The load data I used has been extensively tested by the owner of it, EliteAmmunition.[/quoted]Tested how? In an instrumented test barrel, measuring the maximum chamber pressure? Or did he just make up some loads, shoot them in his gun, it didn't blow up so he called it good?
Recipes in reloading manuals have been tested in instrumented barrels. Stick with them.

In March, 1955, plaintiff bought a nationally advertised, name-brand Winchester Model 70, .220 rifle. He removed the standard barrel, replacing it with an abortive one of different size and caliber, made by an unknown local gunsmith, whose genius or capability is not reflected in the record. With this hybrid substitute for the standard equipment, plaintiff was fortunate, nonetheless, to survive the firing of 150 to 200 rounds. Early in 1956, plaintiff's genius for disaffection from using the gun under normal, standard conditions, led him to seek and have another unknown Reno gunsmith resize the barrel to accommodate a longer cartridge, and to place a new stock on what, a year before, had been a standard, nationally advertized firing piece. At this juncture only the middle of the original rifle remained factorywise. It is not quite clear why this portion of the firearm had not been replaced by the gunnery idiosyncracies of the plaintiff.
Plaintiff not only was a tinkerer, but a ‘handloader,’ obviously harboring an indisposition to use standard ammunition, and entertaining a bent for manufacturing his own unorthodox slugs. Such ammunition, undesigned for the gun he bought, and unknown in the market overt for use in the now newly calibrated, converted, blunderbuss, nonetheless was employed by plaintiff. After using these home-made, overstuffed, undesigned, unrecommended cartridges filled with faster-burning, more explosive and more highly pressured slugs than ever had been used before, his luck ran out after firing but two rounds. On the third, the middle of his rifle blew up, removing part of his finger which, I suggest, the defendant involuntarily purchased through the agency of what I consider to have been a wholly unreasonable jury.

shocking FN allows the 5-7 to be market with an inherent flaw like that.
count your lucky stars buddy, you could have came out with a lot more damage than that. hope you were wearing saftey glasses.
hope everything heals up fine.
Double Naught Spy, congratulations on your purchase of a pencil....but there was no attempt to line up the cartridges.
Overall length wasn't my point. It's seating depth of the bullet.
Kindly take a note of the cannelure visible in the one round, and consider that the cannelure in the second is buried inside the case.
This could be a "one in a million" failure, or a "bad batch" of manufactured pieces causing the failure, or a design flaw that will reoccur repeatedly... or "bad mojo" at this point... no one knows until the pistol is examined and some experts figure out how it happened (first) and then "why" it happened. Everything else falls in place from there.
