better to have a gun and not need than need it and not have it
nothing to worry about
It would be unusual if you didn't get a line...not joking.

A small seam is normal. Flashing isn't.
Keep the mould closed firmly, even tapping a new tight mould when closing it can help.
It's possible that you have a speck of lead on the inside face of one of the mold blocks if this is new. Such a speck will be barely visible but will hold the mold halfs open just enough to make a slightly bigger boolit and create such a seam.

There is no 'right' that requires me to work for you or you to work for me!
Thanks guys.I have noticed some "flashing" I think.That's when the lead seeps out do to the molds not closed tight???I just re-cast those.If I get a very minute amount of flashing(on the nose)is that okay to size and use?

check the mold halves
may have a smear of lead on one or both
the parting lines are no biggie like the others have said
Hit em'hard
hit em'often
Sometimes squeezing too hard on the handles can cause large seams or flashing.
Peened mold metal, warped molds, proud or crooked alignment pins, and as white eagle said, the tiniest flake of lead on the mold face can do it, too.
I give loading advice based on my actual results in factory rifles with standard chambers, twist rates and basic accurizing.
My goals for using cast boolits are lots of good, cheap, and reasonably accurate shooting, while avoiding overly tedious loading processes.
The BHN Deformation Formula, and why I don't use it.
How to find and fix sizing die eccentricity problems.
Do you trust your casting thermometer?
A few musings.
When I got my very first mold I did the whole prep thing with everything I could find on doing so. Not knowing any better I went a little overboard on my taking a sharp knife to the edges of the cavitys and now my boolits have a stripe or seam mark around them.
I didn't think I took much off but it was enough to leave a seam mark, I shoot these as cast and they do fine.
Thanks guy's.
