How big is too big?

[Lost Sheep]

I know lead bullets should not be undersized for the bore or you will have leading problems, but how much over can they be?

I ran across grizzlycartridge.com wherein they sell a 50 caliber bullet .511" in diameter. For a 500 S&W, this seems a little excessive

yes that is much to big. What you are looking at is for a different fifty cal gun such as the 500 linebaugh,.50 Alaskan, .500 Jeffery ect.....

The thing is the finished round will have to FIT IN the chamber. A bullet that will expandthe neck over the size to do that is wrong. Most sources state that a LEAD bullet .001-.002 larger than groove diameter is what is needed to seal the gasses in without leading. I would consider this to be max size in most cases. You should get a micrometer and be using it if you do not already have one. This tool will tell you a lot about the size of the necks of your reloads.

That is for .50 cal Black Powder not the .500 S&W.
This place has a .501 S&W 325 gr TC bullet that I have bought that works very well. www.pennbullets.com Very good stuff and great service.

Wow! Those are some prices! That means the 440 grain 500's I just cast are worth $54.00! Holy cow, I'm rich! Actually he's sizing them to .500. Not good! They should be at LEAST .501. Although I haven't actually slugged the bore of the 500 smith I'm loading for, the .501 boolits I'm casting work real well. Since Lyman and RCBS don't make a .502 sizer die, I'm stuck with the .501 boolits.

Lead bullets need to be as big as the cylinder throats are. Lead will swage down without any issues. So do jacketed bullets with soft lead cores for that matter. That is whu slugging your bore and chambers is important.

I go as large as the chamber/throat/leade will accept easily and fully seat, allowing the barrel to be the best bullet sizer made during firing. For example, .359" is no problem for my Beretta M9, and it pays to experiment not just with diameter, but lube type, alloy, etc, OALs...

Yep.

What lost sheep was asking is about the grizzly bullets he found. Those bullets are for the 50 BMG, not the .500 S&W. The link I provided is for the .500. There's just not much available for the big 500. This guy insists on sizing his bullets at .500. Lead should be AT LEAST .001 over bore diameter, his are right on!?

The boolits I make for the 500 I load for drop from the mold @ about .503. I use a Lyman .501 sizer in the 450 lubrisizer, because there are no bigger ones available. (Except for .511.) I haven't slugged the bore or the cylinder throats, but it doesn't lead-----MUCH. A few traces that come out with a bronze brush.
