When I bought one of the BF pistols about 10 years ago, he was using Bullberry. I have several BB barels and they have all been outstanding shooters, not just very good. All were well under moa for four, 5-shot group aggs. The .25 Bullberry and the .300 Savage were between .5 and .7 moa aggs with their best loads. The BF pistol in .25-20 is a real shooter too.
