    Looks nice. My uncle got one back in the 1960's. I fired it a few times. After that, I became a revolver guy. About 20 years ago, I ran across a nice one at a good price and picked it up. The surplus Largo ammo that was sold cheap in the 1960's...

    I have used Trail Boss for most of my 45 Colt loads. When I bought guns in that caliber, I laid in 500 Starline cases. These are thicker (heavier sides) than Remington or Winchester cases. I tried the top load recommended (but still mild), about...

    Whatever you do, don't make a "Canadian K-32". About 40 years ago, I saw a gun on a gunshow table that was labeled as a "Canadian K-32 Masterpiece". Someone had a real barrel from a K-32. I don't know if the chamber was real or if it was...

    From my experience, mixes of different materials, but with the same Bhn do not act exactly the same. Both antimony and tin raise the Bhn. But tin is better for accuracy. It is also more expensive. Antimony raises the Bhn faster and farther...

    You have good accuracy there. That means the bullet is hard enough for the pressure you are shooting at. It looks like the barrel, chamber, and throat dimensions are probably good, too. Reducing the Bhn will not change the accuracy very much...

    Back during the Obama shortages, I ran short of small pistol magnum primers for the .357 Magnum. I did have small rifle primers. I used them. No problems with ignition in several revolvers and no excess pressure signs. Used them for 3 or 4 years.

    I have never understood why people use hollow-base bullets in guns with correctly sized groove diameters, cylinder throat sizes, and chamber diameter. I have used hollow-base in some guns like that, but did not see any increase in accuracy with...

    Harry O replied to a thread Goex VS. Swiss in Cast Boolits
    I started with GOEX because, at the time, that was about all there was. When I got my first pound of Swiss, I never looked back. GOEX requires much more powder compression (almost solid). It requires more lube (it burns dry). It also leaved much...

    Sent by PM The original groove diameter of .38 Short and Long Colt guns was 0.375". The original bullet diameter at the front was the same (0.375") with a heel-base bullet of 0.357"-0.358" diameter at the back end to fit inside the brass case. ...

    I would not recommend putting ANYTHING between the powder and the hollow-base. Not a card and not filling the hollow-base with BP lube. I have shot many thousand hollow-base bullets in my 41 Long Colts and tried both early on. They made accuracy...

    Harry O replied to a thread 38wcf or 44wcf in Leverguns
    There have been discussions about 38-40 vs 44-40 from time to time here. Usually someone mentions (like me) that the 38-40 seems to be more accurate than the 44-40. I just got the latest Handloader magazine. In it there is a Mike Venturino...

    Outpost75: I have a number of 38-40 moulds (with and without crimping grooves), and most of them don't work with my rifle. I am not sure from your drawings, but it appears that they will not work either. I am using mine in a 1873 Winchester 38-40...

    I have wondered about that from time to time, myself. Of course, there was not much in the way of wheelweights back then (pre-WWII in Idaho). He does not mention them in the book. He does mention them in the magazine columns, and does not think...

    I totally agree on this. High antimony/low tin bullets are bad news. My rule of thumb is put as much tin in a bullet as there is antimony already in there. I know some people here put one-half the amount of tin as there is antimony. If it works...

    Maybe I overstated that just a little bit. Read the last part of the chapter called "A Bullet Chapter". He goes through the usual suspects if leading occurs (too hot a powder, undersized bullet, etc), but adds the following: "some leading will...

    Harry O replied to a thread 38wcf or 44wcf in Leverguns
    I also have, and use, both the 44-40 and 38-40 in rifles and handguns. I started with 44-40 for CAS, but the varying dimensions meant that nothing I tried was accurate in all my guns. That was because of the mixing of 44-40 and .44 Magnum parts in...

    My son gave me a copy of the book “Sixguns” for my birthday recently. I first read the book by checking it out of the library in the mid-1960’s. I bought a copy of my own 10 or 15 years later. Still have it. So, obviously, it was time to re-read...

    Harry O replied to a thread Starline 375 Win? in Leverguns
    I once had a bunch of new 30-30 brass and .375 Winchester brass together at the same time. I decided to see if the claim that .375 brass was heavier was true. I weighed a bunch of each and compared them. The .375 Winchester brass was a little...

    Something I remembered that might help someone here. Back when I got my Stars, I spent some time at the gunshow table of a guy who specialized in magazines. He had 4 magazines for Stars: 1) A model, 2) B model, 3) Super A model, and 4) Super B...

    The Starline brass is the best thing that has happened to 9mm Largo owners since they were being sold for less than $20 through the mail back in the 1950's. The first one I shot was an Astra belonging to my Uncle. I got one shortly after. After a...

    If you want full power .357 Mag loads, I recommend (and use) the 358156 with a gas-check. If you are going to download them to between .38 Special +P and full-power .357 Mag loads, use the Keith 358429 plain-base. My MKIII Trooper likes slightly...

    I am a 32-20 booster, but I have always thought Ruger had it right using the .30 Carbine cartridge in a heavy single-action revolver. The reason is the thickness of the brass. I don't shoot very heavy 32-20 loads in my revolvers, but I also have...
