That is an old hammer/striker model rifle. Not that it makes them bad. Just older technology. I shoot a number of Hammer/striker model inline rifles and love them. And this might not agree with a lot of people what I am about to post, and that's fine. All opinions are welcome. But here goes...
First thing is get that bore butter out of that rifle! That stuff is a good conical lube but other then that it smells nice. It just does not work good in your rifle. Remember your rifle is made of top grade steel. Also there are products out there that can do a much better job of protection for your rifle and not something that is going to fill the lands and grooves on an already "in trouble" rifle bore. An easy way to remove the bore butter is boil the barrel. Take the barrel out of the stock. Boil water in a coffee pot, tea kettle, what every you can pour from. Take the barrel outside. Have some leather gloves with you. A ramrod with a good brass brush, and some dish soap. Put a squirt of dish soap down the bore. Now fill it with boiling water. Let that soap and water sit a couple minutes to "cool down." Now with your gloves on, pour the water and soap out of the barrel You will see the bore butter floating out. Add a little more water. And with your gloves on! Use that bore brush up and down in the bore to scrub out all that junk! Fill the barrel with water again. Let it sit. Add more water. Let it sit a few minutes to see if more wax is coming out of the barrel. Bore butter is wax mostly. Wax is for furniture and cars to make them shine. Not to protect them from rusting. Now dump the water out of the bore again.
Start running dry patches on a jag up and down the bore. If you have some brake cleaner around. Remember barrel so out of the stock. Give a good blast of it down the bore of that rifle. Now start with the patches again. After and if the bore comes clean apply a quality gun oil, like you'd use on your modern rifles, and swab the bore good. That hot barrel will pull that oil into the bore and pours of the metal in there.
Buy yourself a product called JB Bore Paste. Have a good supply of patches made up. Apply that Bore paste to the patch and work that down and up in the bore of that rifle for 25 strokes. A stroke is down and up. Then throw that out and do the same thing again with another patch for 25 strokes. I like to give a bad barrel 100 strokes. Now take that barrel outside and fill it with boiling water. Don't forget your gloves. Dump that and do it again. Now take the barrel somewhat and with isopropyl alcohol or something like Birchwood Casey Bore Scrubber, swab that bore until the patches come out as clean as they will. The bore paste will pull the hard to get rust out of the pours and grooves. It will also smooth out ruff spots. The washing of the bore and the Bore Scrubber will clean out the bore paste. After the barrel is clean, again.. a good gun oil on a patch and swab that bore. You want to use a good gun oil. Birchwood Casey Barricade, Montana Extreme Gun Oil, Barastol, Breakfree CLP ... all very good gun oils. And to get them out before you shoot, all you need do is swab with an isopropyl alcohol patch or Bore Scrubber. Then a dry patch or two and your good to load and shoot.
