A stuck bullet from a reduced charge more likely will cause a bulged barrel, a round fired on top of another will not guarantee a blown up gun.Your credibility just went out the window on that one.
What you probably saw was a bullet stuck in the bore and another round fired on top of it that blew up the gun.
I use H110 in 44 Magnum, 45 Colt and 454 Casull. I've stuck bullets in the barrels of all three calibers because of reduced loads.
I've shaken out large clumps of unburned powder. I've had bad ignition where one round went off as normal, but the next round just went poof with a lot of smoke.
I've loaded H110 so low that if I didn't notice a new hole in the target I immediately rodded the barrel to check for a stuck bullet.
Most of my H110 loads are 1 to 1.5 grains below the minimum listed charges. I've been doing this for many, many years and thousands of rounds.
Where's my detonation?
Because I wanted to know for myself about downloading H110, instead of relying on internet posters who mostly just repeat what they've heard others say....My question is, why would you purposely load H-110 so low, especially after having previously stuck bullets in 3 different calibers with using low charges of H-110 ? Why not just use a faster burning powder for reduced loads ?
