Just a couple thoughts for you to take or leave:
1.) clean the gun thoroughly before shooting the first time (dawn dish soap and HOT water)
2.) oil the outside of the barrel/rustables after cleaning
3.) fire off a cap only before shooting a load at the range to purge any oil products that might have seeped into action or that are in the bottom of the breech
4.) plan long bench sessions. (I shot for about 2 hours last night and got 6 shots on target...)
5.) pull your breechplug and clean the barrel well each shot (only for bench shooting for groups/zeroing) [I've tried without doing this and groups always suffer in my experience]
6.) make sure you clean the gun as soon as possible after shooting (dawn dish soap and HOT water is my solution)
7.) clean off the cup of the breechplug and make sure once done that there is nothing obstructing the flash hole
8.) Once you've cleaned the gun, put it near a heat source for an hour to remove water if one is available
9.) Use bore butter on patch and put a good coat on rifling (some will disagree, but keeps mine like new)
[You can use oil when storing, but if you do be sure it's all cleaned out before loading]
10.) oil exterior once all dryed up
Have fun with it, just don't be in too much of a hurry.
Most of these are in the user's manual also, but figured I'd let you know ahead of time.
One final thought; create a process/mental check list and do everything step by step the first few times. It's easy to dry-ball (forget powder) if you are going fast. It can be a bit of a pain, although not as bad with an inline vs. a traditional. Some people have double charged too from too much speed. Once you have the sequence down, it won't be as critical.
