Not long?
I didn't mean they wear out under normal circumstances, but use of non-ball ammo on a mil-spec 1911 with a GI mag will not function....... very long.
Brother, all I can say is that you musta found some pistols
made outta pot metal. Unhardened ordnance steel hits the Rockwell
"C"scale at about 28-30...The cupro-nickelalloy in bullet jacket material might go as high as 3 Rc, regardlessof bullet shape or profile..I'm afraid
you'd go broke long before you wore a feed ramp enough to cause
problems. The trouble with alloy frames isn't the bullets so much as it
is the front of the magazine follower digging in on the last round, and
even that's rare with standard followers.
FWIW, I've shot thousands of hollowpoints over the years in old
GI pistols and Commercial Colts and Springfields...Alloy and steel
frames. Never seen one stop functioning due to frame ramp wear.
I think there's something else at work with your Colt. If you'll get with
me as to exactly what it's doing, I'll try to figger out what it is and try to
get it straightened out.
------------------------------------
If someone walked into the average gun shop with a GI-1911 and tried to shoot all of the ammo that is sold behind the counter, how versatile is a GI 1911?
More than you'd think, even without throating the barrels. It has more to
do with the overall length of the cartridge than the bullet profile. Though
some profiles are more troublesome than others. Try Remington Golden
Saber or Winchester Black Talon in an unmodified GI pistol, with GI"Hardball" mags for a real eye-opener. I understand the Speer Gold Dot
is also very good.

If the gun was designed to feed more directly into the barrel
That's a question often asked by people who don't understand the controlled feed design of the 1911. The round climbs the hill in order to
let the rim slip under the extractor and keep full control of the round . That's why the 1911 will function upside down as reliably as it will rightside up...Your Beretta probably won't. Climbing that rampand entering the throat at an angle like that also bleeds off some of the slide's momentum and makes for amore gentle return to battery. If it fed with a sharp "whack", the lower lug and slidestop pin would take a worse pounding...as would the hammer and sear and the slidestop hole in the
frame.
Part of getting a 1911 to feed smoothly is in the timing of the barrel's
rise as the slide returns to battery. Correct shape of the lower lug and
center-to-center length of the link is critical, and lends itself to simple tuning
if the barrel rides the link rather than being cammed upward toward
battery/lockup by the front of the lowerlug's radius. Most people who
experience feeding problems automatically assume that it needs a ramp and throat job...and ruin their pistols with overzealous filing, grinding, and polishing as a result. The truth is that the wide barrel throat that's in
vogue isn't really necessary except for shooting semi-wadcutter bullets
and one or two styles of hollowpoints. At most, they usually only require
a small amount of widening/polishing to get them to feed hollowpoints
with rounded or truncated cone-shaped bullets.
Much to learn you have...Teach you we will...but first you must open your mind.
Tune-Fucious say: Reading gunzines, often counterproductive to one's tuning skills.
May your journey be short and your days filled with pleasant warmth
and sunshine.
