Have been looking for 348 AT and /or 405 At. Can find 348 at Cabela`s but no 405. Got last 348 from Gunbroker but none on there now. Used 2 packs of 348 & finally was able to get 3 holes in the paper at 100 yds. Have tried Pyro RS,BH209,T-7 from 80 gr to 100 gr. Shooting Omega so that is no doubt the problem. Running out of time so don`t have time for new gun. Looked at the Lyman break over. Nice gun but may not have enough time. Any ideas? Thanks
