo Swarm Magnum in .177. I have used the Crosman .177 hollow point pellets in several of my air guns for years; a matter of price and convenience of being able to purchase almost anywhere and anytime. However, the GSM puts them out at over the speed of sound so the sound was much like a .22 LR (even with the Gamo suppressor). I had neighbors somewhat close and did not want them to be upset, thinking I was shooting an actual firearm in the back yard. I purchased the Crosman 10.7s specifically to slow down the muzzle velocity. These do the trick (muzzle velocity dropped to under 1,000 fps.).
Things I would have changed:Nothing.
What others should know:Changing from the 8.3 gr. To the 10.7 gr. dropped the point of impact about 6 inches at 25 yds. I had to resight the gun. These group at 1/2 to 3/4 inch at 25 yds.

Will these fit in the Gamo Swarm Whisper? I know that piranha pellets will not and I wanted to make sure these would or would not.
These obviously weigh and look the same in the pictures as the Premier Heavy 10.5 grain box of 1250 pellet but are they really the same pellets? Facts only please.
They are the same. Woodys World.
Does this fit in the umarex SA10
Its It is a CO2 BB/Pellet pistol with a maximum velocity of 420 fps. Why would you want to shoot a 10.5 grain heavy .177 pellet. It will eat up all that velocity. It will not have 420 fps shooting that, more like 200 fps. You would do a lot better shooting 6-7 grain lite pellets.
Yes.

Great pellet for the price; very little difference in accuracy compared to more expensive brands in all my PCP rifles as long as the velocity is kept between 800 to 890 FPS. They are great to use for tunning your rifle and plotting a power curve due to their low cost.
Things I would have changed:I would not change anything because it would probably make them more expensive.
What others should know:Seems like they are easier to find in stock than most of the expensive brands.
