Hatsan Flash .22 and amo selection

My FlashPup liked 6 type and brands. Crossman Pointed 14gr,, AirArms 16 & 18 with the 18 being better,,H&N Coppa-Spitzkugal 16gr,,H&N Barracuda Match 21gr,,JSB ExJum RS 13.4 gr. the JSBRS 13.4gr and the AirArms 18gr were the best in mine. 1/4 and 3/8ths 5 shot groups at 25 yds. They all will take out any of the animals your looking at.
 
My Flash .22 likes the JSB 18g and 25g pellets. I've had pretty good luck with the H&N slugs. I ordered the sampler pack in .218 cal, and it liked the 25g slugs the best. This is over short distances, about 15 yards. I haven't had a chance to get out and shoot over longer distances yet. I just received a pack of FX slugs the other day, but haven't had a chance to shoot them yet.
