Reloading specs for 160 gr Hitek bullets in 9mm with W231?

[Caligula36]

ICORE is 120pf unless changed.
It has been a while since I've been active, although a life member.

Typo. Yes it is 120.

I'm wondering, is it preferable to taper crimp plated bullets?

Only 3 grains of N320 or 231? Woohoo. I have enough powder to load more rounds of 9mm than I've shot in my whole life.

Don't know if directed to me, and just my opinions below. Lots of discussions around crimping.

In handguns, yes, especially semi-autos. If there is a crimp groove in the bullet and used in a revolver, then a roll crimp would be preferred IMO.

General notes, not directed at anyone:
As some have noted above, 9mm pressures can go up quickly with fast powders, or reduced case capacity due to bullet setback/seating depth. IIRC there's a note in an older Speer manual that pressures doubled when a bullet was seated .06 deeper (that's a lot for those that don't know). A bullet could set back a bunch in a semi-auto if not properly crimped..

So many people out there getting started just learning how stuff works. I think it's good to have lots of manuals and cross reference.

Clays pressure goes up quickly in smaller cases like .40 with heavy bullets. Similar powders would do the same.

Interesting. I've been looking at the Bayou 160gn RN. 158gn cast RNFP took 3.4gn of Titegroup to get just over the 120PF for ICORE.

Does the difference of using a roll crimp on cast affect the results? These Bayou bullets do not have a canalure for a roll crimp.

I'm loading .38 short colt, not .38 special. Huge difference.

Roll crimp or taper crimp is fine, either one will work. I use either one depending on if I want to change my crimp die, or not ( mostly not).

I bought a 12# jug of 452AA back in the 80's. Many, many thousands of 32SWL, 38Spl, and 45ACP. Admittedly, there was a long break from shooting, but I finished the last of that jug a couple of years ago.

I won't be around anywhere near 40 more years, so I'm good. With respect to 9mm powder anyway.
