Shot some of the Hevi 13 7's yesterday in my Reminton 870 20 ga youth using a TruGlo GSX choke. After shooting, I picked up the wad and noticed it had holes all in it. Also, the base of the wad or I guess it's called the cup, looked kinda shredded. All the petals of the wad were full of holes. I'm wondering what would cause this. I'm thinking that maybe the forcing cone in my barrel is a little ruff or maybe this is occuring as it goes through the ported choke tube. Any ideas? I saved one of the wads and will try and post a pic tonight.

Went and picked up a RSF 0.572 lead only choke from WalMart to do some testing. Yea, I know it says lead only but I know plenty of people who have been shooting Hevi shot in them for a while. Anyway, first shot at 30 yards yielded 246 pellets in a 10 at 40 yards. Next shot was at 40 and I got 140. With the TruGlo GSX I got 113 in a 10 at 40 on a clean barrel and 96 on a dirty barrel. One thing that was a great surprise was the wadding this time around. The pictures below speak for themselves. After this, I would say it was the ports in the GSX causing the problem. The the 2 good wads were fired in the RSF choke.

maybe a dirty bore....choke design and constriction will definitely cause the wad damage you have. :)
Clean it real good. :agreed:
how were the patterns?
Haven't done any counting yet, but the patterns were nice and even @ 40 yards. Outshot lead shot in my 12 gage 3" gun. The barrel was cleaned and polished prior to shooting. First shot on a clean barrel went about 7 inches left shooting out of a gun vise. Looked at the wadding out of that shell and one of the petals was completely torn off. Next shot on a foulded barrel was dead on with a nice even pattern, but the wadding had holes all in it and was pretty messed up. That choke is smooth as glass on the inside. You can see some rings on the forcing cone that look to be left there when the barrel was machined. I tried polishing it with scotch brite pad and fine still wool. Wish I had one of those flex hones for polishing the forcing cone.
Holes right through it, or indentations in the plastic from the pressure of loading?
CB
Holes all the way through it.
My SSX is heck on wads as well..
How small was the choke. Did it have stops in it. Did it have the lines in it.
That makes sense. That wad feels thin a paper. I think the choke constriction is 0.565 to 0.570. I looked at the forcing cone with a light last night and it really ain't that rough.

It's the wad.
That's a CSD wad, and they look like that with most heavy loads, in my experience. They just don't hold up very well to the rigors of heavy turkey loads, unless you keep the pressure really low. It they switched to a tougher wad (and there are such wads available) you wouldn't see any of that.
That has not a thing to do with the wad or the barrel It is the choke that did that to the wad. We pick up wads all the time. We have thousands of them on the test range. The choke is to aggressive.
I shot a Win 3.5-2 1/4-#5 through a Rem ventilator choke this afternoon and noticed that their wad looked strikingly similar to the one you posted. Everything was clean in my gun.
I have had the same results as . I started off loading hs in the csd 20 ga wads. The petals had holes in them and the rim on the powder cup was turned up, where the pressure blew by. Went to a different wad, same gun and choke, dirty barrel. No holes, no upturned powder rim.
:newmascot:
If the wad is soft that will take one choke if you run a hard wad you want a choke that has alot of tapper or big stops. I have to deal with this every day. That is part of the Custom choke deal. We have a diffrent choke for each gun with a diffrent lay out on the inside for each gun and shell. That wad is soft but I will pic some up of the rang and post pic of them. We stop them at 20 to 25 yards from the gun and they not have holes in them.
We have a diffrent choke for each shell on the market. We DO NOT PORT our chokes. We do all our work with tapers positive and negative. That is the deal with the ports. I would look at that wad and say take out some of the ports or back off on the stops to fix that.
Thought I would add a picture of the choke tube for those who may not know what it looks like. Cheap choke from Wal-Mart. No wad stoppers present. Also, the first shot I made on a clean barrel, one of the petals was ripped clean off of the Wad.
YEP,them chokes u'll tear'um up quite abitt! Watch that those 7's don't blow thru the ports! :anim_25:
Is that choke seating on the muzzle of your brl.? picture looks like it is to me!! :o
Yes it is tightening down flush with the muzzle. Is it not supposed to be?

No it should not touch the muzzle,the back skirt of the choke should seat inside the brl.
How did that setup pattern? I am going to try that exact setup.
I only had 113 pellets in a 10" circle at 40 yards. Next shot on a dirty barrel was around 95. Going to try a Rem Super Full next and see what happens. By the way, I killed 3 turkeys with this setup last year. One of them was 46 steps.

Added an update to the top of the post.
I have noticed that the larger the ports the more damage. TG GSX,Star-Dot have large ports and tend to do more damage IME. I have a pure gold also and the ports are a lot smaller and the damage is not as severe. The slotted chokes like the JH and IC don't seem to do much damage they just groove the wad some.
