Grrr. Broke a third one!!

Might be the 450 was designed to be used with lube and the powder coated boolits without lube are causing the problem with the in - out motion it uses .
I bet a straight push through sizer , like the NOE in post #22 , might work better .
I sometimes get resistance on the upstroke of the 450 , usually the sizing die is newer and they need some extra polishing to work smoothly...
might want to try polishing your sizing dies , wont hurt and might help .

I recently got a .359 Factory new sizer. First one I have bought in a decade!
I DID lube the first few bullets and THEY GOT STUCK!! Thinking back this could well have been the initial cause of this most recent failure. Probably quality has dipped from Lyman in that polish you speak of.

Its a lil better now that it has couple Thousand boolits thru it. But I STILL start with a lubed bullet AND lube every tenth or so.

I also built a die with the help of a member here and use lyman sizer dies in a push thru capacity. It works well as using them In single direction seems to be of tantamount importance.

Any how, In early this am and I chopped a couple Pieces of 1/4” stock.

Then halfed them and drilled holes.



Then ground them round on one end, chamfered other. On one I decided to try a angle. Maybe its better maybe no... Then I chopped a stick of Cold rolled 1/2” for the handles.



Lastly glue them together. I didnt make a jig as there is just two. So I held them and welded. Not perfect, But close enough! Couple degrees off will be just fine.



I left handles long as I only halfed what I had on hand.

Im sure Ill need to do a little smoothing and such. But here they is! Paint later. I dont wanna make any excuses for my guys to go home. Its already snowing like crazy, about now they start looking at me to say go home early... But after a short week last week we are behind! So we workin till EOD TODAY!

If one is seating gas checks or sizing PC'd bullets and "doesn't use them to lube" then one has no lube right? Could that be the source of the problem? Designed to drive a very lubricated mechanism? More than one post on it being "too cold" for the lube and that causing this problem, but OP indicates not using lube at all.

You might consider polishing out the inside of your sizing dies to lessen the force needed to push a boolit through them.
They may be rough from the factory or somehow roughed up during use.

Use some jewelers rouge and a cotton cloth wrapped
around a split piece of dowel or metal rod (be careful not to scratch anything).

comet/barkeepers-friend/auto-polishing compound may also work in a pinch.

I have been using #1's and 45's for over 50 years and have yet to break anything on one , maybe i'm just very lucky .

Well they fit but I needed to do alot of grinding. Both would be fine for GC, but only One works 80% overall.

I remade the other one.



Im sure Ill beed a bit of tweaking. But this should be closer.
