Flounder' 500 Grain Boolit
Range was 25 yards. Powder charge was 80g Blackhorn. A wad was used between the boolit, and the powder. The boolit destroyed the first two jugs, and left a hole in and out through the next two jugs. The boolit was captured by the fifth jug.
The powder charge of 80g is a way plenty for this boolit. The primer from the first shot could barely be removed from the breech plug using fingernails. The primer from the second shot required a tool to remove it from the breech plug. The primer from the third shot was really stuck good, and was a struggle to remove from the breech plug using the tool. All three primers leaked right through the primer cup. Before shooting any more of these boolits from Art, and some coming from Ed, a 5/32" drill will be used in the flame channel of the breech plug. Hopefully this will reduce enough of the pressure on the primers, so they can be removed without a struggle.

Ron,

You are correct especially with BH. Your 80 grain load is a full hunting load with that bullet or actually most any bullet over 350 grains. Properties of 'progressive burning' BH approach maximum efficiency of the bullet.
IMO using 80 grains of BH on that bullet would be comparable with using 120 grains of BH on the other bullets you have been testing - sort of screws the testing process as far as comparisons.

I'm betting 80 grains BH with that 500 grainer made you see some stars for a second or 2.
I think also rather than a wad, those sub bases would be of a particular use with these boolits. May want to give them a try with them in the future. If you don't have any Ron and want to give a couple a try just yell and Ill send you a few.

I thought it might make it to the phone book. The other ones, (my lightweights), should be easier on things.

Yes, i was concerned about over penetration, so the milk jug was added. Seems the mushrooming was about perfect, and it didn't penetrate too deep after all. What a wonderful bullet, Art!

what would really be interesting is finding out how many jugs it takes to make a bullet start to expand and how many before max expansion takes place. I think that would require one of those $75,000 - $100,000 slow motion cameras though.

If you could, how far did that conical expand to? It looks like the top of that is over an inch wide. Think of the hole that puts in a game animal. I shoot a similar bullet but with Triple Seven 2f powder. Great test. And thanks Flounder. That was one I wanted to see.
