Falloutboy89 Posted July 15, 2019 Share Posted July 15, 2019 (edited) How can I prevent this? Everything I have loaded to date has been 115 or 124 FMJ RN. I have seen a somewhat slight taper in on the mid-section of my fully loaded rounds. Never saw this before - I loaded about 30 as a test to Chrono. I shot about half and the fps seemed fine. Hell, they were accurate too. I also performed the plunk test (on some) and used a case gauge on every round. 9mm 3.3 gr. Titegroup FC Brass 1.070 OAL 147 gr.

BJB Posted July 15, 2019 Share Posted July 15, 2019 That is from use of an under-sizing die and then the fact that a longer 147 gr often has to be seated deeper into the case getting down to where the brass of the case starts to thicken, which is about .3" or so I think. It's all a-ok. Link to comment Share on other sites More sharing options...
Falloutboy89 Posted July 15, 2019 Author Share Posted July 15, 2019 Thank you both. I'm not a fan of the look that's for sure. I love this forum. Read the thread MM shared which lead me to one from 2017 which then lead me to one from 2014. All filled with useful info. Thanks again! Link to comment Share on other sites More sharing options...
BJB Posted July 15, 2019 Share Posted July 15, 2019 Ignore the "look". It doesn't matter. The under-sizing of the brass does a great job of preventing bullet setback. Taper crimping doesn't hold the bullet, just removes the bell. Link to comment Share on other sites More sharing options...

Blackstone45 Posted July 15, 2019 Share Posted July 15, 2019 I also had a similar concern about a slight bulge in my loaded rounds. My friend told me it's because the dies are sized for the lowest common denominator, which is the thinnest brass expected. Reloading is something we should rightly be overcautious about as newbies Link to comment Share on other sites More sharing options...

Are you not a fan of TG? I've read comments about ppl suggesting its easy to double charge. I have the powder check installed on my 650 too. Please clarify if you don't mind...

ltdmstr Posted July 16, 2019 Share Posted July 16, 2019 As stated, it's the interference fit that holds the bullet and prevents setback, not the crimp. And a bit of a muffin top is normal. But that looks excessive. What sizing die are you using? Link to comment Share on other sites More sharing options...

4n2t0 Posted July 16, 2019 Share Posted July 16, 2019 Mine look exactly the same with a 147gr bullet which I load with 3.6gr of Titegroup. Keep them coming... Link to comment Share on other sites More sharing options...

I've read comments about ppl suggesting its easy to double charge A double charge of anything is a Very Bad Idea. But, no, I'm just joking - seems to me that 3.3 TG is a Very Light load and constitutes so little danger (except for a dbl charge). Guess I should stop kidding around.

noylj Posted July 17, 2019 Share Posted July 17, 2019 TG produces pressure spikes at low loadings. TG also does not handle even minor over-loads very well. TG is a fine powder, if it works for you. Personally, I would get a standard Lee sizing die. Standard Lee and Hornady sizing dies go down almost as far as any sizing die can. Dillon is very sloppy and the rest fall in between. If your round feeds and chambers, ignore the bulge. If it goes all around the case to the same extent, then it is a result of the undersized sizing die and an expander plug that doesn't go down far enough. If it is only on one side of the case, it is the result of seating the bullet crooked (where a better expander plug, more case mouth flare, and a better fitting seating stem might be good investments). Always, always inspect the powder charge in the case before placing a bullet on top. Use your eye or an RCBS Lock-Out die, no matter the cartridge or powder being used.

I learned this the hard way - loaded 200+ rounds and Some of them have powder and some don't (that's after 40 years of reloading without Ever having had this problem).

Mechanical parts can break, go out of spec, etc., and you might not know it. You will know pretty quickly if your eye breaks or goes out of spec.
