Acceptable Weight Variability?

[pcw907]

I am casting with the brass .360 WFN from the group buy here last year. Out of 350 bullets cast this week, all but 20 are between 178.0gr and 180.9gr. The rest are as light as 175 or as heavy as 185.

My question is "Is a +/- 1.5 grains from 179.5 grains acceptable variablity for this bullet?"

Thanks

yes.
the light ones are most likely from the start up.
i don't weigh revolver type boolits.
i toss back the shiney ones and bad bases and anything i just don't like the looks of.

What RFR said, I don't weigh pistol boolits eather just look for good fill out and good bases.
Rifle boolits are another story.

These are for a carbine in 357 mag. I stated in another post I was getting sub MOA with jacketed, but not cast. Just trying to tighten up my QA to tighten up my groups.

EDIT: Actually, 2 carbines, and 3 revolvers.

I only weigh my handgun hunting or rifle bullets. Anything much lighter than the avg probably has an internal void & gets tossed back. I am good to go w/ 2-3gr variation in larger bullets.

I would re melt the lighter ones and try the others.
You never really know till you shoot some to find out.

Check the diameters of the light and heavy boolits. I think you what you find will be interesting.

+ or - 1% for me. Electronic scale makes weighing them quick and easy.

Great advice everyone. Thanks. I have a 25 loaded for this weekend. Cases trimmed 1.280-1.283, powder measured to within 0.5 grains. I will let post how it goes.

[runfiverun]

your q/a q/c will be fine.
it might be a weight /twist rate compatability issue.
or a barell diameter thing.

for some odd reason some barell makers think we only want to shoot 125gr bullets in our 357's or 200 gr boolits in our 44's,or 220 gr bullets in our 308's.

I don't get excited about weight variance in handgun fodder. As long as they pass visual I load and shoot them. That said, for rifle, the smaller the blt, the more critical. For 22's I want exact weights, for heavy 45's, 1-2gr. don't make a lot of difference in my experiance.

When I first started casting I weighed all my boolits. One day I realized I was spending more time casting, weighing and worrying about variances than loading and shooting. For the last 35 years or so I haven't weigh handgun boolits at all. Those few at start up that look questionable go back into the pot. The rest get lubed, sized and loaded. Given the handgun distances at which my wife and I shoot, not weighing has turned out to be a good thing.

But, I am pretty anal about clean alloy and casting consistency and no doubt that helps in making weighing unnecessary.

For pistols if it sort of looks like the boolit that the mould is supposed to throw I load and shoot them. My pistolero skills and shooting needs just do not justify the time it would take to weigh my boolits for pistols.
