Rumint says Hodgdon is bringing out a new version of T7 called Firestar.  It is supposed to deal with the crud ring.  Anyone know anything about it?  All I can find is the patent  request and that it will be available in pellet form.

Impossible to get rid of the crud ring. Even real BP leaves one.

Blackhorn 209 does not leave a crud ring.  Pyrodex does not leave a crud ring.  Just a tapered level of fouling from bullet to bore.

Not true. Pyro does. Not as bad as T7, but it's still there. Even when using real BP if you get a patch stuck cleaning it will be in the exact spot the T7 gets a crud ring.

BH 209 doesn't get one, because it's a smokeless powder disguised as a BP sub.

With the exception of Black Horn 209, all  the black powder substitutes, and black powder itself, are capable of forming crud rings.   Crud rings happen when the fouling (potassium carbonate) gets hot enough to melt and fuse to the bore.   Triple Seven is a hot burning powder, that's the primary reason  crud rings are prevalent with that powder.   

One can  lessen the Triple Seven crud ring by:

1.  Using a Triple Seven primer.

2.  Reducing the powder charge.

3.  Allowing the barrel to  cool between shots.

A baked on crud of fouling where the propellant meets the projectile. Mostly infamous when using 209 primers.

Thanks for Video clip.
I have never had that happen in 25 years of shooting Muzzle loaders.
Again I shoot a lot of T7.
But I don't shoot inlines and my normal loads are 60gr. & 70gr. in a 50Cal.

Guys I have a question here. I've been burning a bunch of double f lately. I shoot an under hammer in 45 cal. 85 grains ,round ball. Last week my temps were around 45 to almost 50. No sign of a crud ring. I swab after every shot .  I normally drop a slight wet patch and follow with a dry patch. Easy down easy up. There is a good amount of alcohol in this stuff so it doesn't freeze.  This week we're down to maybe 35 high. All of a sudden I've got this ring you guys mentioned. Same everything else wise. My question here is ,do you think temperature has any bearing here.This is the only difference I can put my finger on.I shoot a lot , 1 lb for a week or 10 days. All double f goex. This goex was one of my better  thoughts years ago.

I took the night to think of this.. but.. What patch lube are you using? Does it have any beeswax in it? I was thinking thats its possible that the lube could be hardening in the bore while you are reloading.\

If you swab between shots, that would remove a lot thats left in the bore, but with the cold, maybe its possible any wax from the lube is gumming up in the cold?

Hello Jon, I don't use any lube to say . I 've used Dutch's system for many years.  Funny thing here is I don't have this problem with any of the snailed guns. Thompson , Cva, so on. I got to thinking , my under hammer is much like your inlines, where as the snails are not. Reason I shoot a lot is my son inlaw  owns a sports shop . Oct. and Nov. are hot guns sales . I help out with black side of it. I love to shoot ,but this gets to be a pita.Don't seem to make any difference what I use for smoke. I guess it's one of those things that we'll have to live with. If someone could say ,use this or that, I'd be interested in buying.Like I mentioned  before I normally use Dutches system but I have tried olive oil , cresco, spit, moose milk  and maybe some more. All ,nonpetrolium .The cold seems to be the only thing coming to my mind.

could be. The dry patch method does require swabbing between each shot which is why i dumped that method in a hurry. Are you using ballistol or the napa cutting oil?

I been showing the guys that own the rifles whats going on. I would not trust my self  to ram a quick second shot  and feel safe about it. You know what happens if the ball or bullet would not be down tight.The ones I'm talking about here are the guns I've bore sighted and got on paper good for their new owners. Some are patched ball, some sabots, some slugs. It is what ever they wanted.Most all the guys envolved were right with me.Can't say what they're using for the patch. On the oil thing , I can't remember,I bought a gallon maybe 35 years ago. I still have better than half left. I just this season started with my under hammer,that's why I never run into this before. It's funny someone has not had a serious problem already.

the crud ring thing can vary from gun to gun I have found, my dads cva magbolt has no problem with t7 or pyr pellets causing a crud ring, I went to swab his barrel between shots and there didn't seem to be enough there to stop from loading again, I was jelous.

Thats because the mag bolt loses so much primer gasses, it doesnt create the crud ring no where near as bad. Seal up the primer blow by and the crud ring appears. Winchester 777, CCI Inline mzl primers help reduce it. Just a lot more expensive for those primers.
