I've just loaded about 200 rounds of .45ACP; 185gr JHP's over 6.2gr of WW231. My Hornady "LoadNotes" book gives the Cartridge Overall Length as 1.230", yet my Lyman manual gives the COL as 1.175"..why the discrepancy?

[Original info deleted. I thought the two bullets in the two manuals were different, but they're not. They are both Hornady 185 gr. XTP/HP's. Good question.]

Speer Reloading Manual #12 shows--

185 gr Gold Dot JHP with COL of 1.200"

185 gr TMJ match SWC with COL of 1.275"

200 gr TMJ match SWC with same COL
(This is like a plated H&G #68.)

200 gr JHP with cannelure, with COL of 1.155"
(This is, I believe, the old "Flying Ash Tray" with huge hollow point.)

200 gr lead SWC with COL of 1.185"
(This is like a swaged lead H&G #68)

Hope this helps - - -

Mike,

You may want to give Hornady a call. When I've called them in the past, they have always been very helpfull. They even put me through to Steve Hornady with what turned out to be a really silly question.

Good Luck...

Joe

Thanks..my 'latest' Speer manual is #11, and it doesn't even show a 185gr JHP load..only a 200gr JHP.
I've decided to stick with 1.230" and run them through my 1911 this evening. I loaded my 200gr lead SWC's to a C.O.L. of 1.245", so the 185gr JHP's are a bit shorter. I'll let you know how they go!

Thanks...I'll give them a call. I use a lot of Hornady equipment when reloading, so I guess I'm a 'customer'..<g>

Well..I fired about 150 of these rounds this evening. I had one stoppage (VERY unusual for my Norinco 1911A1). It was a last round from a suspect magazine, so I'll discount it..the round half-chambered at an angle and stopped the forward moving slide with the chamber half open..there is a distinct 'cut' in the cartridge's case about 1/8" from the case mouth where it caught the chamber throat.
The rounds chrono'd at between 846fps and 896fps, which was good..the Winchester loading manual gave the velocity as 915fps for 185gr JHP's over 6.2gr of WW231. To achieve Major velocity, I need at least 920fps, so I'll up the powder charge to 6.4grains, which should do it. I found the muzzle flip was a bit more than usual. My 'usual' load is a 200gr lead SWC over 5.7grains of WW231.
