Hey Nutz,
I've been coating rifle bullets with this stuff for about six years. It's a hobby for me so speed isn't necessarily a priority. I coat 308s for the most part in rifle. Running them at about 2600fps according to Lab Radar. Have pushed them over 2700 fps with no leading but they are not as accurate. I've pushed 223 and three coats over 3000fps with no leading. I have used Hi Tek on 223, 380, 45-70, 45 auto, 44 mag, 357 mag, 9mm and what ever else I cast. And by the way my sporterized .303 Enfield loves them. I don't shoot it much. Dad's old gun.
I started out putting three coats and still do on rifle bullets. My idea back when I started was to make a jacket out of it. But too thick is a mistake. It can cause flaking on smash test. Three thin coats are good and I have run one medium coat in the .308 with no leading. But recommendation is two to three. If your one of those guys that just has to have the color right it will take that many coats.
I use Lee sizing dies to put on my gas checks and have always been happy with them.
With all of the new casters coming after the recent ammo shortages I'll bet those lube sizers would bring a pretty penny on Ebay.
Good groups are not a problem with Hi Tek. Some use it in competition. The following are 308 five shot groups at 100 yards. My Marlin 45-70 will group 2-2 1/2" at 100 yards. 200 yard shots with 308 are in the 2-3" zone.
