The Sumatra is a .22 cal which I am not running at full power. Still it's running over a 1000ft/sec with 28.4 gr Eujin pellets, and at the 70+ or 24 yards it looks like the pellets are hitting straight on. No crack so I am still below sonic. but it's loud. Need to set it up a little slower and quieter. Sure we can get together sometime here or there. Let me know when you might be down this way. No problem if you don't bring one of yours. Besides the Meteor I have a S1K, Varmit Hunter in .177, and a CFX in .22 along with a B3, Lighting XL .22, and a 350 .177. At least I am hoping when I get new neighbors they will be okay with my shooting, the house next door went up for sale this last week. Any airgunners in Wichita want to move next door? Have a measured 24 yards set up in my yard and for longer ranges I move out into a wheat field next to me after harvest. When I bought the Sumatra I wanted a .25 cal, but all Tim had at he show was a .22. Been looking at those large bores and met a fellow named Leroy from here that makes a .45 cal. His lowest price is like a $1,000 and like Dennis there is a backlog for his guns.
