The photo shows Ed' 347 grain hollow point after being captured. The powder charge is 50 grain Blackhorn. HERE links the event.



Ed-great looking bullets and great downrange performance. I'm thinking the 80 grains of BH rather than the 50 grains might be a deciding factor..........

Obviously, Ed' bullet worked fine using 50 grain Blackhorn. Eighty grain is not the deciding factor here.
 
Dave/Ron, again I'm no ballistician, but food for thought. Could it be the tip of the bullet? Mine are more rounded or with a wider metaplat where when it hit's the wider surface enables the bullet to mushroom more? Dave, maybe it's time for a new design?? I'll be glad to test them with my .451 Whites! :D

This stuff could keep you up at Night??? :bang: :D
 
I find these results and processes REALLY interesting! In a previous post I may have appeared to be scrutinizing the process but understand the necessity for repeatable results. Bullet performance has always been my goal when designing and manufacturing muzzleloading bullets. We have "tinkered" with several medias from ballistic media, bottled water, sand and phone books to realize what works and what doesn't. I find myself learning a lot from Ron's work. While it does deviate some from our results, it drives me to wonder if it's velocity or media driven. Part of me wants to say, that the water slows that bullet down substantially causing it to mushroom less when it finally hits some "meaningful" media. Another part of me wants to think that maybe the reduced load may be driving the non-noteworthy mushroom (performance) down range. I'd be more than happy to donate a couple boxes toward more testing. Email me an address and I'll get them on the way. ([email protected])

I know nothing of the bullet casting stuff but in looking at the bullet that been drilled, have you considered casting that the bullet with a slightly larger mataplat and casting them with a larger hollow point. Maybe a touch deeper and wider. Then swaging the bullet to the shape we see here to help close the hollow point up a hair. You should end up with a fair size cavity under the bullets slightly smaller nose. Maybe too much work but I would think that by having a slightly larger cavity inside the bullet proper could help get expansion at slower velocities. Just a thought....maybe too much work.
 
The whole idea of the 50 grain charge was to see if bullet performed at a distance or the lowest velocity it would expand , doesn't mean it won't work at say 100 to 150 yds. with 80 grains

347 grain bullet is going to be traveling faster than a 420 grain with a 50 grain powder charge.

Velocity into water is the deciding factor. Put enough powder behind the bullets to get them traveling the same speed, or you are just comparing apples to oranges. Chronograph will tell the story.
 
Valid point Busta, I never thought about it that way. Great insight.

Shoot them both with 80 grains. I'll take the full weight leaded version for elk and other big game, everytime!

Solid Lead penetrates, stays together, and kills!

Shoot 'em with 80 grains, and post the results.
I agree 100%. I never shot a elk, but deer just drop upon impact! Only a few exceptions an they don't go out of sight even with a marginal hit.

........ Put enough powder behind the bullets to get them traveling the same speed, or you are just comparing apples to oranges......

If the bullets are traveling the same speed, the 405g bullet will have 17% more energy than the 347g bullet. Seems you may be comparing apples to oranges?
 
I think we been down this road forty times , which your tests weren't designed to show 100 yd or 25 yard velocity. It was to show how or at what velocity and distance it still worked. Thus the reason to use 50 grains, which is to show the distance it would stop expanding. I don't know that velocity or what 80 grains would be in velocity for that bullet, but i have no problem understanding what he was trying to show. I do know what might work at 100 won't at 200. So maybe you guys need to do your ballistics and see
 
Sometimes, it doesn't always go as planned...:D
............


When the paraphernalia is being assembled so a bullet might be captured, care is taken to ensure the bullet will be found when all is done. It is highly disappointing when the bullet isn't found. Mostly the bullet is caught, and the shooter is pleased. There is no plan other than that. Thus, you see, this particular result went as planned, as most do. So...........i confess i don't understand your post.
 
From looking at this, it seems the dif between pass and fail may have only been the diameter of the hollow point. I'm only looking at #40, 41, &42. Is that correct? Is this what you are showing us in the vid and pics?

My apologies, I put this in the wrong post, sorry, I can't edit it out. I had multiple tabs going on the laptop.
