I also noticed it bit my tongue a lot more than usual, which is probably the lack of filter right?
it's because it's so small- small pipes aren't good for beginners because they burn so hot. And one that's too big, it's hard to keep lit at first. But it's entirely possible to work with what you've got.
(keep in mind- always smoke a new pipe slowly during the break-in period. It's easy to damage, and don't smoke outdoors with a new one, it can burn too hot and damage it also)
After awhile of breaking it in- you'll notice a charred residue. This is good. It's called a cake, and it means your pipe is ready for anything.
To pack it: there's several different methods, but this one works fine for beginners: trickle the tobacco in until it is overfull, then pack it down about halfway (do you have a pipe tool?). Fill it again, press down to 3/4. Then overfill, and press the tobacco down firmly. If it feels a little springy, then you're good. Draw air through the pipe, it should feel like you're sipping a drink through a straw. Start over if it doesn't, it will save you relights.
To light: use a match, or butane lighter. Fluid lighters work, but they can make your smoke nasty (probably won't notice as a beginner.) Fluid is also the only way to do it if it's windy. Keep the pipe in your mouth, and slowly move the flame around in a circle while puffing on the pipe, until the light catches. Now, this is just the "charring light." Tamp it down (use your pipe tool, not your finger), then light again.
Now smoke. Don't smoke too fast, that'll contribute to pipe tongue. The perfect pace is where the flame is always on the verge of going out.
Don't fret if you have to relight, you usually have to a couple of times.
