Hey Guys,
I have a question about lube coming off cast bullets. I'm currently reloading .45 Colt with Unique powder & SNS cast bullets that have the blue lube strips at the bottom of the bullet. I make my target loads so they chrono out of my 5.5" SAA clone at around 865-880 fps at the muzzle. I've noticed that at the start of shooting I get good accuracy out of them, but by the time I get to 40-50 shots groups are opening up and the number of fliers increase. By this point, the gun has usually heated up considerably, to where I can feel heat on the top strap of the frame. it is usually at this point that I will notice pieces of the blue lube strips on the target as well.
My question is, does the heat from the barrel and cylander cause these lube strips to melt and/or shear off and create tumbling, either in the barrel or in flight? Aside from letting the barrel cool off, do you have any recommendations for preventing this?
As always, thanks for your time and insight.
