  1. A COL in a manual is NOTHING more than the COL they used for their tests of a specific bullet. COL depends on the bullet shape, the barrel free bore, and magazine length--none of which the manual knows of in your case. You don't have their chamber and probably not even the same bullet. After you seat a bullet, always push down on the bullet with thumb pressure. If the bullet moves at all, reject that load. Many times, the case walls are too thin. I throw these cases away. For use in a magazine, I start at the max COL that fits the magazine, then feed and chamber an inert dummy round. If it cycles, that is my starting COL. For a single shot, so far all my guns prefer a bullet that almost touches the lede/rifling, so I start with that COL and work up a load. Usually, the test COL is close to being too short, so they get higher pressures quicker for a built in safety. This short COL will "work" for most bullets of that weight.
  2. Get 20/40 corn cob media from home depot or such.
  3. My experience: Magnum primers in std cartridges will lead to lather group sizes Std primers in Magnum loads will lead to poor ignition and larger group sizes Rifle primers in Pistol loads will lead to some/many/most rounds not going bang on first strike due to light firing pin impact. YMMV
  4. I used Precision Bullets coated bullets, but mostly I use std. lead bullets. Precision has the advantage of being swaged for consistent dimensions and weight. I have not found ANY powder faster than AA5 to be truly accurate in 9mm at distances of 25 and 50 yards. If you shoot inside 20 yards, powder and bullet selection is not that critical.
  5. 124-125gn Lead bullet in 9x19: 5.1-5.2gn Unique has been fairly accurate and 6.0gn Unique (be sure to work up to it) has been fairly accurate. Of course, no where near the accuracy of Power Pistol or Silhouette...
  6. For 124gn Lead bullets, my manuals show start loads ranging from 3.8-5.8gn and MAX loads ranging from 4.5-6.0gn. Your max load will depend on your lot of powder and your components. I would run 3.9, 4.2, and 4.5 to start with, and go up if loads seem weak. I know that my lot of Unique does fine with 125gn lead bullets and 4.0-4.5gn of Unique, and I can go up to 5.5gn of Unique, but accuracy is terrible.

  8. Take a sport that involves fast shooting, a revolver, and a squib. They don't even have the time to think before the next shot is going off.
  9. Easiest to shoot what you have. You can order as-cast, non-lubed bullets (if you aren't going to cast your own) and save some money you can put to the powder coating. Never tried, but Mineral spirits, turpentine, Simple Green and such will dissolve it--but not quickly. Heat and soak or, maybe, you could tumble (but most wet tumblers could be attacked by the solvents). Heat them up slowly in toaster oven and allow the lube to melt.
  10. >If you use jacketed load data for cast bullets you will be safe. That is if you have a 115 grain cast bullet you can use 115 jacketed load data without issue. The reason is cast bullets do not generate the same pressures as jacketed is because the cast bullets are softer. Where did you get that idea? Look at jacketed vs. lead data and you'll see that, yes, the lead data reaches about the same velocity and the same pressure, but almost always with LESS powder. That seems to imply that pressure is going up faster with the lead bullet than jacketed. Again, if you look at any magazine that compares loads, you'll find that for handguns and rifles at less then 400 yards, there is almost NO correlation between SD and accuracy. You are almost certainly throwing away a lot of very accurate loads by looking ONLY at SD. If you do an external ballistics calculation for the various velocities, BC, and Sec. Density, you'll find that over a normal spread of velocity, the bullets are all following the same trajectory--for handguns, out to at least 50 yards and for rifles out to at least 200 yards.
  11. .32-20 and .32 S&W Long. Only shoot the .32 S&W Long with full wadcutters in target semi-autos and it's only good for about 35 yards, but nice and accurate at 25 yards. Fun little things, but pretty useless.
  12. What exactly will a chrony do? Unless you know how velocity for the SAME load compares between your gun and their test gun, velocity really tells you very little. Any change in any component can have an effect on pressure/velocity--including the lot number of powder used. The two real uses for a chrony are (1) to achieve a specific power factor for action pistol sports and (2) to generate external ballistics for long range shooting. If you are shooting a XXX gn lead core jacketed bullet, then use the data for the same xxx gn lead core jacketed bullet as in the manual. This is why you start at the start load and work up. If you have a plated bullet, the standard has always been to use lead bullet data. I prefer to check several manuals and use the lowest starting load. If you look at the number of bullet manufacturers out there, if you HAD to have specific data for each bullet, reloading would not exist as no test lab can test all bullets. It used to be that manuals had load for "jacketed" bullets and for "lead" bullets and that was all any one needed.
  13. 1) It is the same as HP38, but usually costs more 2) It is the most accurate powder I have found for .45 Auto, with Bullseye, Red Dot, and AA2 being close. 3) It works fine in all handgun cartridges, but obviously won't give the same performance as 2400 and 296/H110 in magnums.
  14. My post woman hates when I get bullet orders in the mail.
  15. It can also be used internally by the manufacturer to identify certain loadings. I have a lot of cases with two cannelures and one with three cannelures. Sometimes you can "guess" that a .38 Spl case was used for wadcutter ammo as the cannelure about 3/4" below the case mouth. In jacketed bullets, a cannelure is for the case mouth to be rolled into for a roll crimp. Lead bullets have crimp grooves you can't miss. Why are "what is this ring" questions suddenly popping up in so many forums?
