Have .177's, 22's, and 25 cal air guns. The 25 cal PCP,s (pre charged pneumatics) that are charged with a scuba bottle are very powerful. The German 31gr lead pellets are coming out almost 900fps. I have taken out big boar raccoons with the H&N .25 cal pellets. Lots to consider when making an air gun purchase. I like the fact that they take no primers at $ .10 each and powder at $30/ lb to have fun shooting. Pellets both .177 and .22 are cheap at the Wally Mart! Another consideration!
