My .30 Reloads ran great today

I will bet that you were the ONLY one in the contest shooting a 30 Luger chambered Luger.

Yeah, you bet right. I've never seen another .30 at that range or any other, and hardly any Lugers shooting at all ever.

I should also mention that the gun shoots maybe 6" high at 50 yards, I ended up aiming at the bottom of the 8-ring when I figured out where it was shooting. It was much closer to POA at 25 yards, of course.

My chart shows it to be fast-burning, and 4.1grs a fairly 'light' load...Maybe 1000-1100fps???

That sounds reasonable, I would have put it at near-supersonic speeds from the way it sounded, but haven't chronographed it. That same load of AA#2 under a 115 gr. plated round nose is also pretty light (for a 9mm) but it runs my Ruger P95 and Hi-Point 995 TS (rifle) just fine as well as my 9mm Lugers.

What dies are you using?

Taper crimp or roll crimp???

RCBS dies (2-piece). I don't mind the combo primer removal and expansion dies, but I wish I had separate seating and crimping dies as the adjustment of both operations simultaneously is tricky. I ruined a few pieces of brass getting it right.

I believe that a taper crimp is applied with these dies.

I also have the RCBS 25001 die set, but I use a 22-250 decapping pin/punch in a 44 Magnum sizer die to punch out the primers before tumbling (and before sizing). I just got into the habit long ago. It probably has no benefit. It doesn't do anything to the case itself. I've convinced myself that it cleans out the primer pocket before the other operations. I do the same for pretty much all my reloading.

Someone here mentioned a Lee roll crimping die for seating/crimping the bullet. If anyone knows the Lee part number, I'd like to try it. None of my .308" bullets have a cannelure, but it's something to try.

I had one of those collet-crimping dies once, like a R8 collet, and it was pretty much worthless. I forget what I was crimping/reloading, but I like the basic idea.

...???...Just curious: How do you roll crimp when there is no cannelure???

It's possible that RCBS has changed die forms over the years...I know there are at least three different RCBS die set numbers for the 8mm Nambu; possible for the 7.65 Parabellum as well...

The problem I had with the R8-style collet crimping die was that I could not get enough leverage on the collet/press to compress the collet. It worked by drawing the collet down in the die and the lip was supposed to compress the case mouth...It didn't...The bench would lift off the floor first...
