Okay. Inside would probably be less effective and certainly harder to apply but on the outside we're dragging tape along the bore under pressure. I'd probably be over-worrying about that.

If you are concerned, you can, as I did, cut the petals loose before inserting them in the hull. After about 100 rounds I quit doing it because there was no discernible difference in performance. Not that I did comparative patterning or anything, I just couldn't see any improvement in scores or breaks.

Giving it some thought I realized that the wad separates from the shot somewhere between the choke and the first few inches from the muzzle so there shouldn't be any difference and I detected none. The fact that the wads flew quite far down range is what took me down that rabbit hole in the first place.

I informed the distributor (Precision) of the problem with the stitching not breaking. They were unaware but immediately went to verify. I wrote the manufacturer but have not had a reply.

As has been said, the purpose of the pedals is to deploy upon leaving the muzzle of the gun to allow the shot to be free of the wad. The DR16 has thick walled pedals to take up volume in the shot cavity. Claybusters, in their ¾ ounce wads for 12 and 20, have thin walls because they have a protrusion into the bottom of the shot cavity to take up volume. I believe that the thick walls of DR16 make them stiff so they resist the forces to deploy and therefore do not have the strength to break the stitching.

So, running the risk of being labelled OCD, I have decided to slit the stitching in the DR16 with a utility knife so the wad can function as designed and the pedals will deploy without the restraint of the stitching. I find it quick and easy to do at the bench with a sharp utility knife. When I have used up my supply of DR16s, I’ll check to see if Downrange has fixed the problem and, if not, I will look for a replacement.

Loading a 2 ½ in Cheddite skived hull, DR16 wad, ¾ oz. #9 shot, 16.6 grains of International and using a 6 point crimp in a MEC Sizemaster. Works beautifully.

Some have strongly suggested that it make no difference in the pattern if all the petals don’t separate. Be that as it may, as an engineer-gone-bad, I like things to work as designed.

Don,
Great
Good on Ya!!
As you are now labeled an Engineer-gone-bad I am looking forward to your experimentation data where the petals opening up made a difference.
Thank you Smile
Mike

I fired five shells from each barrel to check my aiming point. The aim point and pattern were satisfactory. At this point, I am going to go silent. This discussion has all of the earmarks of the discussion among pilots as to the best way to land a tail dragger in a crosswind. One side is never able to convince the other of the wisdom of their way of doing it. The real answer is whatever makes you comfortable.

So it is with DR16 stitching.

Peace
Don

You are a wise man !!

Dad always said " Do not play with the pigs in the mud, you get dirty and the pigs like it!"

Enjoy the reloading and shooting

Memorable quotes from my life in industrial science...

“In God we trust. All others must bring data.” – W. Edwards Deming, ."

“It is a capital mistake to theorize before one has data.” Sherlock Holmes,

“The great tragedy of Science — the slaying of a beautiful hypothesis by an ugly fact." Thomas H. Huxley

or, as we liked to say...

"Dontcha hate it when a beautiful theory is ruined by ugly facts?"


Finally,

“If we have data, let’s look at data. If all we have are opinions, let’s go with mine.” – Jim Barksdale

In this case, I believe it goes something like..........an ugly theory has been ruined by beautiful facts.

Can you imagine how many bad loads there would be if wad stitching was actually a factor?

After a long, pleasant talk with NIck, he convinced me that it does not matter that the stitches on the DR16 don't break. It does not effect the pattern.

Oh dear, what is an OCD engineer-gone-bad to do?

Peace
Don

"Oh dear, what is an OCD engineer-gone-bad to do? "

Most of them shoots dozens of patterns and count thousands of holes. Eventually, they collect enough data to write a manual. Wink Laughing

You're probably right, but - if the targets continue to break - that's good enough. Life is short.

Peace
