44-77 brass

[J.B.]

This may be old news to some but having recently gone to place an order with BACo for Captech/Jamison 44/77 brass, I noticed that the listing for cases to suit Shiloh had been dropped from the range. Was there a few weeks ago but not now. A few emails to and fro to BACo established that the Captech rim thickness of .072" was apparently still too thin to be ideal in the Shiloh action. I believe this was confirmed between Shiloh and BACo and a figure of .076" would be almost ideal for that Shiloh chambering. Certainly this has been my experience and when I ordered some RMC brass I stipulated rims at .076-.0765". When they arrived..they were a perfect fit. Some came to .077" on my verniers but the breech still closed..although it did barely touch the case base. No marks though.
Back to the topic... BACo are apparently ordering the brass and have a method to bring the rim thickness up to approximately .076". There will be a delay obviously until there are stocks and a slight increase in price as additional labour is involved . The cases listed now with .072" rims and .012" necks wouldn't work in my rifle unless I go to paper patching. My chamber is too snug for necks thicker than .0105/.011.
I purchased about 250 Jamison cases from their first re run and while the rims were a tad thin at .0715-.0725" ..they were..or seemed to be working. I figured on fire forming that the headspace issue would be gone as I was only sizing necks. Have any others had any issues. ?
