thanks ,i have some time i did not read charles mellons front page my parts are not due probably for another 3 weeks he is swamped. i already have his stuff on my pcp's so its worth the wait i just hate doing it. Can i get 650fps in 22 14 grn with his flat top set up if i put a 14" barrel and steel breech? I am at a crossroads at since i have time need to know which tko to order 177 or 22 same with barrel and breech. was thinking 177 originally but then i thought i saw some of the modded 1322/pc22's hitting the 650 mark in 22 this would do a better job on cali ground squirrels. any input is appreciated since i have a lull in this build and i need to sell a winchester/daisey 1000 springer to finish
