Boy if I poured them out of the mixing bowl any sooner then the bullet coating drips all over the place. The mixing container residue is still plenty runny when I pour out the bullets now. I can guaranty you that they are not too dry when poured out. they actually look really wet and shiny. Once the solvent evaporates they get a bit of a rough surface. Maybe it is just this color. Has anybody else used this Red Copper and have some good up close pictures of the finish product. All these pictures were taken after they were sized after final coat.
The bullet speed coming out of the barrel that has enough energy to cycle the action is between 950 and 970 fps. I really don't see how moving the bullet any faster will prevent the coating from coming off where the lands are riding the bullet. If anything, increasing the velocity will only create more friction and heat where the lead is exposed and melt more lead to the barrel.
"That bore part of the coating should show wear"
I don't thing that is entirely true. If this coating is doing what it is supposed to do, than little wear should be showing on the whole bullet. Here is a bullet captured that was shot at a velocity to low to cycle the action. I don't know how slow as I was shooting it into the bullet catcher and not over the chrony.
Notice that the coating under the land on this bullet shows very little wear also. It is clearly imprinted by the land but the coating under the land is very similar looking to the coating under the groove portion in the other bullet portion.
High pressure, low pressure...I would assume the if the bullet has a good gas seal, high or low pressure, and no gasses are coming around the base, that the coating should stick and deform with the bullet at the velocities I am pushing them. The ramp into the lands looks smooth enough to not cut the coating off. It appears as though friction is removing the coating from these bullets as all the fired bullets show above are fired from the same barrel just at different velocities. The bullet showing gas checking was a softer alloy bullet that skidded and did not have a good gas seal.
