I'll give you some feed back on rifles.
I have shot Hi Tek coated bullets in .223, .308, .44 and now in 45-70 rifles. All except the .44 were shot at targets 100 yards away.
Your first point of interest as far as lubricant in rifles is the lubricant running out before the bullet reaches the end of the barrel. Properly applied Hi Tek does not do this when all other considerations with casting and reloading are taken care of.
The next thing is if accuracy can be maintained using the Hi Tek. I have one five shot group out of the .308, if you discount a flyer that made it close to 2", that was under an inch using Hi Tek. That's four shots under an inch. Repeatable five shot groups are 1 1/2" in the .223 and .308 at 100 yards. Some will argue the point but, anything grouping three inches and under is good enough to hunt with. The only time I wasn't able to achieve groups out of my rifles that grouped 3" or under (the majority under 2") was when I did not adhere to some other requirement of reloading or was using iron sights. On the last one that's probably me not the gun, round or the Hi Tek. Would be happy to supply some photos as I have done with some of my post. Here is the under an inch group of four.

Another consideration is cleanliness of the barrel after use. I also have had the experience of firing Hi Tek in my rifles and the barrel looks clean and shiny. It doesn't happen all the time but most of it is powder residue when it's dirty. On this note, I agree with Trevor that the Gold 1035 is excellent. Still using the first batch of liquid Gold 1035 I bought when I started three years ago. I know we have said it countless times but, this stuff goes a long way.
I have only two minor complaints. The first is not very significant. With some of the powder coatings I have used there will be a small mount of color come off during the rub test for curing, even though they are properly cured. Trevor said something about a little too much color in some of the powders. In any case, these bullets will deposit some of that color in the rifle barrel which cleans right out with wet and dry patches. It is not a hard deposit like some have gotten shooting improperly cured bullets. More like powder residue. The second complaint is one that I know your working on . I still don't have the Auburn University colors orange and blue so I can irritate the Alabama fans at the shooting range.
I would not call myself a professional caster coater but over all Hi Tek has been an enjoyable addition to my casting, loading and shooting hobby. And I appreciate you Aussies sharing it with us.
