.45 Super upgrade

I've been wanting a Kimber TLE/RL stainless 10mm for
a few years, but they only make it in "black". I emailed
them and was told to buy The Eclipse model, but I don't
like that model. I've looked at all the other nice stainless,
10mm 1911's on the market, but they're all over $1200,
and even for $1200 you get minimum features.

So I said, "SCREW THIS" and converted my Kimber TLE/RL
stainless .45 acp to .45 SUPER, which gives close to the
same ballistics as the 10mm; using Underwood .45 Super,
185 gr XTP/JHP's I get 1300/700 power, which matches
10mm 185 gr rounds AND I only needed to add $28 worth
of parts to my pistol.

Parts -
1. 22# recoil spring & extra power firing pin spring $7
2. 25# mainspring $6
3. Flat firing pin stop plate $15

AND for added dependability I use 5% higher power magazine
springs, which increase function/reliability; especially using the
8 round followers in my magazines.

ALSO, to fire "lesser" .45 acp rounds I just need to easily switch
to a 18.5 recoil spring.

This setup in my TLE/RL fires like "butter" and (by the way) you
do NOT need a "fully supported/ramped barrel", like so many of
those with no real knowledge tell you online. The .45 Super cases
are plenty strong, and there is no "bulging" of the case. Now if
you wanted to go even hotter than the factory rounds, it would be
a good idea to go with a ramped barrel.

Underwood makes the best "higher power" rounds, in my opinion,
in several calibers, and charge HALF of "others" ammo. The nickel
cases, cannelured/swagged bullets and smokeless/low flash powders
are great. I also happen to think the XTP bullet is the best all around
available today.

I have a S&W 645 and a 4506 that have been upgraded to .45 Super.

I think that the round really shines with heavier bullets. After quite a bit of experimentation. I have found that the Sierra 260 grain jhp, bullet # 4481. That this on top of 8 grains of Power pistol. This is the load that I have been looking for, a game load obviously. This will basically turn a coyote or a wild hog inside out in fairly short order.

I have not been able to Chrono this load to date. But field results are impressive. And yes Walter tends to go off of his meds from time to time.
