Question for the painters among us. Does powder coating negate the need for gas checks in revolver rounds? I know that a properly alloyed/lubed/sized plain based cast bullet can be run to ≈1200fps and that guys routinely run plain base painted bullets higher without issue, but how much higher?
I'm looking to get a new mold for the 357mag and would love not having to fiddle with gas checks.

Yes you can do this without problems if you use a Flat based Bullet. NOT A BEVEL BASED BULLET. Of course this depends upon the size of bullet and it helps knowing the mix (alloy/lead)
What do you want to do with these bullets? Paper, Steel, Hunt, or competition?

Thanks, CT. I'm not really a bevel-base kinda guy, so that's not really an issue. Planning on using them for hunting. I figure with a little tinkering I can get the alloy right (my stash is range scrap, lino, tin, plus a bit of WW).

odin, CT is correct, powder coating will help you shoot a plain base (flat) bullet faster without a gas check by a fair amount. There is a point where you do have to go to a gas check, think 357 Maximum if you want to get top end velocities plus not all 357 magnums are created equal, some will lead at lower speeds than others. Once in a while some guns can lead quite easily unless you fire lap. Check out Fermin's excellent thread on fire lapping if you have one of those guns, he'll walk you through it. I'm guessing David Bradshaw can help out here on barrels, he was born with one in each hand.

Some barrels are far smoother than others. There is no hard and fast rule!! Send me a PM with your contact information. I’ll give you a call and do some splainin’. |

Not much to add to the counsel of Sixshot and 2 Dogs. At all hazards, cast bullets must be tested in their intended guns. Commercial jacketed bullets----I’m talking about Sierra, Hornady, Speer, Nosler, and other top shelf jacketed----run amazing uniformity. Providing a correctly made (and sized) cast bullet, ACCURACY and LEADING come down to CHAMBER (dimension & finish, CHAMBER to BORE ALIGNMENT, FORCING CONE (dimension & finish), BORE (dimension & finish), and GROOVE (diameter and finish). Bore and groove must be uniform. All the smoothness in the world cannot save a wavy bore with tight or loose spots, or a bore with tight and loose spots. Remember, the Old Timer would SLUG his or her bore as a routine act of handloading preparation. A couple of generations seem to have forgotten this critical step.
And then there is the CROWN. The cleanest, squarest crown cannot restore accuracy ruined between chamber and muzzle.
In the growling words of Sixshot and Fermin, a revolver is an individual. I have tried to illuminate a bit of what they’re talking about. If the target out yonder whispers, “GAS CHECK,” listen.

What on earth would you guys think Dick knows about Gas Checks? The last time he probably used one was way back when they were still making them out of left over Carthaginian battle shields. And even then his loads couldn't keep up with a Roman 3 decked war galley unless one side of rowers or the other called in sick.
The other thing I can't figure out is why people keep asking Dick about powder coating? Don't any of you realize he is referring to baby powder and what he is coating is...well, let's just cut that thought right here....

Next the Dawg will be saying my loads are so slow I can use the same gas check 3 times!

Next the Dawg will be saying my loads are so slow I can use the same gas check 3 times! Dick ***** Dick.... may have to reload the same bullet between pig and ram. Now, if you can make the gas check fall off between muzzle and chronograph, you may be able to reuse the little coppers... As for me, I’m still trekking snowshoes to shoot 100 yards, and this season have yet to collect a fired slug in the snow out to 400 yards. Good shooting, David Bradshaw |

David, like some of the old Lyman stick on gas checks that would abort the mission upon barrel exit! Also many on here may not remember that RCBS made gas checks at one time, I still have some! I cuss gas checks from time to time just to keep Fermin barking but they can cure many ailments when a six gun isn't shooting it's best, no doubt about it...... dang it, I hate saying that!
