Not sure if this should be posted here or the gunsmith section but hoping here will give me more in-sight.
As I posted yesterday in the "did you go shooting" thread, my Charter Arms Back Packer (3" ported barrel) was shooting 8" low at 15 yards. I shot the 20 round that I had with me and the load data is: 190 grn SWC, 7.6 Unique powder and est. velocity is 800 ft/sec.
All of the cases were very dark/dirty and again my guess is that the charge was too light to expand the case completely. Being a 3" barrel (with porting) I am thinking that I used as faster burning powder.Not sure it I want to step-up the charge above 800"/sec or have a little shaved off the front sight.
Any suggestion on this? BTW, I have a bunch of 190 grn lead bullets that I will be loading just to play around with,
