Beating a dying horse again.
Agree that chainfires from the front will not happen if your using a correctly oversize, soft lead projectile.
Most dissastisfaction from using Criso over the top is due to applying too much. General guidance for applying instructs you to fill to the top with lube. This is way too much for proper lubrication. I only apply a small puddle to each chamber. I also use a small spreader to spread it around over the projectile. This increases surface tension, which prevents it from running out of the chambers and/or into your holster. Using a small amount of lube also greatly reduces lube splattered onto the barrel...barely any on my holster-sized revolvers & zero on my Dragoons.
For those who insist on generous lubing, I suggest Criso in cooler weather and Criso melted/mixed with a small amount of beeswax in warm-hot weather. Note you may have to apply this stiffer lube with a makeshift spatula...remember, it isn't gonna "flow".
