Its been a quiet night so here is a discussion starter. I thought I wanted a .44 revolver for my next gun. I quickly decided I did not like shooting .44 magnum with a lightweight revolver (Taurus Tracker) and that a heavy S&W didn't fit the primary hiking application. Realizing I was going to use only .44 Specials I started to compare ballistics and came up with these numbers from the Speer website. Of course I have them all plotted in excel but can't figure out how to post that and why can't I get these numbers to line up? (I've attached a pdf of the plot)

Speer Gold Dot Ballistics fps ftlbs

44 mag 240 gr 1400 1044

44 sp 200 gr 875 340

45 ACP 5" 230 gr 890 404

45 ACP 5" 185 gr 1050 453

45 ACP 4" SB 230 gr 820 343

45 GAP 4" 200 gr 970 418

45 GAP 4" 185 gr 1090 488

When I saw the low energy numbers of the 44sp I started to compare the two .45 numbers that I know. Here are my presuppositions along with unexpected findings . . .

- ignoring the platform question, revolver vs auto or even which auto

- handloading is not an option at this time

- the potential application excludes grizzlies so .44mag is not required

- heavy grain .44 or .45 is preferred over smaller calibers

- all .45's exceeded the .44 special energy numbers

- barrel length is very important to ACP

- ACP does much better with 5" than 4"

- my 4.25" 1911 is equal to the .44 special (ok but not good)

- the energy numbers imply an efficiency advantage for the GAP

- the loadings wring more energy out of a 4" bbl in GAP than ACP

- I could go for a full size 1911 or since I used to own a G38 maybe its time to come back

Your thoughts?
