I used to shoot the T7 pellets and then loose out of my Pro Hunter. I had to swab between evry shot for just the reason of getting another load into the barrel. It did not make shooting very fun. I am now shooting BH209 and having fun. I can shoot 20-30 times w.out swabbing and am very pleased w/ performance not to mention the clean up ease! Some on here have had good luck w/ T7, but I will not go back ever since i have been shooting BH209. I do not care what it costs!
