I agree with all of the reloading procedures precautions given but I think it is misplaced to blame the powder. Nor do I see much difference among the fast burning powders- Bullseye, Titegroup, etc. as to the caution required in their use. Titegroup is being marketed as an alternative to Bullseye and we see loads for almost every caliber. I've even used the load from Handloader for the 284 gr. 270SSA 45 Colt. You can fry an egg on the barrel after 6 rounds but, properly loaded, it works fine.
Titegroup has been available, in my neck of the woods, where no other pistol powders can be found. As the slower burning powders continue to become more available, we can switch back to powders that are better suited to the application at hand. However, I have to admit that I am grateful for Titegroup as a powder that has the ability to handle my diverse needs in a time when, without it, I may not have been shooting.
Well, everyone has a right to their opinion, but I will respectfully disagree. I've been reloading since 1983 and for 3 years ran a commercial reloading operation. I've run single stage to Camdex machines, and I've burned a LOT of powder. I've learned that some powders ARE better (or worse) than others.
Titegroup was marketed by Hodgdon as a "do-it-all" (usable in many cartridges for many light to medium load levels), low-charge weight (cost saving through more loads per pound), and particularly accurate (hence the name, but they quickly stopped making this claim within a year or two of it's introduction, interestingly...). As has been pointed out by others here, it burns HOT. It also is known as an unforgiving powder. I came across this latter aspect.
I learned as a commercial loader that, before I loaded 10,000 rounds of a particular load, I needed to test the powder, bullet, primer, case combination as well as searching the range of allowable variation, and that within that variation, everything was safe. In my three years, I never had a customer call and complain. So how did I find a load? Well... Ever notice how loading manuals never agree? That's due to both lot-to-lot variations (even of the same components), plus differences in testing equipment, plus minor variations in components (like using a different brand of primer or a Speer bullet, instead of a Sierra). You can also be sure that my (or your) lot of components is not the same as ANY of those labs used to come up with their data. BUT, if you look for the middle-of-the-road load from 5-6 loading manuals, you'll notice that they all get to about the same velocity. You want to find a load with YOUR set of components that gets to that velocity...
What I would do, is conduct a meta-search of all the loading manuals (I have a looooooong shelf full of them). I look for the typical velocity that tells me what my load should be producing, if my pressures are middle-of-the-road. Then I'd load my powder and I'd go for the middle of the road velocity. For example, for my 38 Spl. 158gr LRN, I wanted 770 fps after my meta-search. I loaded up 10 test rounds at each powder level (skipping about .3grs up and down in two steps), and when I found the powder charge that would give me my target velocity, I loaded over and under by 15% each. This way I made sure the 15% under-charge still pushed the bullet out, and that the 15% over didn't cause stuck cases. (It often would flatten primers, but I didn't want customers having to pound cases out with a rod and hammer...) If the powder I had wouldn't be safe at 15% over and/or not push the bullet out at 15% under, I'd move to a different powder, usually slower...
The reason I go over all of this, is because when I bought the one and only pound of Titegroup I ever bought, I ran this test with my 9mm and 38 Spl. loads. What I learned was that, Titegroup is, what I call, very "peaky." What I mean by that is that the difference between a middle-ground load and an over-pressure load is often 0.2grs in these small capacity cases. And by over-pressure, I mean flat primers on all, and pounding 1 or 2 out of 6 cases out of the cylinder with a brass rod. POINT 2 grains lower was a perfectly safe load, which gave just slightly higher than average velocities (800, rather than 770). When I tried it in 45ACP, similar problems happened, but the additional volume allowed .3 to .4 more grains before problems started.
I don't care for this. Frankly, I still have about 1/2 to 1/3 of the pound of powder, because I don't have use for a powder that acts this way. I'll probably burn it up in some 38 target loads with 148gr wadcutters, but it's just to get rid of it, because I won't use it for volume loading. Can this powder be used for effective loads? Sure. Is it forgiving and flexible? NOT by a long shot!
So, how does this involve Dutch? Well, just reading between the lines, but way back on page 2 or so, he stated he pulled the bullets on his handloads and found some cases empty and some with double charges and more. Obviously, there is a problem with the process here, because neither of those things should happen, and they are not the powder's fault. However, when you combine the process problems with an unforgiving powder, you have a recipe for disaster, and that's just what happened to Dutch. (By the by, Dutch, I am VERY happy you suffered no physical effects -- Other than nerves, I imagine they were shot for awhile. I hope their back to normal for you and you can enjoy our sport again!)
As far as the process goes, I started with a single stage press and hand-charging cases in a loading block. I was taught the age old trick of checking the loading block full of cases to see if the powder level was about the same in each and every case by going under a light and scanning each row of cases carefully. The problem on a progressive press, especially one that is manually indexed, is that the process has to be run just right, and there's no way distinct way to check one case against another for powder level. I now use a Dillon 650 (auto-indexed, so it forces the cases to move around the shellplate, making double-charging by neglecting to index impossible). Dillon sells a powder check die which sits in station 3 and can be set for your powder charge and will sound an alarm if it's too high or low. What I learned was that the alarm was too sensitive (sometimes it would alarm on the correct powder charge, or a VERY minor variation like .1gr difference), and the false alarms slowed the process too much. I now have removed the powder check die, and I replaced it with a small LED light that shines down into the case. Once you've seen 3-5 cases go around the wheel with powder in them, you can tell by eye if the powder level is about right. I LOOK at each and every powder charge I load (just like when I was doing single-stage and looking into the cases in the loading block), but I have the speed of the progressive. I've also found the Dillon measure is consistent within .1grs at pistol powder charge levels. Now, that doesn't mean I don't watch and just trust the powder measure. I STILL look down into each case and make sure there's "about the right amount" of powder in each case...
