Interesting Seafire,I tried Benchmark and a 139 gr BTSP Hornady in my Featherweight for my daughter to use this fall. Over the chronograph it's a getting a whoppin' 2480 fps average. The accuracy is about one inch +/- at 100 yds. So,when we get it sighted in for her and the groups are bigger,it's not the rifle,scope or load.
Have 500 of those bullets,so she has plenty for practicing.
