Blown out patches

[D Sanders]

I have a .54 cal. ball shooter. I shoot a .535 ball and a .018 pillow ticking patch over 90 grains of "double f" black powder. I have had great performance with this load for years out of the same rifle. Just recently I purchaced a new can of powder. (the same manufacurer and granualation) The patches were never blown, but now they are. I have changed nothing in the load but a new can of powder. Could this new can of powder be burning hotter than the previous can? What can I do to prevent patch blow out with this new can of powder?

I use goex. This is the same powder I have always used.

There are a couple of easy things to check first, namely ball size and patch thickness. Then possible bore roughness. Try dropping back 5 grains to see if the powder you are using now is a little hotter. If all else fails, make sure you are using your old ticking or whatever and it is the same. I got some of thet new improved GWANGZHOU GOLD, SPECIAL HEAVEN 100% CHINA BEST cotton ticking and it just isn't the same, even tastes different.Wonky

Load one and pull it unfired, hold the patch up the light and see if the patch is torn. If your bore is rough no powder change will help.
