.22 H&N Field Target Trophy 14.66gr

What about JSB Jumbo 15.89 gr, JSB Jumbo Heavy 18.13 gr and H&N Baracudas 21 gr or Crosman Premier Hollow Points 14.3 gr? My Walther hates the FTTs but it loves 16 gr Polymags, 15.89 gr JSB Jumbo in 5.51 and 18.13 gr JSB Jumbo Heavy in 5.52... got a Chinese SPA p900w on the way which will arrive tomorrow or on Monday. I´m curious which pellets it will like. For the price of the airgun, I simply had to buy it. A .22 PCP with a 7 shot magazine for 200 bucks... WTF. Even if the gun is poop it will be sufficient for plinking but the reviews weren´t bad at all.
