842 Ft/sec
5 Stars
842 Ft/sec
This rifle is very well made, a bit heavy. I have found it very accurate with both the stock sights and a Pinty scope. Using my calibrated Chronograph I measured a consistent 816-842 Ft/sec on a new cartridge. This is also using a 12gm cartridge adapter. I use my pellet guns for a squirrel problem and shoot perhaps six rounds at a time. A 90gm bottle would probably leak down between sessions, the 12gm is perfect. The 30 round belt is super smooth and consistent, no jams.Update, I definitely got a good one, it has just gotten stronger and faster. I now have perhaps a dozen cartridges through and with a brand new cartridge, Crosman Destroyer pellet check out the first shot through the chronograph.Update for a jam. I have had one jam and it is my fault. The cartridge can be put in just short of the end and will hold in place, when fired the pellet will not exit but will protrude just enough to lock the cartridge. The fix it to use a rod and push the pellet back and that will release the cartridge. The solution is to be sure to full seat the cartridge other than that this thing has been amazing.
