V-N110 in the .45 Colt

[Paden]

Yep, this thread has definitely been hijacked.  Should probably start a new thread on this in the testing forum. 

And so I am...

The conversation from the other thread:

A 350 grain bullet at 1100 fps with N-110. How much N-110? I'm using N-110 in the 45 Colt Also but with a 280 gr MP 270 SAA and LBT Blue.

It's a hair shy of 350...I was shooting for 350 when I spec'd it out, and I named it "45-350-NMB", but with Lyman #2 it comes in at 347 lubed and checked... (Large Frame Ruger Only Load!): 16.5 - 17.0 grains over a Federal Match primer (standard, NOT magnum) and Starline brass. What's your load for the 270-SAA?

I posted this on Nov 5 in this thread - Unobtanium
The Sierra manual heaviest bullet listed is 300 gr jacketed. Paden's 350 gr cast is 1.2 gr under Sierra's max load for a jacketed 300 gr. I've not tested a bullet that heavy in the 45 Colt but given that a cast bullet will build somewhat less pressure than a jacketed and his load is reduced from 1.7 to 1.2 gr it could well be a safe Ruger only load. Seems to be shooting well but only Paden can check for pressure signs.

I recall Linebaugh tested revolvers to destruction with no overtly visible signs of pressure. I would be unwilling to claim any revolver load was safe based on apparent lack of pressure signs.

Drifting tangentially from the scope of the lube thread...but I'm happy to share my spreadsheet of aggregated data used for extrapolation and N110 load development, if you'd like to scrutinize it. I think I'm safely under 32,000 cup. You very well could find a flaw in my logic, or otherwise reach a completely different conclusion.

Attached for scrutiny and comment is a pdf copy of my aggregate data from which I extrapolated my current load. I do feel I'm safely under 32,000 cup. Anyone's invited to poke holes in that theory.

pdf file doesn't open for me.

Hmmm. Have tweaked it and reloaded. Looks ok and works for me.

Worked this time, maybe it was this puter.
