Be sure to feed some sample rounds by headstamp (Note different case wall thickness) from magazine to ensure you are not experiencing bullet setback that could compress powder chrage.
I use that setting because it was directly out of my Lyman manual. I have not experienced setback that I have observed but if 1.10 is proven to be better why not use it. I cant immagine it will do much to my load, thanks for the heads up.
Published load data COL/OAL vary because test barrels they used to measure chamber pressures have different leade (Space bullet jumps from case to start of rifling). And since most universal barrel fixtures used for testing are single shot that do not feed from the magazine, us reloaders must determine the OAL that will work in our pistols/barrels/magazines.
i did a deep dive into your last article on seating depth. Tons of great testing and information. The case data was most interesting. I wonder if different dies make a major impact. I can't imagine that a carbide die does a taper like the old all steel dies did.
Lee carbide sizer is tapered and with radiused die opening, will produce smooth resized cases like these - https://www.thehighroad.org/index.php?threads/9mm-resize-die.863126/page-2#post-11381953
Do you use the same OAL for all your 9’s or do you adjust for barrel length, bullet type, etc? A standard OAL would be great, just as one powder would as well, I’m still looking for that combo!
Reference this thread to give you a good idea what working OAL will work in multiple barrels/pistols using different brand/weight bullets - https://www.thehighroad.org/index.p...g-oal-col-for-reference.848462/#post-11068318
Same here. While many reloaders don't like Titegroup because it burns hot and violent, I do like Titegroup for 9mm as it produces greater accuracy than W231/HP-38 - https://www.thehighroad.org/index.p...e-pistol-reloaders.746062/page-2#post-9382933
I only have one 9, but several 357's. I load them all the same for now.
Have to try Universal in my Hornady measure, my old Lee Pro Autodisk meters it fine in >4gr charges if there is a disk cavity that throws what you want.
Steve, I’m using the pistol rotor. This Universal powder is really tough...and I believe it might have been caked up. I finally decanted a pound into a separate container, poured it via a case funnel, and it appears to flow much easier now. At the start it felt like I was chewing through asphalt...it took incredible force to rotate the rotor to pick up a charge. I actually put in the rifle rotor at one time, hoping the larger opening would make dropping charges easier. Nope...it was even worse. Since it’s not a stick powder the rotor does cut through these discs easily. Since I can’t drop powder reliably I am dropping a slightly lower charge, then trickling up. It is a time consuming process, but at least I know my rounds will be remarkably consistent. I only wish I had a chronograph...I’d love to see sd numbers on these rounds.
Funny you mention this. The 100 9mm loads I just completed were 124gr JHP, just a bit different profile from the XTPs. I loaded to 1.125”, whereas you’ll need to seat the XTPs to about 1.075”. Nonetheless, though I had to hand measure ever charge, 4.8gr Universal is a really nice charge for this projectile. Steve’s Pages lists Universal from 4.0gr to 5.3gr for 123gr to 125gr projectiles. I ran a ladder from 4.7gr to 4.9gr out of my Kimber Micro 9, and 4.7gr was nice, 4.8gr more accurate, and 4.9gr a bit aggressive for plinking. So I’m adopting the 4.8gr load as my favorite. Of your listed powders I only have Universal.
