I don't see enough difference to matter.

That 416 load is very good very low extreme spread.

Was there any leading from the lubed bullets.

no, no leading at the velocity with lubed bullets...but at higher vel the leading is copious

That has been my experience also.

I need to try some coated ones in my 460 and 45-70

What is the best solvent to clean lead from the barrel ? What brushes ?

I always just used hopes and a brass brush could be better things out there.

I see Brownells still has the Lewis lead remover it works well also.

Now that I shoot all hard cast at under 1500fps velocities. I have very little leading to deal with and I keep on top of it.

just fire a jacketed bullet...cleans everything

For pistols and revolvers I used an impreganted yellow cloth. I think Kleen Bore "Leadaway"? A very small strip seemed, almost, to "grip" the barrel lead. I've no idea what it was made from. But it worked excellently.

Sounds like what I used to use when I was shooting soft lead through my .357 mag.

It removes the lead alright but I think it might be a bit harsh on the bore. If I put a piece of that through a clean bore it always comes out black, which tells me it's taking metal out of the bore. Prolonged use could smooth out the edges of the lands. Not sure if that's a good thing.

Get some of the Chore Boy or Chore Girl copper scrub pads or some of the course bronze wool from Brownells and wrap some in a bore brush. A few passes and you won't have any lead in your barrel.

Thanks . I'm beginning my adventures in bullet casting soon . It will be interesting.

Gents:
I have cast and am powder coating now and will shoot this spring the following calibers:
4-bore 1900 grain conical
4-bore 1400 grain ball
8-bore 1620 grain conical
8-bore 1000 grain ball
10-bore 700 grain ball
12-bore 593 grain ball
600 nitro express 900 grain
577 bpe 650 grain
500 bpe 440 grain

So far no difference in accuracy, velocity or pressure and NO lead in the barrel. Within a month or 6 weeks the snow will melt and I will recover the projectiles that will show no deformity (due to the soft snow they were shot into) and I will note the rifling grooves to see if the powder coating stayed on the bullet/ball or rubbed off during the trip down the bore. I will post pics when. But, so far all is well and I hope to retire both my RDBS lube-size machine (up to .50 caliber) and my pan lube tray for .577 to 4-bore.
Cheers,

Looking forward to your report Cal!
To you guys in Alaska, there may be a shortage of powder now that Cal is coating those big bullets!

I decided to take your chrono numbers and do some statistical analysis of them. In the tables below, you will find MEAN (average), ES (extreme spread) and SD (standard deviation) numbers for each of the 5-shot strings you fired. With your raw data, both the ES and SD favored the Powder Coated bullets, while the MEAN velocities were nearly identical (top table). The 1566 fps for shot #2 in the LUBED 375 Ruger load was far out of the norm, and heavily skewed the results in favor of the Powder Coated bullets. In the bottom table, I reduced shot #2 to an ES of 100 fps, and the results became almost identical. Unless the shot #2 high velocity was directly attributable to it being a lubed bullet (doubtful), then it must be related to either loading or chronograph discrepancies. I would say there is virtually no difference between lubed and powder coated bullets as far as the numbers go.



Did you notice any difference in the accuracy of the two different bullets? In my own testing of large bore revolver cartridges (44 mag and 45 Colt), I have found no difference in the accuracy of lubed gas-checked bullets versus powder coated. The powder coated bullets are, however, much cleaner and nicer to handle during reloading.

WHELENITE
no real difference in accuracy, the coated bullets do not lead the barrel ,,,the only issue I have with powder coating is I have no control on the thickness applied and working with really tight tolerances ..nose riding bullets some bullets which are powder coated cause issues with chambering and pushing the proj back into the case , and thus pushing the base of the bullets below the case neck, which has its issues again
I have started using HI TEK COATING and I think its just as good if not better far easier to apply once you know what your doing ....so im sticking to my HI TEK COATING
Also cast bullets coated with HI TEK coating do not stick together....PCbullets stick together and that's pain ful!!!!

In fact if memory serves me right I don't think there is much difference between powedr coated bullets and bullets coated with HI TEK coating as far as vel goes
