sorting .32 bullets

Do you sort your .32S&W wadcutter by weight? If so, with what tolerance?

I was using Lapua and Speer 98gr bullets so far and they were quite consistent. I weighted about 200 Speer bullets from my last batch and the weight tolerance was +/- 0.3gr which I decided to be insignificant enough so I didn't sort my bullets till now (I had other issues with these bullets though).

Yesterday I got my first package of H&N .314 100gr greased HBWC bullets. I was pinning my hopes on them and they looked really nice and shiny at first glance. But when I weighted only 30 of them it turned out that they weren't particularly consistent in their weight - the extreme spread was almost 5gr!
I still didn't try them out but I have a feeling that 97gr bullet can hit a target in a different place than a 102gr bullet (or maybe not?). Then the question is: are your bullets so inconsistent as well? How do you handle this - sort them or just ignore it?

Greetings,

With the commercial swaged bullets, I do not weigh them. Think about it. The bullets have grease or lube which is probably inconsistent. So are you determining the uniform weight of the bullet or the grease?

When I swage my own HBWC bullets, I have weighed them. They would vary +/- 0.2 grains. Currently, I just "squash" them and lube them with the Lee Liquid Alox. If I were to start shooting well again, I might consider weighing them.

I think that uniform shape is more important than weight. By shape, I mean no nicks or dings and "hopefully" statically balanced.

I have attached images of the home swaged bullets tested at 50 yards using my Haemmerli SP-20 barrel.

Image 0001.jpeg is the H&N 0.314 100 grain HBWC for comparison.

I have recorded the best groups in my barrels with the H&N bullets.

With kind regards,

David

Dear Dave,
You are absolutely right, grease (or lube) is definitely an important and probably inconsistent factor in a bullet's weight. I just simple expected a smaller spread. For example, Speer bullets that I have tested varied only +/- 0,3 grains. So I was really surprised to see such a significant weight spread in H&N bullets. However, both manufacturers use different kinds of lubes for their bullets.

I must admit that most of the H&N bullets look almost flawless. I can't say the same thing about Speer bullets.

I'll prepare a testing batch and then I will know for sure. Thank you Dave again for your invaluable input.
