I Need a Better Backstop

[FuzzyGrub]

I think most of my pulverized stuffing will float and would try a water separation method.  Some would end up with the lead, but probably burn off in the first melt down stage.  Not sure what rubber particles would do but suspect some dark arid smoke.  Probably allot more trouble than its worth.

Great tip!  I'll have to give that a whirl

I reclaimed this from my trap using a water separation method.   It takes a pretty good size tub.  Some of the rubber floats some, but most is kind of in a slurry.  At least the lead drops to the bottom and when stirred the rubber goes into suspension. 

It created a lot of black smoke when smelting, and the rubber burning adds to the heat to get the lead melted.  After I could tell the lead was melted I snuffed the rubber fire with the lid.  Had a bunch of rubber charcoal on top and just dumped it off.  I must do outside kind of operation.

I am a long ways from doing any casting, but it does seem to interest me, so maybe in the future.  I haven't even sorted out the NSA slugs in my big bore yet.  These are good tips though that I'm taking notes on for sure, and am thankful for.  At least I got a backstop now to collect lead if I ever do some casting.

To date, my casting is for underwater hunting.

Putting the lid on really helps. The remaining cloth if any, and mulch will act as a reducer, and cleaner, and flux the lead well.

I tested my new indoor rubber mulch backstop today with the .357 Slayer.  Looks like it will work!  The distance from the muzzle to the backstop face was 6 feet exactly.  The nine shot grouping was somewhat tight, but not a single hole.



I took the lid off and carefully dug down to see just how far the 142gr NSA slugs went in with the nine shot string I ran.  The measurements as a dug down were as follows:

• 7.75"
• 8"
• 8.25"
• 8.5
• 5-9 were at 9.25"

The total depth of the rubber mulch is 15" so I had plenty of room to spare plus the 1/4" steel plate in the second tote/bin.



The back of the lid took a good hit.  I should have put some duct tape on the backside to prevent such a chunk being removed.



I did put some heavy-duty duct tape on the backside before reassemble to help out the plastic in the future.



This is what the slugs looked like after retrieving them.



Here is the nine shot string showing the energy applied.



Here is the string without the first stiction shot and only viewing six of the shots, which the gun was built around (6 shots averaging 275 FPE).

Hey, Keith.... first time I have seen a shot string on the Slayer.... If you back the power down a bit can you get an actual bell-curve?.... Without the first (stiction) shot, as you indicate, it is 2 equal shots and then a decline.... While that is a great tune for a big bore, I'm curious if a bell-curve is possible.... Still, 5 shots within a 3.5% ES is nothing to be sneezed at....

Yes it will on a 3600 psi fill.  I tried the max fill today at 3800 just to see.  I posted my first string filled to 3600 psi over on the .357 Slayer thread.  I'm not sure what that first shot was about.  I know the gun has been sitting for a while and was cold plus the extra fill pressure.

[rsterne]

Ahhhhhhh… if you were over the pressure it was tuned for, the first shot would be low, as you experienced.... Makes sense.... Likely NOT a stiction issue, just partial valve lock from the 3800 psi....

It's an awesome gun,  but I just got it, so still getting it sorted out.  I don't know if you found the other thread, but it's very accurate,  that I have figured out already.

FYI, the pellet/slug trap I built works fantastic (reply #76)!  It has stopped all slugs I have shot at it with my Slayer, much of which are only a couple of feet away from it, and typically near 300 FPE or more.  Never once has a slug poked through the back of the mulch and into my backup safety steel plates in the second tote.

I don't have to move the second tote with the steel plates when relocating this outdoors, which makes it much lighter to deal with.  I still do need a dolly to move it though, which is easy to move that way.  I use a hoist chain setup to raise and lower it on the table you see in the picture.  Very easy that way.  One day I'll reclaim the lead from it when dipping low on lead for casting.  I use it for all of my guns.  Works great for me and is a silent trap, which I like.

I've enjoyed the rubber mulch traps for years.However, I got tired of the hours it took to reclaim the lead. Some are lucky I guess. I find that a great deal of the mulch sinks in water. PITA!!!


This is why I switched to real purpose built bullet traps. I simply pour the lead out. Easy, Peasy!
