I did not steer anybody to small ejection pins quite the opposite , you miss read it .
Small ejection pins will cause ejection problems if they penertrate the meplat because ejection force is too high for the small area covered by the pin face. They can bend also. Good ejecting dies can get away with smaller pins but some are not so good especially after a bit of wear as die makers tend to leave a very small amount of wear available in the core seater. Some only .0002 . It does not take much wear to be a miss match with the point former.
I have seen a few long ogive dies that the polish on the die was not that good right up the narrow meplat end and they had very slight double ogives.
Of course good dies are good dies in any ogive but smaller ogives are easier to make and get perfect. Also shorter ogives produce nice smooth ogives with less wrinkles.
Joe, i never said that you steered anyone into small ejec. pins ,what i said was that i don't recomend to new bullet makers, perhaps you misread. small pins can pierce meplat and so can larger ones. you say good ejecting dies will work with smaller pins but some are not so good won't this is a die problem not the size of the ejection pin. also what you are saying is that the core seater wears faster than the point die ,no they wear the same.also bending ejection pins is a die design problem to soft of a pin or to thin a web to support the ejection pin. also the long ogives with what you call polish that was not as good at the narrow meplat this again is a die problem not ejec. pin size. a shorter ogive probably will give fewer wrinkles but lube,die finish and jacket hardness comes into play.i have made dies with ejection pins down to .040 on 6mm and they eject as good as .062 i make. as i said the small ejection pin causes other problems other than not ejecting the bullet from the die. i guess with what you have said the vld's that are being made won't work to good. george[/QUOTE]
I do not agree that the point former wears as quick as the core seater in general . In six sets of dies I have had in the past it was the cores seater that lost it's critical diameter first. After making a new core seater in every case the point former returned to good ejection and good bullets.
The core seater is prone to receiving more abuse than the point former which is part of the reason. However you don't want people to know that.
I never said a small ejection pin will not work. I said " Good ejecting dies can get away with smaller pins " That means well made dies work better with smaller pins than poorly made dies. That's a proven fact because I have had poorly made dies that developed bad ejection with a small pin and eventually broke a pin. I converted the point former to a larger pin and made a new core seater with a proper match and it now works good. That does not say anything about VLD not working.
Fact is George you are saying that small pins cause other problems but you will not part with any help in that regard.
You seem to think that only perfect dies exist and every die ever made is perfectly straight and functions perfect in every way.
That's just not the real world.
As I said before it is easier to make an accurate well made ogive if it's shorter rather than longer in general. If you have a professional shop it becomes more of a mute point. This thread did not start about PROFESSIONAL DIE MAKING. It started about amatures making their own bullets and stuff .
