IT"S DANGEROUS and could possibly bulge or blow up the barrel.

Right on the nose builder. :woot:

You don't get a crud ring at the bottom of the bore with a #11 cap due to them producing low heat.

This is what his bullet is getting caught up on.

Are you saying that the 209 primer my nephew uses creates a significantly worse crud ring than my #11 magnum primers? I never would have thought that. I was going to try loose powder in his rifle the next time at the range, thinking that maybe the pellets were dirtier. Should be interesting to see if that makes a difference. It may be he is just going to have to swab between every shot.

I know for sure he can get a proper seat for the PB if he swabs every time. But I have always been told by traditional black powder folks who shoot at the range in competition that they always like to shoot on a fouled barrel and I always told him that. Maybe that's the difference between modern and traditional. Or maybe Powerbelts and a patched roundball.

That's right Bruce, but you can still get a crud ring even using caps. It is absolutely best to swab between shots with an alcohol or Windex patch then a dry patch or two.

The severity of it, even the existence of it, can vary from one rifle to the next even among rifles of the same make and model.

Worst invention I ever came up with. ;)

Yes the hotter 209 primer creates a far worse crud ring , than a #11 cap will.you will know when you hit the crud ring during swabbing between shots.if it's real hard work it back and forth with the moist patch and it will dissolve.

So YOU'RE the one that developed the crud ring! Where do you live? :s2::s2:

I am hoping he can at least get at least 1 follow-up shot before swabbing. Swabbing between shots is no big deal on the range, but it would be nice to not have to do it in the woods during deer season in case he wounds a deer and needs another "quick" killing shot.

Thanks everyone for an education. It's a good day when I can learn something!

Try getting some primers that were made for T7. They are a little cooler

I cant believe that after just one shot your Nephew has that hard of a time pushing the Sabot onto the Pellets for the next shot, is He pushing down Hard Enough on the Sabot for the second shot? Usually Powerbelts Load Easy. I have owned at least 7 different CVA's and have shot Pyrodox out of all of them and never experienced this with any of them, even after going 3-4 shots befor swabing.
Have Him try a Lightly coated Windex Patch between shots and see if this helps. I would Never Shoot a Charge that was'nt seated Properly, especially as far off as you say it is.
I have No clue what could be wrong, just try the Windex Patch Swab between shots and see if that helps.

I have a hard time believing it myself. I also tried it myself because I thought he wasn't pushing hard enough. But it is impossible to completely push down that second shot. That's why I asked here, because I have never seen anything like it. Heck, I can get at least 4 shots with Powerbelts out of my rifle before swabbing; more if I wanted to push a little harder.

Its hard to push through the crud ring of T7 even with a powerbelt. IMR White Hots are a LITTLE softer fouling wise but even then you can end up with a nut down each pant leg at the end of the day from pushing.

I thought Your Nephew used Regular Pyrodox Pellets and You said (You) used the T7. Well if He uses T7 then I can see some Crud from the T7 but that much. Have Him try the Regular Pyrodox Pellets, they work just fine, see if that makes a difference.
