Thread: FTF Question - what am I missing?

Still, the SIG P6 in question is a German gun, made for German police & military, using FMJ-RN ammo. American Sporting Arms & Ammunition Manufactures Institute (SAAMI) specs didn't have anything to do with the chamber or leade dimensions. I'm here to tell you they have a shorter then normal leade, and TC or HP bullets with a longer full diameter extending past the case mouth have to be seated shorter to chamber in...

And never have I disagreed with your assessment of that specific weapon or your point in general. I'm pretty sure my statements regarding gaging have been clear from the beginning, let's not make more of it that necessary but we can always go get the CIP standard and find out if it is different from SAAMI for the 9mm. Even more interesting, we can go ask those Germans what standard they used when chambering and rifiling that pistol....

So, after a few nights of manufacturing and a few trips to the range to test out my rounds, I think I've found my "temporary" formula: Winchester or Federal once-fired Brass: .748-.755" length Winchester Small Pistol Primers Berry's Plated HP 124gr 9mm (.355" width) Alliant Bullseye Powder: 3.8gr OAL: 1.080" +/- .003" Crimp Width: .378" This formula is the minimum powder...

Nice job on your workup, w00dc4ip. Let us know how the second set shoots with your other 9mms. If you're not completely sold on the Berry's plated bullets, you can try Montana Gold's full metal jacketed (fmj - lead base is exposed) or completely metal jacketed (cmj - base is covered) bullets at very reasonable prices (bought in bulk). https://secure3.mooseweb.com/montana.../pricelist.tpl __________________ "A well...

Thank you, Deavis. What publication is that; is it online? Have a link? added on edit: I found it; it is pdf page 29 in the online version of this manual , "ANSI / SAAMI Centerfire Pistol and Revolver" (Performance Standards Handbook). added on edit #2: I've just printed the page and will study it. It seems to me, however, that what we have for the ongoing discussion in this thread is this issue: What is the nature of...

If they won't go in the chamber, they won't shoot. It looks like you need some taper crimp on the case, at least eliminate the flare or close it down SLIGHTLY. If you stuck a bullet in the rifling, the OAL is too long. Seat the bullets and crimp to where the round will chamber FREELY and extract in one piece. Yes, shorter OAL will reduce working volume in the case and increase chamber pressure. That is what the boring fine print...

I had the same problem loading 124gr TC bullets. Initial OAL was 1.11 as suggested in my Lyman manual, but they wouldn't chamber in my CZ or HiPoint carbine. I ended up with 1.04oal with that particular bullet. And I agree about a taper crimp, really helps in my case.

Use a case gauge or a barrel and see what the max length you can load to. I load 9mm for a Sig P6. Max length for this pistol is 1.065 or it will stick in the lands. All ready said but start at the lowest charge and work your way up. For 124 gr LRN I started at 3.4 gr bullseye and worked up to 3.8. Works good in the P6. Fred

Is it possible that he might be using the wrong bullets for 9mm?

In my personal experience, Lee taper crimping dies just don't do what they are supposed to do. In both 9mm and .45ACP I've had feeding problems that were traced back to the inadequate crimp performed by Lee dies. Solved all my problems by buying "real" taper crimping dies by Hornady. I still use my Lee dies for reloading, but always finish the rounds with a Hornady taper crimp now. I would not get histerical about...
