i just got back from sighting in my tc omega .50 with 340gr dead center bullets....i switched to remington kleenbore primers and american pioneer fffg powder....i am shooting 100gr of powder....ok heres the good news...it shot 15/16" from a lead sled...heres the bad news

how are the kleenbore primers clean? i don;t remember but i don;t think my breechplug was that BLACK after using winchester primers last year...

second..i love the fffg APP with 100gr...but it almost sounds gritty when i am loading the next shot like theres unburnt powder? and they advertise tons of shots with no felt resistance in loading..by my fourth shot of no swabbing it was pretty hard to push it down the bore....can anyone help me? good news though the load shoots great!

The only thing I can think of, is that`s alot of FFFG. Maybe back off to 90 and see what happens. Maybe even 80 gr. Jack.

870 read my earlier post of what I thought of APP powder.
http://www.graybeardoutdoors.com/phpbb2/viewtopic.php?t=73886
As far as the Clean- Bore primers being cleaner, I didnt notice that much difference between these and Winchester either. I heard that Remington designed these to minimize the notorious crud ring" the 777 shooters speak of so much. I have never shot 777 so I dont know.
As for the gritty condition you speak of, ok lets face it, just about all sabots are hard to push down a tight bore besides the power belt type. I know this for sure, I used to shoot black and it was very hard to push the second shot let alone the forth. I also shot a lot of Pyrodex and it was very hard to push the third shot. The APP was by far the easiest foe me. And the bullet youre shooting is a big boy (340 grain) the heavier the bullet the more resistance you will have.
APP says that grit is a natural lube left behind from the burning process to make the next shot easier to load. Hey the way I look at it if you and I are getting these good group who cares about the grit. Grit-R-Done, Hope this helps.

well i just got done cleaning and my god was that easy!! and i thought 777 was easy.....i only took about 3 wet patches on a patchworm.. www.patchworm.com and then followed with about 5 dry ones...so easy!

i never brushed at all...but i did notice on the mirror inside barrel...some spots about a 1/3 of the way down the barrel from the breech....i hope they are not pitting..i can't imagine they are because pitting would not be so uniform...it's only on the upper or raised rifing..not in the lower rifing grooves...it is at the same distance down the barrel as the rest of it..theres not much...but it's definately there...i have only ever shot 777 out of this omega before i tried app tonight and i clean meticulously.....my dad thought maybe it was plastic from the sabots?? how do i tell if it's pitting shy of a borescope?

why is 100gr of fffg to much? i always shot 100gr of 777

and i use the big boys 340gr because they say on the package they are most accurate in a 1:28" trist barrel...and at the accuracy i am getting i have to believe em...but i am willing to tweak and make changes....i don't know how to measure powder...i either use 777 pellets or app premeasured loads

100 grains of 3f is a lot because 3f burns faster than 2f. Technically 2f is for rifles and 3f works better for pistols. Pistols have shorter barrels so they need a faster burning powder (3f). But 3f APP works fine in rifles because it much coarser than 3f black powder. You will get higher pressures with 100 grain of 3f than 100 grain of 2f in a rifle. But 100 grain of 3f APP is still under the 150 grain max loads my Knight rifle was made to handle.
I agree the dead centers are very good bullets and I'm with you on the heavier the better theory. As long as they shoot good you'll be good to go. Those pits in your barrel may just be plastic fouling like your father mentioned. Get yourself some good plastic solvent most blackpowder solvents have plastic removers in them, also Hoppes benchrest works pretty good if have any of this. Put some on a patch and bronze brush it a few strokes. If it don't come out it's pits.

i will try the brush thing...but in all actuality should a 3 yr old muzzleloader thats only had 777 pellets shot out of it and cleaned thouroughly after every session or shot during hunting..be pitted?

Yes, I was comparing FFFG to FFG. I only use FFG in my .50`s, FFFG in the .32 I use real Black, but would liketo try the APP in an Inline such as my NEF Sidekick. Jack.

I don't know if it SHOULD be pitted but it's very possible. Steel corrodes very easily for a number of different reasons. Have you ever hunted in the rain? If so, maybe some rain got in there and layed on the steel for a little bit it don't take long to start the corrosion process. barrels can get wet from condensation by moving them from a warm vehicle or house to the cold outdoors. Maybe it's very humid where you live that will cause moister. Just giving you some possibilities that could cause pits if thats what you have.
Don't forget Black powder and BP substitutes are CORROSIVE. Maybe not all of them I don't know but yes 777 is. 777 is far less corrosive than blak powder but never the less it's still is.
870, your shooting great groups man, don't let a few pits worry you to much. Just keep taking good care of it you'll be fine (if they are pits).

well things like that make me nervous..i am in the process of about to brush it out really good with some solvent..will let ya know what happens

i just finished scrubbing the bore with a nylon brush and some hoppes no 9....it's still there...but i am not sure if they are pits or not...maybe i need to get the bore hot to loosen the plastic fouling if thats what it is? right now i have cva foaming bore cleaner in there i will see how that works.....i really want to try to get it out...i can't stand the thought of pits in the bore......and i would think thats pits would be random..not quite so uniform as to only be on the upper parts of the rifling and at the exact same distance down the bore almost making a ring around the inside of the bore in that area....but nothing in the groove lands....i might try to get a bronze brush if the other stuff doesn;t work....anyone else have problems with plastic fouling?
