Things I liked:I am using the Remington .22 Nitro Piston with these and after setting up the rifle for just this ammo, I can consistently shoot the grey bottle caps off of Diet Coke bottles at 50 yards, and with the same adjustment, I am shooting dimes and pennies at 25-50 yards. I just ordered 2000 more. Things I would have changed:Not really What others should know:If you set up your air rifle, or any rifle for that matter, stay with the same ammo to retain your accuracy. changing ammo means changing elevation and windage on your scope for crosshair re-centering unless you are used to mil-dot corrections for adjustment.
Things I liked:This is not a kids rifle and the word Magnum is in there for a reason. This thing is a hammer and there is always predictable accuracy with this weapon. Not that difficult to cock and the trigger is an absolute dream compared to all the others I've owned. Things I would have changed:The scope is not even worth thinking about putting on. Go to you big box store and get a notable name brand 3x9x50 and be done with it. My scope cost $40 on sale and it's .30cal rated. No worries. This thing is heavy to pack around, sling swivels would have been nice. The manufacturer should have used better grade grease or none at all would have been nicer and all the connections including scope mount were barely hand tight and now I'll tell you how to make this thing a 50yd tack driver.... What others should know:Take off the scope mount, clean threads, put on and tighten with a dose of loctite 271. This thing will test your mounts. Get a screwdriver, take off the stock and clean every ounce of that black crap grease, and use a good white lithium or thick graphite for all moving points. Clean barrel with NO CHEMICALS, just swabs then when that looks clean, get a nylon bore-brush and do it some more. Now, mount your scope, took me 5 yards to zero at 20 yards and my 50 yard shots are only a 1-mil up hold. Clean with clean brush ever 20 shots through your first hundred and after that, re-check your zero on the 10 ring 1" targets at 25 yards. I get 1/4" or less grouping and the RWS 14gr pellets are penetrating the 1-1/2" back board. At 25 to 37 yards I can hit a dime or split a cigarette on a dead hold. I put a piece of wing walk on each side of fore-stock to increase grip when using a tree or other item to steady shot. This is a real weapon, not a toy, every kill on this has been single shot, no run or fly aways and it will split a snakes head in half from 50ft(but that's another story). The more expensive nicer grade pellet guns are great, I will buy one, a very nice gasser maybe, but this one is my trusty pocket knife that I can count on every time. Be sure to re-zero every 100 or so shots, keep your barrel clean and little to no oil for consistency. Most pellets come oiled, just keep that in mind. Heavier pellets work better and keep all connections tight. I Love This Rifle!
