Cayugad - I have a friend (an mechanical engineer no less) who does the same thing. The only downside to this I have seen is that velocities run 100 fps or more slower than when fired through a clean dry bore.

setter77,any oil residue can cause this type of problem. Lee

I have not been oiling the barrel as I have been shooting it once or twice a week.

I foul my barrel with a small amount of powder and no bullet before the first shot. Simply point it upward andpop a cap. However, I use pryodex, and swab between each shot anyway, so after I foul it, I run a spit and dry patch down before I load for the first shot or go hunting. Pretty consistent for me.

I am having the same troubles.
First shot floats 8" high
then the rest are dead zero

Today shooting Black Mag 3 out of my White Ultra Mag .504 with 460 grain conicals and 70 grains of the BM3 powder, it was the first time my rifle shot to the same place at 50 yards on a clean barrel or fowled barrel. All I did was leave thecoating of Sheath in the bore of the barrel. I pushed a dry patch down to the bottom and popped one RWS #11 cap. It burned the patch good so I knew I had fire. From there I loaded and shot. All the hits were in the same place.

A lot depends upon the individual rifle and load so far as cold and clean impact vs a fouled barrel shot. Did a bit of testing just a couple of days ago to check my Ultra Mag's performance in that regard.

I had changed bullets from a 496 grainer down to a 460 grain Bull Shop so the scope needed some adjustment but...



all shots at 100 yards.

I also use Sheath it will put the frist shot in my gun to the point of aim with RS or with APP FF; I scrub till completely clean with hot soapy water wet a patch with Sheath and put a light coat on the boar,when ready to hunt I just load and go as I have tried this out at the range many times; remembering that each gun is an individual I would suggest that you do your own test to check what your gun does.
