Yes they do but I couldn’t link it due to forum rules. I just wanted you to see what the bags look like. I ordered directly from jacks. Apologies, I should have mentioned that.
Looks like you have autos. I know autos like less feeding so I’m not sure on the frequency of feeding for Jack’s on autos. It is gentle so may be ok to go full on with it. @Nicky is actually running jacks this round so maybe follow along to see how he does with feeding.
