As I was weighing 340 gr cast bullets I considered the parameters I was using which is .5 gr . I couldn't remember where I came up with this so I went back through the literature that I have and found that in the RCBS manual .

This seems a little questionable as I think that it would be a percentage of the weight versus a set value .

So , my question is , how does everyone else segregate/cull their cast ?
This is for my .454 by the way ......

Thanks in advance !

For most of my loads it just does not matter. + or - 5 grains (that's 5 not 0.5gr) just does not make an issue at 25 or even 50 yards. I'll weigh a percentage of any new cast bullets I buy (new weight or new style) just to see how consistent they run but other than that I've found no noticeable difference in performance.


Long range rifle bullets would be a different matter. However few long range shooters use cast rifle bullets.

Unless you're shooting in precision bullseye competition, there are just too many other factors more important to worry about than a few grains variation in bullet weight.

Same thing for powder charges. Unless you're right up there against the maximum, a few tenths of a grain either way isn't worth worrying about.

Even in Bullseye competition, weight variations of UP to 3 grains will still go into a group of under 2" at 50 yards.

I'm pretty anal about my 50 yard cast bullets and have done a lot of Ransom testing.

Subject to the pistol's accuracy potential, the quality of the load, one's ability to use a Ransom rest, they're usually good to go as long as the bases are perfect & there's no visual flaws . This would also require your casting technique and lead mix to be consistent.

At 25 yards, you can pretty much load anything & they'll stay in the 10 ring with most in the X.

when I'm casting I reject the bullets that the bases don't look perfect (square) in the mold and then use gas checks .

So maybe I'm thinking too hard , time to quit weighing and start shooting .
thanks for the response !!
