    I have been using Large Pistol Primers in both 38-40 and 44-40 CAS loads for 30 or more years without any problems of any kind. If you are planning to use +P loads, that might not be a good idea, but with standard pressure loads, Large Pistol is...

    Harry O replied to a thread Load data for .40 - 65 in Leverguns
    From SPG Lube book by Mike Venturino & Steve Garbe: 40-65 Winchester formed from 45-70 cases trimmed to 2.10" long. No special dies needed. Groove diameter from 0.403" to 0.409". Slug to find out. Bullets cast from 30:1 lead:tin mix. SPG...

    310gr depends on the rifling twist. And also the pressure you use it at. Might work. Might not. I have a mould that works, that I have used for high power loads in a newer 44-40. It is the 429215GC. That is a Keith style semi-wadcutter, cut...

    I went to SR4756 as soon as I tried it in the 32-20 (from Ken Waters book). It was great in a 32-20. Better than great. I am nursing my remaining SR4756 for that caliber only. I also have a number of .32 Magnums and, before SR4756 was...

    To be just a little more specific: The DA charged my kid with "felony terrorism" with a possible 20 years to life. I was in the courtroom and heard the first judge tell the DA that he did not have any case for felony terrorism. At best, he had a...

    I have a number of microgroove barrels that I load for in different Marlins. Slug the barrel to find the ACTUAL groove diameter. One or two thousandths over that is fine. I also found that a slightly harder bullet works best, too. Bhn 10-13...

    I had a Rossi 92 in 44-40 many years ago. From memory, the barrel was on the large size even for a .44 Magnum barrel (0.431" to 0.432"). Fortunately, the chamber was large enough to take a 0.432" bullet. With the large bullet, it was accurate...

    The only thing that people here should be looking at is the DA in their jurisdiction. If the DA is a pr*ck, he will bend the law to nail you, regardless of what kind of ammunition you are carrying, what kind of gun you have, and what stickers are...

    Harry O replied to a thread 44-40 +p? in Leverguns
    My Rugers were bought right after they were introduced. I did send them to a gunsmith to ream out the cylinder throats (in front of the chamber) to 0.430" (up from 0.424"). Unfortunately, he did not have a chamber reamer to open up the necks of...

    No. I tried that. From post: "I even got another neck expander and took the diameter down some to get more tension."

    Harry O replied to a thread 44-40 +p? in Leverguns
    This is not about exactly what you are thinking of doing, but you can use it as a data point. I originally tried CAS with 44-40's using a Marlin 94, Rossi, and a couple of Ruger Vaqueros. All were new production in the early 1990's. Because of...

    I also have a 30-06 BAR (the second model with the BOSS) and a couple of Garands. I have used Garand loads in the BAR without problems. The small base dies were mentioned above. When reloading, I could tell the cases that were fired in the...

    Harry O replied to a thread Help with .44-40 in Cast Boolits
    If you plan on using smokeless powder, DO NOT use the 42798 or 427098. With Remington or Winchester cases, you cannot get enough neck tension to hold the bullets in place. Starline cases seem to work better, but I have not used them enough to tell...

    Random notes. 1) Pretty much all of my .32 H&R Magnum firearms give lower velocity than what is published, including with factory loads. I did not know the details of how the numbers were arrived at, but suspected it was something like the...

    The MkIII seems to be in the weight range of the S&W L-frame and the Ruger GP100 (I have all three). A little heavier than the S&W K-frames or the earlier Colt Trooper. It has a slightly smaller groove diameter (like all the .357/.38 Spl Colts I...
