I got my Sass new model Vaquero 45 Colts back from Boomstick Jay and took them to the range yesterday with my Athlon Chronograph. It was a very breezy 75 degree day. American Cowboy OEM 180grn 506fps, 91 PF with a Std dev of 24.0 (15 rounds 165grn home cast/PC Lee RNFP & 3.9grns of TiteGroup, w/ Fed LP primers 1.097” OAL 608fps, PF 100.3, SD 25.0 (20 rnds) min/max fps 537:641 130grn Barnstormer, 3.6gr TiteGroup w/ Fed LP Primers, 1.0685” OAL 602fps, 78PF, std dev 41 (35 rnds) Min/max fps: 447/653 I load on a XL650 and my powder measure is very consistent rarely varying more than 0.1 grain but I’m guessing that is the likely cause for the large Std Dev on the Barnstormers. I loaded a hundred rounds and randomly grabbed a handful for this test. I’ll have to repeat this test but will likely increase my load to 3.8grns as the PF is too low and a number of rounds had un-burned green powder residue. FWIW I DO perform test weights about every 10-15 rounds and do more frequently if I find variance.

Somebody tipped me off to this cool little jig that allows you to effortlessly cut down .45 Colt cases to use in loading Cowboy 45 Special cases. it works with the Harbor Freight mini Chop Saw. It has some adjustment, I settled on 0.900-0.906” and then used my Lee Quick Trimmer on my Single stage press to do the final trim, deburr and chamfer. i was able to convert 50 cases in about an hour. https://ebay.us/m/4IABUu
