I have a 358429 two hold mould that is just about big enough. My .3585 push through sizing just touches the edges of the bullets...most of the time. The mould is hot before I start, I keep a thermometer in the lead pot while casting, I try to leave the same size puddle on top of the cutter each time yet when they are cool some get polished pretty good going through the sizer some just push through with no resistance. If they mic .358 I go ahead and use them. I'm doing something to cause this and don't know what.
What am I doing?

I'd go with handle pressure too.
easiest way to tell is by measuring the direction your sizing.
wide across the seams variance is most certainly mold temp.
across the mold is generally handle pressure or the pins ain't lining up quite right from one to the next.
personally I'd lap the mold when it was hot, size them all down to the same and not worry about it so much.

Though I think I'm applying the same handle pressure, with each cast, there have been times when I notice bullets with fat seams. Too, there have been times when the handle pressure was so light that bullets had fins.
I put it down to getting caught up in the casting rhythm and not concentrating on all the particulars.

I think Lyman's poetic potential comes into full effect on the #358429 mould offerings. They are truly like Duesenberg automoblies--"No two are alike".
Shake my head--my eyes must be stuck. I found the locking mould handles on the ST Machining site, but the sprue plates are hiding out. I could use about a half-dozen of those critters.

What am I missing here...
The problem is bullet size??
Different alloys will size differently. USUALLY a softer is fatter.
I have two 358429 molds a 2cav and a Single cav HP. The 2 cav is as you describe. Drops smaller than I like. But the HP is fat and drops closer to .360.
But I powder coat. So size is seldome a issue unless its bore rider diameter. Now I complain of too fat a bullet!!

Nah, I just wanted Rick to have them. I haven't looked elsewhere yet.
Tomme, my lead is whatever melts. The weight is right on 173 grain so it is close to OK. I suspect the mould is cut a bit small like Lymans are and the grip pressure does make a bit of a difference. I'll try to increase size when I can get to town and pick
up some lapping compound. I don't have enough to do anyway. Yes, it groups OK when I can hold steady but at my age it is starting to take two hands to steady a coffee cup!

If some of the bullets have fins on it make sure nothing is in the hinge or else where.It will make that and the bullets larger, it dose not take much alloy to make your bullets come out different. also like Rex stated do not worry about the bullet as long it groups ok for you. For handgun you have more to play with then rifle. Just remember your alloy mix or use for that bullet. This is what I found for me, it is rifle shooting is when things show the much.
