For the record, I don't care if people like or use Crosman pellets. I used to use them a lot until about summer 2018. I've had tins of Walmart 177 CPHPs that were phenomenal and shot better than some JSB and H&N. I've also used the brown box single die CPLs with great luck. Those were great pellets.
My problem with the Crosman pellets is two-fold. First is the lack of QC. Unless they've improved the 177 Walmart CPHP seem to vary quite a bit in size within the tin. Heck I had to return two out of three tins once because they had 22s mixed in. Brands like JSB, RWS and H&N stay closer sized within a tin. Not always perfect but markedly closer. Thus they typically have less radical flyers. This is why I recommended trying them to Nasty when
he mentioned he had some undersized pellets giving him flyers. Then he went nuts on me. You'd think I bashed his mom or kid.
My second gripe with Crosman isn't because they're dirty per se. BTW I believe the dirt you see on your fingers may be graphite powder. Crosman used to add graphite powder to their pellets. Why, I don't know. My second gripe is that Crosman uses a lot more antimony in their pellets than other brands. This makes them harder than other brands. It helps prevent shipping damage. The problem with hard lead is you either have to use it all the time or not at all.
Barrel seasoning or (fouling in a good way) is very important to accuracy. It can take a hundred sometimes a thousand shots to season a brand new or newly scrubbed and polished barrel. Shooting six hard lead Crosmans can almost undo all that soft lead fouling or seasoning. The hard lead scrapes it right out. If you continually shoot Crosman pellets or more Crosman than soft lead brands the barrel becomes seasoned with hard lead.
Soft lead can't clear the hard lead for obvious reasons. Now the expensive brand soft lead pellets just won't print as good as they should. At least until all the hard lead is literally scrubbed out and the barrel goes through the whole seasoning process again with soft lead. Which depending on the barrel can takes hundreds of expensive pellets. BTW soft lead pellets won't ever excessively foul a barrel. Crosman will. I haven't needed to clean any of my personal gun barrels since switching to soft lead brands. Some of these guns have over 30k shots on them.
Anyway between the inconsistent QC (flyers), the hard lead screwing up my accuracy with other brands and additional maintenance, I've decided not to use Crosman pellets. I can afford better pellets, so I shoot better pellets. I get more consistent accuracy from them and I'm willing to pay for it.
If someone else wants to shoot Crosman pellets and they are happy with the results they get. God bless them. Just don't waste your money using expensive soft lead pellets through a Crosman seasoned barrel because they won't print as good as they could. If you're happy with the Crosman, stay with the Crosman and maybe just clean the barrel every couple thousand rounds to keep them shooting well.

. It’s a 177 cal an has new spring Also have the 22 cal barrel for it. But the majority have great success. With this model. Mine has barrel droop As well
The rifle was new in January. Some where on this forum I have a write up of things I tried. To make it shoot better . It’s on its second new scope 
I’m not sure, I have some things in mind to try. Probably this fall . I’m determined to make it my #2 squirrel gun. The HW90 is #1 But that HW50 is an absolute delight to shoot . Don’t read this last part . It likes thos 7.9 crosmans .
