Hi Guys,
Working on a little development and was trying some Accurate Arm No #9 for a brisk load in my Henry .44 and 629PC. All the manuals show 16.2 grains of AA#9 as bit below starting charge for for 240gr LRN-FP.
Well in my 629PC... 16.2 grains of AA#9 runs a 240 LRN at snappy 1165 fps across the Chrony
But....in my Henry .44 rifle the same 16.2 grs of No 9 with a 240 LRN-FP is at 1442 fps which is a bit to fast for my liking, I ran 25 rounds through it and had no leading....but my alloy runs 13-15 BHN, so I need to back down to 1250-1300 fps to not push the limits too hard with my cast bullets(no gas checks here)
Anyone running No 9 with 14-15 grain charge?? Curious about your velocities
I have No. 5, and No 7 on hand(not enough) ....but I have much more No 9 so I'm trying to work up a "warm" load with No 9. But not too warm :)
thanks
