Just an update on that BSA.  The accuracy is great.  I tested the power today.  The test is a bit relative. I used these really hard green oranges off of my tree and lined then up 3 deep. 
 If  I pump my .177 Crosman 10 times it will penetrate 1 green orange come out the other side and make it half way through the 2nd orange with a pellet.  When I shoot the new BSA in 22 cal it will clear 2 green oranges and half way through the 3rd.  I repeated this test a few times with repeating results.  ( I know not very scientific but relative).  A .22 is only .043 larger than a .177 but the hole looks completely different.  The .177 hole was hard to find on the skin.  The .22 hole was easy to find on the way in and a good chunk on the way out.  I think this satisfies me to give it a try on small yard game.
