OK loaded some rounds up and these are the results as best I can determine.
On my Dillon XL650 I found that I could definitively feel each primer being seated in the .223 case whereas while loading 9mm (commercial brass) I found it hard to feel the primer being seated at all. That being said I must point out that I am brand new to reloading and have only reloaded a couple of hundred rounds in both 9mm and .223 calibers. I did crush one primer (.223) but could not determine the reason as it was not discovered until after the reloading process and I was examining rounds. However, from my examination of this round it does not appear as if the crimp was removed or that it even went through the process of removal.
Here is my reloading data . . .
Brass: Winchester (Military)
Bullet: Wideners Mil-Spec .223 75gr HPBT
Primer: Wolf SR
Powder 23-25 gr Hodgdon H335
Results, five recovered empty cases had a primer missing; one jammed the rifle ending the day; one misfire showing a light firing pin strike. Two of the missing primers clearly came from rounds that had the deeper cut from before I fiddled with the tool/bit and somehow, after reassembly, ended up with a shallower cut despite all attempts to return it to the original cutting depth. The other three are hard to tell. None of the other rounds, with primers intact, had evidence that the primer was moved either into the case due to primer strike or outwards from recoil, in other words all primers seemed to be still seated to the correct depth.
Conclusion: I think I will save my money up and get the Dillon Super Swage as there seems to be little documentation, instructions or otherwise on the RCBS tool with which to determine whether I am using it correctly. RCBS says to just push the brass down until it stops cutting and that if it appears that the cut is too deep, well that’s just an optical illusion.
Tool grade: C if I knew more about reloading I would probably be more confident in the use of this tool and more likely to use it correctly. Not for novices in my opinion.
