I just received a replacement 9mm sizing die from Dillon for my Square Deal B. The inside diameter is .373", compared to .378" for the old sizing die that was giving me trouble. All brass (Speer included) now sizes properly and the Glock fired brass chambers easily after sizing. Problem solved - thanks to Gary Kieft at Dillon for the quick service and to Guy Neill for making me think of this as a possible solution. Good shooting, Allan

I just compared them yesterday, actually. The RCBS is .372" ID while the Dillon is .378". I don't see how the Dillon die could EVER size 9mm small enough. When I measured the wall thickness of a variety of cases, I found them to average .010" thick. If you take .378" - .010" - .010", it comes out to .358", which is bigger than the diameter of the 9mm bullet by a couple thousandths - no wonder the neck tension is inadequate with the Dillon die. Thanks for making me think about this Guy. I'll call or write Dillon and see what they say. You are made me realize this probably isn't a Glock brass problem at all, but a die problem. Allan

In case anyone else has this same problem, here's what I've done to 'solve' it. Run all brass through my cut-down sizing die on Rock Chucker, then run it as normal through Square Deal B. I found that the Winchester and Remington brass isn't sizing down enough either; the Speer and Federal cases are thinner and therefore the problem was more apparent, but the Win and Rem cases don't have enough neck tension on the bullet either, so I've opted to resize everything on the single stage prior to loading. This makes me think I might have to sell the SDB and go with a 550 or 650 so I can use a standard die - the lack of adjustability on the SDB sizing die is disappointing. FYI Allan

I'm resurrecting this because I'm having the same problem as DrKyle1, only I'm using a newly purchased (bought used) Square Deal B. I have been handloading 9mm on a Rock Chucker for years. I had to trim the bottom of the RCBS carbide sizing die down to fully resize the 9mm case after firing in Glocks due to their oversized chambers. I recently purchased a 9mm SDB and after setting it up and carefully gauging everything, I sat down to load 100 test rounds. I used a Remington 124gr JHP, CCI primers, and mixed brass. After completing the 100, I found that the rounds loaded in Winchester, PMC, and Remington brass were exactly what I wanted, but the ones in Speer and FC brass wouldn't hold the bullet properly - I could push the bullet in (or pull it out) of the case with just my fingers. I did some measuring and found that the SDB sizing die wasn't sizing the brass small enough to get good neck tension on the bullet. I resized some of the Speer brass in my Rock Chucker and it was fine. Has anyone had a similar problem with Speer or FC brass in a SDB? If so, were you able to resolve it? I have the SDB sizing die adjusted all the way down and I don't see that I could trim the bottom of it like I did the RCBS die. I know I can just cull out the Speer and FC brass, but I'd like to be able to use it in the SDB if possible. Thanks for any suggestions, Allan Davis
