Flash hole size

While cleaning a batch of mixed 45ACP brass, I noticed that the flash hole size was different between the different makes of brass. I always sort my brass, and load each lot by case manufacturer. But will this flash hole size difference, have any effect on my handloads?

None, it is from NON Toxic ammo load away!

For plinking/practice, no.

Some match shooters may argue that size of flash may affect powder burn rate.

I don't sort by flash hole size, even for my match loads. What I do is range test them (my qualifier being 2" group at 15 yards) - if reloads meet this, it's good enough for match shooting.

Flash hole size falls squarely in the "no problem" column.

Hope this helps.

Thanks guys. I figured it was a non issue, just never hurts to ask.
