I picked up two .177 LW barrels with 1 in 27 twist poly profile rifling. In my experimenting so far they are looking very good. I seem to get the best results with JSB 13.4gr but the JSB 10.3’s also shoot very well. In my last USARB 25m match I had a high target of 249-9x in rather windy conditions which was well above my expectations. To early to say for sure but as of now I like the “slow poly” barrels.
