Run in Quickload real quick

jwrowland77 · August 30, 2012, 10:39 AM

I was wondering of someone could run this in Quickload for me real quick.

9mm
Win case trim .750
CCI 500
Unique 5.9
OAL 1.157

I was getting ready to go test it shows safe in the manual but just wanted to see if someone could check through Quickload.

What bullet (type:jacketed, plated, cast or swaged + weight in grains)?

Oh sorry. Win 115 FMJ RN

The QuickLOAD database doesn't have the Winchester 115 gr FMJ RN in its bullet database.

I tried it with several 115 grain FMJs by other bullet manufacturers, but the results vary a LOT because of substantial bullet length differences. Results ranged from 31,000 to 42,000 psi with the other parameters besides OAL set to default values.

So, please measure your bullet length and get back to me.

They are definitely 1.157. They were 1.164 but I had to shorten due to feeding issue.

It is not the cartridge OAL that I am missing. I need the length of JUST the BULLET so that I can calculate the seating depth and the space remaining for the powder. That plus bullet weight are the main parameters that affect the pressure in a specified cartridge with a specified powder.

Ah ok. I'll measure that real quick

Length is .56

Sorry, you posted the length while I was responding to "Yes" without the length, which you then edited. Now I find that I can't edit my last post.

Anyway, using a bullet length of 0.56", I get 35,528 psi.

That is just above the SAAMI standard pressure limit, but under the SAAMI +P limit.

Howeveer, QuickLOAD is not very accurate with just its ddefault values, and usually over-predicts pressure without getting things like your actual case capacity. The more useful information is probably the CHANGE in pressure that results from the shortening of your COL.

For your original COL of 1.164, I get 34,560 psi.

So, shortening your COL raises your pressure by about 1000 psi, which is less than the typical cartridge-to-cartridge variation with the same load on actual pressure testing equipment.

Ok sweet. Thank you much for your help.
