Blackpowder Burn:
Dave, take a plastic hull, load 60 grains of FFg, then a Claybuster 1138-12 wad, then 1-1/8 ounce of shot.  Crimp and shoot!

You'll get some of the plastic from the wad adhere to the barrel, but a short Moose Milk spray down and soak, then it will push right out with a patch.


 :)  Well Dang   ;)

In all honesty, I find the "Snake Skin" to be a curiosity.  At a couple of points during a Match, I look down the tubes and wonder.  The tubes look like a Sewer Pipe.  Makes one wonder if they will ever clean.

Yep.  The tubes will certainly clean.  Amazing.  At some point the week after a match I remember to clean guns.  I squirt a fair amount of PAM down the barrels an let 'em sit for a couple of minutes then shove a brush, also PAM'd down the bore and PRESTO - CHANGEO .... clean tubes. 

Incidentally - I also have and use some aerosol cans of Windshield Cleaner from the local Windshield repair shop.  At stuff works a treat too.  Healthy squirt down the bores, out it comes.  Then, there is the old standby.  Warm/Hot Water.  Same same result.  No sweaty da. 

Plastic wads give me the "Over-Powder" the "Cushion" and the "Shot Cup" all in one.  Keeps loading All Brass Hulls really really simple and fast.


Stay Safe

I have no idea how to do a roll crimp on a paper/plastic shell. Anywhere I can go to learn about this? I don't do well with internet searches. LOL

Roll crimps or Hartin crimps are a "nice to know" and not necessary to make sound and fury. Lots of info here on cascity to satisfy your curiosity through the search function. Roll crimps require a roll crimp head, the best is from "precision". The Hartin crimp can be done on a regular press without adjustments. Both are useful if you have 2.5 inch chambers. Over shot cards can be punched from a milk carton with a 5/8" hollow punch.

You might have to experiment, but any Remington hull seems to shuck out the easiest for me. You might also try roll crimping or the Hartin crimp?

Sir, can you explain or put a link to what you refer to as a 'Hartin Crimp'?  The only thing I can find is a Harting Crimp tool.  But it does not look like something that could be used on shotgun shells. ???  I can roll crimp but have never heard of Hartin Crimps.

Here is a quote from a post of mine back in 2008;

"If you have 2 3/4" chambers, star crimps with paper, or plastic work great.  DD has one of your options, that is to get shorter wads.

If you want to try shorter, 2 1/2" cases, but not bother with roll crimp tools, etc., try  the JAM ROLL. Apparently an earlier inventor of this concept was named Hartin, and it can be called the "Hartin crimp".

-Trim cases
-load your favorite recipe.  Adjust the load to leave about 3/8" (Or a bit less) of clearance from the load to the lip of the case
-top the load with an over shot card.  No O/S wads?  For 20 ga., bash some out of a wax paper milk carton with a 5/8" punch.
-Run the loaded case through your shotshell press's crimp start and crimp stations.  I've tested this crimp on a 12 ga. MEC Grabber, and a 16 ga. MEC 600Jr."

From "16ga.com", a thread with visuals (12 Dec15, on page two)


The result is that the folds of the case mouth are turned in on the O/S wad, which is still visible as a star shape.  A bonus is that the plastic doesn't get heat hardened and the case can be re loaded many more times.
