I'll be shooting these rounds in a marlin lever action carbine......I thought I would start out at around 1200fps.
Let me know what you guys are doing with this round.
TNX in advance.

Several threads here about PC and velocity...
My Anchor is holding fast!
Light Speed of course.
Of course

Still goes by boolit weight and pressures. You can shoot a PB uncoated boolit to max with a good lube. Powder coating does not let you go over.
I think you'd be looking at the same velocities as with conventional lube, which depending on what powder you use and barrel length could be in the 1700-1800 fps range on the high end.
Prob as fast as data will let you get away with. I've shot 308 at around 2200 fps much higher pressure round and semi auto to boot I'm thinking top data
Tnx for the input guys...
I'm with 44man. I load and shoot PB boolits of ACWW or range scrap right to max velocity in my Marlin and no leading issues. I wouldn't bother with PC for that use unless you are getting leading fro some reason (like tight spots in the bore which I had but removed).
PC'ing certainly wouldn't hurt, I just don't think it is necessary for this application.
YMMV
Longbow
PC doesn't have an established upper velocity limit. It does, however have the same accuracy limitations at high velocities as uncoated lead. So you can very likely break 3000fps without leading with a good powder coat, but you will likely have abysmal accuracy. Likewise, peak accuracy is still alloy dependent with coated bullets although you can sometimes shoot much softer lead without lead deposits.
In short, powder coating fixes most leading problems, but accuracy still requires most of the same rules as traditional lead bullets.
Generally if you are using powder coated bullets and you do get lead deposits in your barrel it is because the coating is being broken through firing somehow. If your barrel has a sharp lead to the throat is what I have seen as the common culprit. Another suspect would be shaving lead during seating.
Keep in mind that powder coat is a somewhat experimental field so some of this information may become obsolete with further experimentation.
"(T)he fastest you can push a .44 magnum .430,240grn with powder coating"
Going with a good coating that has not been compromised during the loading, both case and weapon, process, the correct answer is as fast as any other bullet of the same weight with the given powder. In my opinion, as fast as any jacketed bullet of the same weight. Yes, their is some change due to the hardness of the bullet in the barrel but minor adjustment to compensate for the change in pressures, the same or nearly the same velocities should be achievable.
However:
With no velocity limit set (do to leading or other physical break down of the bullet), the length of the bullet in relationship to the barrel's twist may well come into play for proper stabilization. Velocity is one of the prime factors in stabilization and exceeding the velocity point that proper stabilization can be maintained is very possible. So, the question of 'the fastest you can push' becomes more of a question of is this with accuracy or just speed only?
I commonly push little 130 grain, 30 caliber cast lead with powder coating to well over 2800 FPS (2877.4 FPS measured at 10 feet) from a 22 inch .308/7.62 and have had no stability problems. The rifle does have a 1 in 11 twist. How accurate are these loads? Fine for me but I have macular degeneration and 'pin-point' accuracy is a problem for me. 20:20 with white fog in the way.
The final answer is 'fast'.
Enjoy,

I can run plain based, conventional lubed to 1400fps w/o issue, not even hard cast. I would think the coating would hold up to any vel you can get in a 44mag.

I am relatively new to all this and by no means an expert. Heres my 44 experience:
I cast and powder coat relatively soft scrap range lead at various weight for the 44mag: 143, 165, 240gc, and 310gc. For the 143swc and 165rn I am using those inside and never push them over 900 ft./s. The 240 grain gas check I load hot with H110 up to 25 grains. No tumbling and decent grouping at 125yds (shooter limitation, red dot not good to 125,etc, mainly the shooter). For the 310 grain I use 21gr H110. They are monsters. I am on my lunch break and dont have my load data in front of me but I believe I ran those thru the chronograph at upwards to 1400 ft./s. No real reason to make or use those as I only hunt deer but they are just a ton of fun to shoot at concrete blocks etc. I received this load data from a Hodgdon tech when I called for Powder help. He says he casts and shoots this same load with lubed 310 grain for very successful hog hunting. It should be noted that we are using Ruger SRH 7 1/2. Disclaimer: I have also talked to Ruger tech and they do not advise using a 310 grain bullet. Too much pressure. His warning was was something along the lines of we have blown the tops off SRH with these loads on the test line. Why the hell would you want to make a Casull out of a 44 mag? Are you an idiot? That being said the original point was powder coating works well and I never have any trace of anything in the barrel after a shooting all afternoon.
143 is an Accurate Mold 43-143M (my design)
165 also Accurate Mold 43-165CM (also my design, never made it into catalogue 😕
210gc and 310gc Lee 6 cavity
I shoot the max load in a SW 69 revolver and a Ruger carbine with no problems. I mostly load 700X and PC.
I enjoy reading older topics, so I also enjoy it when folks post in them to add a fresh outlook on things.
While I am not into pushing my 44mag up to or past Max velocities, I still enjoy reading about the doins of those that do.
BTW, I would also like to remind some though, that one should not expect replies from "some" of the ones who posted earlier, as "time" has a way of interfering with some folks being able to do so, and some are not around to post replies.

JB Mn- I was looking up powder coat data to see what other folks were doing for max velocity and ran across this old thread. Thought I’d throw some of my new data about it in case anyone was thinking about doin the same thing I am. I’m havin really great luck with powder coating for the indoor and outdoor ranges. Thought I’d pass along. Same as you, I read the older posts, very helpful to me
As a ''GOLDILOX CLUB'' member I stay @ 1000fps. Not too fast. Not too slow. Jess Rite
leave the 44 mag for a handgun and step up to a 444marlin for a carbine
