I'm obliged to:
CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The High Road, nor the staff of THR assume any liability for any damage or injury resulting from use of this information.
I've had some strange results with W296 and 255 Gr. LSWC bullets, in a 5.5" Ruger Blackhawk 45 Colt. Usually gas blow-by making black marks down the cases, sometimes powder grains in the action and chamber.
I started at 21.5 Grains and worked up by .2 gr to 23 gr. I've seen load data posted that far exceeds these charges, and also seen the warnings about backing w296/h110 off too far, so I'm not sure what to do now.
WW brass, CCI or Fed Large pistol primers, temperatures around 50deg F. Velocity is eratic over the Chronograph (1000-1180 fps 5 shot string), with the cases that suffer bad blow-by loosing A LOT of fps. Cases drop out when not dirtied by blow-by, primers not cratered, not flat etc. Headstamps look fine.
Does this sound like inconsistent ignition? If so what practices are recommended to prevent it?
I would like to do further development and post results, and I can post a picture of stained cases, or if you want to see the crimp, iw ill do it.
This is my first revolver, so I'm just not in my comfort zone. Is this blow by normal? Will raising the charges, or heavier bullet, or better crimp create a better seal in the chamber.
Thank you.
