Hello guys and gals..(two alpha bullets) 180grtc with and w/o groove
got me some Super coat bullets that have a j&m specialty coating on a cast bullet. I forgot to ask him if their swagged or a typical commercial cast bullet? Just got them! Out of the ziplock bags they all seem ok..first time with a coated cast bullet..their are other types out there but this will be my first..purpose of the test is (for me) 3 reasons 1.leading 2. Accuracy 3.expansion..for me I would like to see some mushrooming..no ballistic gel here...just want to know if safe in a factory glock 20 barrel..and if their accurate. .if you all have any ideas or suggestions. .drop a line..one of my thoughts was to try shooting a string in a Barrel previously fired with jacked ammo..I will look for any coating during the seating/crimping process. .I post results with what worked best..what coated Company have you all tried? Results?

Sean, Welcome the forum!  many guys are having good success with the powder poly coated bullets which bakes on for a very durable finish when done correctly.  Temp and time are crucial for best results.

Many are even shooting theirs through rifles at velocities at and even above 2000 fps and recovered bullets still had their coating even in the engraved rifling grooves of recovered bullets.  They reported clean barrels and virtually no smoke as is typical with regular lubes.

Yes there are many using the coated bullets from Glock barrels.  Although I haven't started powder coating my own bullets, I am considering and gathering the stuff to coat my own cast bullets.

Best of luck with your testing and results! 

Working on the new place..and working off a phone..I still at this point have nothing but good things to say about the two alpha coated bullet. Accuracy is on par with jacketed..some inspection is in order..2 or 3 out of 100 might have a small chip out of the coating..they just work for me and my 2012 6.2in storm lake..thanks shadow. .sorry for delay in post..be safe..guess a blizzard is in route. .maybe that'll give me some shooting time?
