Ok guys, new member here and new to reloading... really new.
I got me a press, some brass, some dies, bullets and all the fun stuff. Read a couple of books and searched all over the net for the last few months. BTW, just cause it's on the Internet does not mean its true...
Here is my setup
Lee Classic Turret Press w/ auto drum powder measure (auto index removed for now)
9mm 124gr round nose from Berry's (250)
9mm 124gr "small ball" with Hi-tek from MBC
Hodgdon TiteGroup
Reading a couple of different manuals I was able to run off 10 of the Berry's bullets for testing with little problem using 1.15 OAL 3.6gr of powder which is the starting grains. Shell diameter at the case opening after crimp is .375. Plunk test worked good and I even made some dummy rounds to run through the mag and chamber to check for sticking.
I do see a slight "bell" at the top quarter of the round so I need to figure out whats causing that???
My Question is with the MBC bullets and the TiteGroup powder. Starting Grain is 3.6 with a OAL of 1.15. When I do this the plunk test fails and sticks in the barrel. From what I can tell I can chamber and feed rounds fine from the magazine but I'm not too keen on failing the plunk test. I'm guessing this is due to the shape of the MBC vs the Berry's
To figure out what it could be I painted a round with sharpie and stuck it in the barrel, what I found was the bullet needed to be set deeper as it was hitting the rifling. I adjusted my press and from what I can tell the OAL that works best for this bullet is 1.10.
Because I need to set this bullet deeper this will have a different pressure on the round when fired. If I'm using the starting charge but not the recommended OAL how can I determine a "safe" load to test with?
TIA
