In another post I was advised not to use Trail Boss (TB) in in old guns due to weaker metals used.
Checked with some reloading buddies and they all agreed.
So I’m researching my 32-20 load for a S&W 1902 revolver.
I have a Lee TL314-90-SWC if I powder coat I size them back to .314 if I tumble lube I load them as is. These Boolets will drop through the cylinder the bore slugs at .3135 to .3134
I went to Hodgdons reloading page and now I’m confused.
They list for 90g boolets
HP38 3.2g 11,900CUP 3.5g 16,000CUP
Titegroup. 3.0g 12,300CUP 3.4g 15,800CUP
Trail Boss. 2.5g. 11,400CUP 2.8g 13,900CUP
Trail Boss has the lower CUP. Am I misunderstanding CUP?
Looking at my reloading book
RCBS #1
Speer #10
Hornady #4
Hodgdon #’s 21 22 26
Lyman #’s 3 46
Only 3 listed loads for pistol (not contender or rifle) all were for HP-38
Other Powders I have on hand:
HP-38
Red Dot
Unique
Blue Dot
Thought about picking up a lb of Bulls Eye and I can get it locally.
It is $46 per lb while others are around $34.
I’ll buy it unless I have something that will work without putting too much pressure on the gun and still get fair accuracy.
This revolver left the factory around the end of 1904 and my Grandson was born the last part of 2004 (100 birth year revolver. I plan on passing it on to him and I want have a nice load to pass along with it.
Thanks
