RE: loose powder or pellets
I won't buy pellets again. They shot ok. That wasn't the issue. I was doing alot of bullet test yesterday with my older inline. I cut my groups consistently by 50% by shooting 95gr of pyrodex instead of 2 50gr pellets. Also much better groups than 100gr of pyrodex. For 100 yard shots, you can really dial your gun in with pryodex which is hard to do with pellets.
They are so much more expensive also. And it really isn't that big of a deal to measure out your powder.
