No plans to hot rod them...just starting out.

What mag pistol powders do you have.... I know you run 357.No plans to hot rod them...just starting out.
Lol
Well your not going to put Bullseye in a 6mmI have several. But,I lack bullseye
Use the 85 grain bullet load and 4227 and test away.... I actually like 2400 in the 6.5x55 but one should start in the data firstUnique,red dot.4227.2400,blue dot.trail boss.etc
And it still might be your shortest lived barrel! I do think handloading can mitigate the throat erosion by generally using moderate loads, but I don't know how bullet weight or material affects wear. Maybe leading protects the throat lolNo plans to hot rod them...just starting out.

If you use a small powder load of a fast burning powder and a lead bullet, it won't last forever but nothing else will last longer. 40 grain loads to 18 isn't compatible for heatAnd it still might be your shortest lived barrel!

I think shooting .243 is what will compel me to start doing barrel work on my lathe but I haven't ruined one yet.
I’m down to two pounds of IMR 4198 plus a few drams in an old bottle. I wish I had bunches of it. IMR 4227 and Hercules 2400 are both made with this type of application in mind but you might have to reach for tested loads. I’m thinking magazines or pet loads articles. The .243Win is a cartridge from the jacketed bullets era. I think trying to force H4350 to fit a use-case with no data is a bad idea but I tend to be pretty conservative.The don't even use powders as slow as 4895. I have bunches of 4198 for cast so no doubt that's first choice.
I posted the 243 picture from my cast manual, it had all the data the op would need. When I say a bunch that's shortage scale of 4.5 pounds. I've loaded my first half pound between 308 and 30-30 and not pulled the trigger yet. I could now probably be on the schedule of a lot of these guys where I can shoot all year with what's loaded.I’m down to two pounds of IMR 4198 plus a few drams in an old bottle.

UCertainly No offense meant but I'd like to ask ; WHY use cast bullets in Rifles period ,when jacketed are just not that expensive ?.
I understand people cast their own ,but generally either older slower cartridges or pistol loads ,which again are slower .
Now I use cast bullets with and without gas checks in MY .44 mag. as well as .45 Acp . However I don't have slower Rifle calibers ,so NO cast bullets .
I know I visit there once ina while.. thankssavagelover, I’d go over to “castboolits.com” to seek answers. I’m not knocking anyone’s opinion here, but those guys live and breathe shooting cast.
70s-90s is the cast boolit zone. Pick one and party till you hit pay dirt or the pound is gone and mulligan.View attachment 1126000 If reloaders did not experiment with powders we would all be shooting the same loads, pick a powder in the appropriate burn rate and start low with a charge ladder to qualify or eliminate that powder. If your firearm doesn’t like the combination you’ll see it quickly on the target.
And the prize for mixing metaphors goes to…70s-90s is the cast boolit zone. Pick one and party till you hit pay dirt or the pound is gone and mulligan.

Interesting. Thanks hope to cast up some this week if it warms up someThe 243 is not the most popular gun for cast bullets.
I am not sure how much help you are going to get with actual experience or published load data. Of the powders you listed, Red Dot is one of the most common fast powders used for reduced power rifle loads.
Here is some Quickload info. I chose one bullet diameter for seating depth to keep the gas check in the neck. I chose several different calculated chamber pressures and ran your powders that I would be willing to try if it were my gun.

The .243 is capable of very good cast bullet performance.
The key phrase is “cast bullet performance”
Keep chamber pressures below 45,000psi and velocity below 2,300fps and you can see good accuracy.
Performance on game will be good for up to 175lb deer.
I’d start with #2400. It’s given me great performance over a wide range of cartridges.
H4895 is another good one, but don’t try to get jacketed velocities. You’ll just load your barrel with lead fouling.
You’ll not like 4350. At lower velocities/charge weights you can get hang fires and flash-overs.
Size cast bullets .001-.003” over bore diameter. I suggest.244” a minimum for .243.
I use .311” in ALL my .30cal rifles.
.314” in .303 (.303 Brit, 7.62x54R, 7.62x39.
I use SPG after tumble lubing for peak rifle accuracy.
Added: My two Marlin.45/70’s are among my best cast bullet rifles.
I use .460” sizing. One has Microgroove rifling, other has Ballard style.
Ballard style Remlin (circa 2015-6 mfg.) does this over 20.0gr #2400 with Lee 400gr RFN. About 1,400fps.

Yeah, I use the 4350 (I or H) for 30-06. With around 2850fps with mid level charges.Maybe, as I have noticed with H4350 is fairly low density. You may not be able to fit enough H4350 in the case to make it go fast enough.
For example I can't fit enough H4350 in new 8x57js brass to hit my rifles accuracy node or even fit enough H4350 to get to the max book loads.
