Well, yesterday I decided to test out my Genesis for the first time. We used my Nikon laser range finder to set-up 100 yards away from the target. I started out using 120 grains of BH209 and just couldn't seem to get it to group well. I went down to 100 grains and it shot a whole lot better. I was testing 3 different bullet/sabot combos. 300 grain Hornaday XTP with Harvester green crush rib sabot, 275 grain Remington PT with supplied sabot, and 290 grain Barnes Spit-FireT-EZ with supplied sabot. Out of those three, the Barnes T-EZ's grouped the best so I think I'll be using them. We brought a couple melons with us and after I dialed in the load I shot one of them. It exploded in a very impressive fashion!

Afterward I went to clean the Genesis. I already had some Hopps #9 but I decided to try using Remington Express Clean Solvent Spray first. I sprayed some on a few patches and punched the bore several times. It's cleaned everything up just fine and I never had to use the stinky Hopps. So for those of you using BH209, the Remington solvent works also. I'm pretty sure it's the same thing as Traditions solvent.The breech plug was a little more difficult to clean but only because of the fouling from the primers. The end that had build-up from the BH209 cleaned right off with a rag and q-tips after a short soak in Remington Express Clean Parts Bath.

I used Remington Premier STS 209 Primers for all of the shooting and they fired off perfectly every time. I fired 20 shots without cleaning the bore and every bullet/sabot loaded just as easily as the first one did. The breech block did get a little difficult to open after 5 or so shots, but that was because of the primer fouling. I quick wipe with a rag remedied that.

All and all I was very impressed with this rifle and with BH209. I have no complaints other than my sore shoulder. But I'm very happy to be sore.

I was shooting BlackHorn 209 out of mine when I first got it, shooting 250 grain Shockwaves and I believe it was 90 grain of Black Horn 209 and the accuracy (for open sights) was outstanding. I also discovered that after five or six shots, I took an alcohol patch and wiped the came off and that made everthing work fine.

Are you getting blowback on the scope from your Genesis? Others said they got blowback, but I have shot mine about five times and never really noticed it. Maybe I am so used to the other open breech rifles I shoot, this one seems like a walk in the park.

There's a little bit of blowback on the scope, but nothing to worry about. I just wipe the scope right above the breech with a rag every couple of shots.

You might want to try backing down a little more on your charge and see how it shoots with 90 or even 80 grs. Who knows, it might even be better.
As for the blowback issue, I put a couple wraps of electrical tape on my scope behind the back ring. The fouling wipes of it easily and in a pinch I can use the tape on my muzzle if it rains.
I haven't shot it since Cayugad told me to wrap teflon tape on the breach plug with a little overhang at the start to help seal the breach better. We'll see how that works.

I'm pretty satisfied with the way it shoots with 100 grains. I still want to have the velocity and punch at 100 yards. And from what I have read, 777 and Pyrodex have more power by volume.
