I am setting up to load for a marlin .44 with 1-38 twist, 16.5" barrel with suppressor. I am hoping to use a reasonably heavy bullet (ideally Roberts 280 grain lead bullet) at about 1050 fps, but am concerned about bullet stability especially regarding the possibility of suppressor strike. I have run some of the heavy weights through JBM s calculations and the they show the 280 and 300 gr bullets to be marginally stable.(280 gr gives a stability number 1.260. Site says they should be between 1.3-2 ) Im not sure how these numbers translate to real world but would I be right to worry about shooting these through a suppressor? I have read I should test with suppressor off (then check target for round holes) but is this a reliable way to check for stability? Is a projectile more or less stable as it immediately leaves the barrel or does it tend to stabilise or destabilise over distance? If a bullet tends to stabilise over distance, maybe checking for round holes doesn't guarantee it wont hit the suppressor. I might be over thinking things but I hate that feeling that I haven't thought things through before I pull the trigger. Has anyone had a play with a similar type of set up?
