Polaris754 - I have read the posts made here and there is some good advise. I think you have one of those tight bore Omega rifles. Not all of them are tight bore, but you might be one of the lucky ones. Because of this, the Triple Seven fouling is closing up the diameter of the bore on you. That is what is making loading hard. There are a couple things you can do.

First thing I would do is get rid of the bore butter. That might be gathering fouling actually when you shoot, only increasing the problem. I would boil the barrel clean and get that bore butter out of it. If you want to protect he barrel and make is smooth, get some Montana Xtreme Bore Treatment. I have been using the product in some of my rifles and must admit.. I can not swear it is making the fouling not stick to the bore, but these rifles are sure easy to clean. The bore treatment will protect your bore and make it easier to load.

Because of the tight bore, I would also take some JB Bore Paste and give that barrel a good scrubbing. This will help to smooth out any areas that might be grabbing fouling, but besides that I will make the barrel smooth and make loading easier. And it will only remove fouling and residue from the bore. This is not a lapp so it will not remove any metal from the bore.

The main thing.. Triple Seven is a good powder. But no matter what powder you go to, your going to get fouling of some sort. Blackhorn 209 might be a real good powder for you, but it is not always cost effective and I am not so sure I like the idea that I have to use a chemical to clean it. I am an old soap and water man I guess. But you can use the powders like Triple Seven. The key thing is you have to swab better. Swabbing is a PITA and I am the first to admit this. I hate to swab. But when I do, I do a good job.

Sabotloader gave you some great swabbing tips. Work that damp patch in short stroke, actually scrubbing the bore. When you get down near the breech, slow down. Take your time here. Really work the patch well. When you remove it, flip it over and do it again. Then a couple dry patches. You should not need to add bore butter to the barrel. That is only closing it up again. And it is not recommended by T/C I believe in their manual when shooting sabots. The sabot is the slider.

If your concern is hunting, and you think.. I need a fast second shot. Find a projectile that might be that fast second shot. This might be a conical bullet, a powerbelt, or even a different sabot combination. But there is something out there that will work. You have to find it.

Also go to a Harvester Crushed Rib sabot when you shoot. These will help with the tight bore and make your loading less of a effort.

These are something I would try.
