Kaboomed Marlin: RL7 is NOT AA#7!

Marlin 444 reloader Kabooms a rifle by buying Accurate Arms #7 (handgun powder) instead of Alliant Reloder-7 (rifle powder).
Says I need to be logged in to see the pics. But-
Luckily I was using a rest and not my left hand on the forearm. Pieces if the walnut forearm penetrated the shooting bench. I really thought I had found the powder everyone was saying I needed to use.

This is why more companies should put more example loads on their labels like Hodgdon does.

It's a bit weird that some companies merely use a 4 digit designation for their powder without a sample of what types of loads it could work it. Not that I'm making excuses for this guy, but when you're browsing the powder aisle I'm always drawn to Hodgdon powders since they give examples of what types of suggested loads could be right on the label. At least I know it's a rifle or pistol powder.

a few positives here , he learned from his mistake without injury ,and he admitted his mistake

one thing i noticed ... no mention of a loading manual anywhere
after reading that thread and a few of his other posts i gather he may have gotten his reloading data from an unpublished source .. mainly the internet via a forum . and this may have caused his confusion on the powder issue.
how ever i have no way of knowing that for sure so i can not condem him for that .

there is a fool proof way to avoid these mistakes ... never ever think you are right . know you are right .
loading manuals are very clear on what powder to use and how much of it to use . and they are a very reliable source .
random people on a forum ... not so much

I've never used a load mentioned by some guy on a forum without at first reality checking it against my multiple loading manuals. Someone says, "yeah, 3.0 grains of Bullseye give great accuracy!" Well, if the book agrees with that load, I may try it, but certainly never without confirmation.

Yeah, sorry... or wait, not sorry. I simply can't find fault anywhere here with anyone other than the amateur chemist who thought he was a skilled handloader. Cannot & will not ever subscribe to even a hint or partial notion that ANYONE could have done anything different to "help" a moron to avoid hurting himself.

It seems to me that if he hadn't grenaded a rifle that day, he might just as well have gone home and drank paint thinner because he assumed that might also be a good idea to work on that indigestion he's had. :roll:

There are many pitfalls in the hobby of handloading, we build and execute a process of checks & balances to counter those pitfalls. This guy didn't make a "mistake" similar to one of the pitfalls we often see at a load bench, this particular person should NOT HAVE BEEN RUNNING A LOAD BENCH.

It's not for everyone, there's no shame in that. I wouldn't want this guy doing electrical work in my home or working on gas lines, either.

I recently had to buy some powder for my 308 loads. I looked at my load card, and it said 4895. I knew there was an IMR 4895, and Hogden 4895. So I went to my manual, and it reference IMR 4895 for the load. I checked a couple other sources to confirm IMR 4895.

Before I went to the store. I took a photo with my cell phone of the load manual, so I could reference at the store, and not buy the wrong powder.


This idiot would have saved himself alot of trouble and expense by doing something similar.

The old man that taught me reloading re-inforced checks. As in check, re-check, re-check, re-check, re-check, re-check, re-check, re-check, and if necessary re-check. Don't assume its right.

Your process is much more what he should have been doing, but I would hedge a bet that you knew that IMR and Hodgdon 4895 are certainly not the same powder, but they are AWFULLY close powders.

The two powders this guy interchanged couldn't be all too much more different.

It's like the recipe calling for a dash of salt and the cook instead dumping in a quarter-cup of strychnine. :shock: :x

The guy who did this bought & paid for the outcome and he absolutely got his money's worth. :|

This. ^^

I have been known to ask for favorite loads and such, but would never, ever, use them without checking them against multiple published sources. And I never, ever, rely on memory when loading. One container of powder on the bench at a time, one box of primers on the bench at a time, one box of bullets, etc. Sitting beside those items I'll have my desired load on an index card, freshly double-checked against the most current manuals I have. Then check caliber, powder, primer and bullet weight before beginning.

Why yes, I've been known to wear both a belt and suspenders, why do you ask?
