.38-55 seating depth

[zipdog]

Is anyone out there using the Old West .378-270gr? If so, how deep are you seating the boolit?

I don't use that bullet but I do shoot a 275 grain LBT out of a Marlin 93 Custom gun. I use starline long 33-55 brass. I seat the bullet as long as possible that feeds everytime. I use a lee collet die to just take out the bell in the case. Preliminary testing keeps 5 shots in 1-1/2 inches at 100 yds. open sights. 1600 fps range, sometimes a bit more. I'll work on it some more and shoot 10 shot groups now but if it doesn't improve on that...good enough.
