Question: Is there a way to control the pellet velocity on this rifle.
Document: this pcp air rifle is light weight accurate easy to operate and over all a good value for the dollar. The only downside is very high noise level of the shot. It makes it questionable for pest control
This rifle is very accurate when you find the compatible pellet. I like the fact that it has no recoil when shooting. I also like the fact that the air pump was included. I actually prefer using the pump so that I dont accidentally overfill.
I thought this pcp rifle was a bit overpriced, but given store prices on low end .22 powder rifles it isn't so out of line. The pellets are currently very inexpensive (~$8/500) compared to firearm ammo, and pumped to 2,000 psi with air, this thing packs a dang good pop (a pellet will embed a half inch into hard pine at 40 yards).
I enjoy target shooting so this rifle is a real hoot! If you like to "break" targets, clay birds will shatter at 50 yards with this airgun. Plinking steel targets like discs or a shooting gallery will not result in much sound or movement, although are easy to hit. Each pellet weighs 14.4 grains and doesn't have sufficient momentum to move metal at 50 yards!Some users have complained about the trigger being spongy with a "high" pull weight.
first impressions. Most powerful air rifle I have ever owned. About 20 foot pounds from the muzzle. most springers are about 15 foot pounds. In .22 this is a beast, shoots a 14grain pellet at about 840 fps. LOUD, too loud for neigborhood use, unless you buy a TKO silencer for $44. GREAT air rifle. Takes 100 pumps to get to empty to full, 50 pumps from 1000psi -2000psi. LOVE IT, BUY IT YOU WON'T BE DISSAPOINTED.---- NICK
Also they told me to call Sun Optics about the gauge on the pump.The reason I bought this gun in stead of a Korean one, is because it is made in America, don't go by that!!! !I have tried over 12 different types of pellets and can not get it to shoot as accurate as my Benjamin Trail All Weather at 40 yards. By the way, my Benjamin Trail is from China. Both guns are 22 cal.
Only gets hard when you get real close to 2k PSI. Figure it will take about 30 minute to go from 0-2k. Once you've filled it once, don't let it drop below 1k for sure, I usually refill at ~1200. Only takes 5-10 minutes that way.- Trigger is fine for a gun in the price range.CONS:- The only con I can think of, that is not something that is already advertised with the gun, is that it is LOUD.
As far as accuracy, you can dial this thing in really tight, especially if you are shooting braced. Even shooting free hand I do better than with my powder 22. I have no doubt that the reports in these reviews of hitting nickles and wooden coins multiple times at good distances are not inflated. This is a serious small game hunting gun or varmint control tool. You could do far worse than shoot your eye out with it, Ralphy.
With 22 caliber pellets and around 40 F outside temperature, I get about 15-20 shots before pellet slow down necessitates a refill (shooting at 50 yards).
I have a Ruger Blackhawk Elite that I bought from WalMart that shoots 1200 fps, but it is nowhere as accurate as the Discovery. I actually shoot into the same pellet hole with this gun, it is that accurate. Very tight groupings and that is just using the Crosman Premier pellets that you can buy from WalMart. Get one of these today, and don't listen to the people that say the gun is too hard to pump up by hand with the pump.
Answer: yes
