Out shooting my 3.75" Ruger Bisley in 45 Colt. A load which works well in my 5.5" Bisley and Winchester 1892 runs a healthy dose of H110, Starline cases and Fed 155 Gold Medal Match primers. The load came through for me, printing several 5-shot groups running sub 2" at 25 yds. It used to run smaller groups but my aging eyes and iron sights......
My concern is the horrible ES and SD. Even the good ones were running 151 ES and 46 SD. I figure if I had better neck tension/crimp that might bring my ES/SD down. I loaded this lot of ammo with the Redding Dual Carbide sizing die, Redding expander die measured at .447", Redding standard seater die and the Redding Profile Crimp die. My 285 gr LBT WFN bullets, 18 BHN using water cooled WW with a pinch of Tin measure .451" after lube/sizing with LBT blue lube. The measurements give me .004" neck tension which I assumed would be enough.
Your thoughts please?

Alan.... sounds like there is air space between powder and bullet. May be time to DEEP SEAT the cast bullet. With H110/296, I would start by deep seating over 20/H110 the 285 WFN. Suspect this arrangement may allow rROLL CRIMP on ogive. The deep seated bullet should hold PEAK rearward, which should shrink Extreme Spread, especially with sub-4” barrel. My preference would be to start with medium burn rate HS-6----also deep seated. "151 ES” is way out of line. Please report back.
Expect Lee may soon post Part 4 of my photo essay on Ronnie Wells brass grip frames. Includes photo of cast, powder coat 330-335 grain SWC deep seated in .45 Colt brass. A slight ripple can be seen of the brass case stretched over bullet. Powder is 10.9/HS-6 over the deep seated SWC. Plenty of neck tension. I expand case mouth just enough to start cast Plain Base bullet.
