I made some Emmerts lube about 3 years ago and have been using it as my only bullet lube since. I use it with both Black Powder O.E. and Smokeless CFE-Pistol in 45 Colt cartridges.
I believe I have been experiencing lube purge flyers after my initial 5 shots.
The first 5 shots my Lyman 452664 bullets make a nice tight group, bullet holes touching at 50 yds. With smokeless by shot #7 the 24” barrel is quite warmed up from breach to muzzle and the shots won’t hold in a tight any more the groups group spreads 6”. The lube purged shots seem to land the furthest out from the POA blowing the group to an inflated 6”.
With Black Powder O.E. 35 grs 2 fg the group holds tighter then throw a flyer then back to tight grouping again until the barrel pukes the next flyer.
I’m think my Emmerts needs an ingredient added to raise its operating temperature or to stiffen it up for hot weather and hot barrel usage.
I have Carnauba wax flakes.
I thought about adding candle wax the type that has stearic acid.
Or maybe Vybar 103 to help hold the oil or raise the melting temperature for summer time use.
I remember in August the rifle barrel laying in the hot sun was too hot to touch for 1 second and I hadn’t fired my first shot yet.
