Colt New Service, 45 Long Colt

attachment.php


My 1904 Winchester 92 38-40 is getting 25kpsi H110 loads with jacketed 180 gr 40 cal bullets.
It kicks like a 30-30.

My 1920 Colt New Service 38-40 is getting wimpy ammo...3 years and I have not test fired it, uh oh.... wimpy as soon as I load some
 
Boy, oh boy, large framed DA's, Colts too, the Canadian RCMP used them for quite some time also.
I also have one in .45ACP, or .45 Auto Rim, checked # & seems to built in the 1920'.
It was my grandfathers until he passed it on to my father, then down to me.
I do have a accuracy problem with it, I'm all over with it, cast or jacketed, doesn't matter, I have to spend some time using some light loads, off a rest, just to see where point of impact is, compared to point of aim , up close & work my way back to 25 yds.

Off subject, but who makes grips for old Colts ??
I also have a 1953 Dective Special, large D frame, Colt changed frame size to a smaller one, I've hit a dead end.

Thanks for the time. EK out !

Anyone reading Jim Watson's post about .38-40 should read it all and remember that (unlike other "38" calibers), .38-40 actually uses a .401" bullet. So a .38-40 cylinder needs to be accompanied by a .38-40 barrel and vice-versa
.

Ah, true...................up to a point. A .38-40 cylinder may be well mated to a .41 Colt barrel, both cartridges taking .401" diameter bullet.

Old timer Pop Eimer used both .38-40 (.38 W.C.F.) and .41 Long Colt barrels for his .401 Eimer rounds, and similar wildcats. Local gunsmith, the late H.S. Highsmith made up many .401 Specials on New Service frames, using .357 Magnum cylinders rebored and mated to .41 or .38-40 barrels. While Eimer used .401 Winchester Self Loading brass, Highsmith used .303 Savage cases.

Correct on that, Bob. .38-40 and .40 Colt are both .401 caliber.

(Now for the speculation department: Why did Winchester call it the .38-40 when they knew it was .401? To prevent confusion with other .40 cartridges? The .401 Winchester had not come out yet.) ;)

There was once an Internet Speculation that the .38-40 was really a .40-38, launching a .40 caliber bullet with 38 grains of powder. But my 1901 catalog shows the standard load to be 40 grains of black. Only the specific product for the Colt New Lightning rifle was loaded down to 38 grains.

I have read that .38-40 = .41 LC = .401" barrel is not always the case.
I think it was a Mike Venturino + Hank Williams Jr. article that reported .41 LC barrels, when marked "41" in small print were often .408" and would not make into a very good .38-40 by cylinder change.

There was once a gunsmith who offered the service of rechambering orphan .401 Herters to .38-40.
