I load Missouri coated bullets in .357 and .45 Colt Henry rifle, both with 20" barrels. I've not seen any coating residue left behind. in my .357, I'm using a 180gr rnfp with 11.5gr 2400 @ 1400 fps mv. with 158gr rnfp's, its 13.0-13.5gr 2400 @ around 1550-1600 fps mv. .45 Colt gets rnfp 250gr/8.5gr Unique @ about 1,000 fps mv. Hope this helps.
I talked Acme Bullet company into sending me a sample pack (5 bullets) in 30 Caliber to try in one of my 30-06's. These were their "Lipstick" bullets. They were 220 gr. and I kept the velocity in the 2000 fps. range. I noticed no residue left in the barrel, but I had a limited sample size...but decent velocities.
I just looked at their site and it seems that their variety is not what it was from a few years ago. Maybe Pandemic related.
I use the MBC projectiles in 44 cal and pushd them to 1,467fps so far and 1,398 fps in the 460S&W with no issues. I haven't seen any of the coating sticking to the barrel. They just work really well. I like the Brazos Precision Hi Tek bullets in 10mm as well.
