I retested some loads because I wanted to see what would happen, if anything if I crimped with a lee fcd after seating the bullets.

Always interesting to see real world chrono results. Thanks for that. Gotta get me some BE-86 to play with.

I used to love the Remington SJHP 140 .357 mag load. Seemed like a great balance. I still have a little of it, and the Federal version, left.

Found a comfortable load for my 360 PD that shoots to POA at 25 yds. Carry this gun in my rain coat pocket when walking the dog in wet weather. Carry three rounds of the 125 followed by two of the 185gr LFNGC (which chrono at a bit over 1,000 fps from the 360). Haven't chronoed the 7.0gr BE86/125gr but guess it's 1,000 fps or a little less. The laser is now adjusted to POI at 25 yds with the 125s.
