I "thought" I was going to pass on the used 650 and get a 550 kit...
Looking at Dardas cast bullet site
There are two important elements that need to be considered to produce trouble free cast bullet reloads. The first element is case mouth preparation. I always recommend that the Lyman 2 Step M Die be used to prepare case mouths properly. This die will allow the cast bullet to be placed into the mouth without tipping. The second element is the seating stem. Make sure that your seating stem is contacting the bullet's ogive about mid way down from the tip of the bullet. And make sure that the tip of the bullet is not contacting the seating stem where the hole opening is. The clearance hole MUST be large enough to allow the bullet's tip to clear. I strongly recommend that you use Lyman dies for cast bullet reloading.
Please do not use a Factory Crimp Die for cast bullet reloading. Cast bullets MUST be seated perfectly square to provide trouble free accurate reloads! Cast bullets MUST remain in their pristine state in order to shoot accurately. Factory Crimp Dies will alter the cast bullet's sized diameter and thus will cause many unwanted issues.
Are the Dillon dies really that bad to load unplated bullets? The owner of Dardas, Matt told me that $100 off the price of a used (well used...) was a fantastic deal and I should jump on it.
I am still so confused, LOL
