I ran a series of tests on FrogLube to see if it had any effect on the bore of a muzzleloading rifle and to see if it did anything to help keep the bore clean. I used a chronograph to measure the velocity of the patched round balls from both an untreated and a FrogLube treated bore on the same rifle. I found a statistically significant difference in muzzle velocities which told me that FrogLube does, in fact, condition the bore of a muzzleloading rifle.
When the group sizes from the unconditioned bore and the FrogLube conditioned bore were compared, there was a statistically smaller group from the FrogLube conditioned bore.
While shooting, I wiped my bore between each shot and compared the patches from the unconditioned bore to those from the FrogLube conditioned bore and found that the patches from the FrogLube conditioned bore had removed more fouling indicating that the FrogLube conditioned bore more readily released the fouling and it was more easily removed.
After cleaning my bore thoroughly, I ran a patch with FrogLube on it down my bore to protect it from rusting. After one day, no rust was found in the bore. After 5 days, no rust was found in the bore. After 2 weeks, no rust was found in the bore. My conclusion, simply stated, is that FrogLube does just what is says it will do.
