I hastily cast a small batch of these (penta & large HP pins) late Tuesday night of ACWW. Lubed them Wednesday after work and loaded them over 9.5 grs. of Unique. Chrono results as fired from my 4 5/8" NM Vaquero are:
Large HP (265 grs.)- 1034 fps; e.s.- 20 fps
Penta HP (276 grs.)- 1000 fps; e.s.- 18 fps
Unlike my Uberti's which seem to have become a natural extension of my arm, I struggle a bit shooting this Vaquero effectively. I tried to get some groups at 25 yds. shooting from the bench, but I have a difficult maintaining a consistent grip shooting from the bench as evidenced by groups with 3 or 4 shots clustered together, with 1 or 2 out of the group. I finally hung a target on my 50 yd. board and shot from a sitting position which seems to work better for some reason:
Tomorrow night I intend to cast a full pots worth in non-HP form and try them Friday after work.
