Marlin .45-70 blow up
Don't know if these have been posted here yet. Found these at trapshooters.com
Seems the guy doing the reloading mixed up his bottles of Reloader 7 and Accurate No. 7 and grabbed the wrong one. 48 grains of the wrong powder and a touch of the trigger later.... destroyed the Marlin, lost part of two fingers and tore up the meat of his palm. Lucky it wasn't any worse.

On the Leverguns coverpage under articles there is one about blowups for those that haven't seen it.

I doubt it was found in the woods. It takes bare gun steel virtually minutes to rust once it's exposed to wet weather, or blood. I'd guess it was one of those that id the rust, as it would be way rustier if it sat in the woods outdoors.
Looks like a candidate for the Darwin awards.

The QuickLOAD simulator can make an estimate, but it is not likely to be spot on.Charles wrote:I wonder if anybody could estimate the pressure of such a mis-load?
I'll assume the shooter was throwing charges, that is, the charge of AA#7 was equal in volume to 48 gn of RL7. I'm assuming this because if he was weighing charges, he would surely have noticed he was using the wrong powder.
Looking at Alliant's data, 48 gn of RL7 suggests the bullet was likely 300 gn if he was trying to stay within SAAMI pressure specs. However, he might have been using 350 or 400 gn and trying to use pressures over SAAMI. Sticking with the 300 gn assumption, QL estimates a pressure of 37 ksi for this charge. Switching to a like volume of AA#7 gives over 52 gn and 124 ksi.
Running similar numbers for 350 gn bullets, QL estimates 45 ksi with RL7 and 144 ksi with AA#7.
Don't put too much faith in these pressure estimates. Alliant's data suggests the pressure with RL7 and 300 gn bullets would be in the mid to upper 20's, not the 37 that QL predicts. Instead, we might say he was running on the order of triple the pressure he usually did.
