I'll be in the area over the 4th of July. If you haven't found someone with the nuts to shoot it let me know.

@copaup - Nope, I didn't take any photos of the muzzle flash - believe me though, it was there! It was visible (knowing that I was focusing on the front sight) against the background (wooden bench, grass, gelatin block) that was in full sunshine.
@XDKingslayer - Thank you for the offer. There are two other people looking to participate in the testing right now... I will let everyone know once I have heard back from them (or not).
Hmmm. The idea of 'walking up' the load is a great idea. But this test is being paid for by someone else, and they have two factory loads that they would like to see tested in gelatin. So, I'm on a budget for time in order to do this test... but a load development may be the only solution in the future. Thank you for the advice.
Basically ... there are two things that can usually be said for my website - it's run on a shoestring budget (the necessity of buying gelatin powder and new refrigerators for when the heat load breaks them) and the time that I can spend on it is usually short in supply.

But we appreciate it.
Yeah, JE223, but you're doing all of us a great service, and we appreciate it.
Anyone who can, chip in and donate - it's to your own benefit. "Sponsoring" a test is great, but kicking in a few bucks also really helps the man keep going with this great research.
Oh, and I heard from the owner of the .45-70 derringer after he shot it: took a week for his hand to stop hurting.

Update:
Mooseman has kindly volunteered to shoot the .45-70 Derringer. We are currently working out where the test will take place, but it is tentatively planned for two weekends from now.
The first shot should be the 300gr Cor-Bon DPX bullet against bare gelatin. Depending on how that goes, expect to see a bare shot against Federal 300gr Powershok. Other barriers will be included in the test, depending on the amount of damage done to the block/number of blocks available to test that day.

I don't really know what Mr. J.K.'s interests in this are, but if he is seeking out performance from these various rifle calibers, he may actually do better to select rifle squib loads using typical handgun powders. In a rifle, slow-burning powders will get you better velocities because they will maintain higher pressures further down the barrel, but in these short derringer barrels, I wouldn't be surprised if they never even come close to reaching peak pressure. Faster pistol powders may be able to generate more pressure and more velocity in this situation.
To save money you could do the load experimentation with just a chrono and save the gelatin for the best performers.
Just a thought.

Hey, I just tests what they sends
Those are some interesting ideas, but I am currently not setup for load development. I think that the customer (J.K.)has a leaning towards Derringers. Can't say I blame him either - the ones of his that I shot were very precise and of course reliable. The recoil of the bigger cartridges approaches my limit though - not a big fan of anything bigger than .223REM in a Derringer right now.

Those results aren't great, but why are they pitifull? A tumbling full-length .223 projectile tearing a 12" wound channel is nothing to sniff at. Ft lbs of energy in itself is a meaningless stat. in terms of handgun wound ballistics. Only the depth and size of the wound channel factor in to the mechanisim of wounding for handguns.
Rifles have the velocity to damage tissue with the temporary wound channel so they have injury potential beyond the permanent cavity.
