Things I liked:light and lubricates between the piston seal and the chamber well. It smells like it has hydrocarbon products (petroleum) in it. It does diesel occasionally in my RWS 34 panther but not bad at all.
Things I liked:This gun in .177 has excellent metal parts and is very solidly built. The rear sight is all metal. The front fiberoptic red dot is also quite clear. The trigger is clean and very crisp. The gun is more accurate than I can shoot at the offhand position with the iron sights, because I can tell instantly where my pellet is going to land after pulling the trigger. After about 100 shots it is more or less "broken-in", with smooth cocking and firing. Things I would have changed:It is definitely muzzle heavy. Because of the straight style of the stock, I found the standing offhand position most comfortable for the iron sights, but sitting position is impossible without a scope. What others should know:I shoot only non-lead pellets, which means Crosman, Gamo PBA or Skenco. The Crosman and PBA pellets are too light for this gun. The Skenco golden rod pellets work well in my gun.
Things I liked:Cheap for lead-free pellets. Things I would have changed:It is too light for medium powered rifles. The pellets leave large amounts of residual powder on my fingers and in the barrel. What others should know:You definitely need to clean the barrel of your gun frequently with these pellets.
Things I liked:Works well in my RWS 34 panther. Things I would have changed:The price! Have 250 or 500 count tins and lower the price. What others should know:With my RWS 34 panther factory gun, these pellets can puncture my Beeman metal pellet trap if I don't use duck seal to stop them.
