Well, I guess there are a few things I can mention as a non-expert but surely as someone who admires this make and model of ML flinter. First, as Jumpshot indicated, you have got to scrub that bore whistle clean. There are probably small metal shavings inbedded in the groves and grease residue and such and you must get them out of there. Also, take the time to clean the whole piece (lock, stock barrel - as they say). There is going to be a lot of machine oil and heavy lubricant crud that should be eliminated. Hoppes #9, or SWEETS (be careful with this stuff - it is amonia based!) and any spray degreaser like Bore Scrubber will work fine. As for a load, for my .54 Blue Ridge, I use 70 - 80 grains of GOEX FFF for a main charge with GOEX FFFF as a prime, and then patch with a .010 patch like FlintHunter recommended. I have found that with this rifle (at least mine anyhow) that thin patches work remarkebly well. Also - I like to use CRISCO as a patch lube. I know a lot of folks use BoreButter and other commercial lubes and you may want to try them but start with CRISCO and if you don't like it - try other alternatives. Another thing about this rifle is the front sight -- It is going to be very high and cause you to plant your shots very low. I suggest that you not even bother with filing it down - just drift out that front blade and replace it with the lowest after market front sight blade that you can find. Make all your adjustments with the rear sight after that. One more thing is the thimbles on this rifle are kind of odd in that the retaining screws pass through them and anchor into the underside of the barrel. You may find that the head of the screws are too small to actually catch the interior of the thimble and as such will not anchor the barrel. If that happens - send me a private message and I will tell you how to remidy that. I don't want to bore you with this detail unless necessary. In closing - this is a fine rifle and I am especially fond of that honking big frizzen for which you will need to use 7/8 inch flints. I like the English variety and I believe you can get them through Track of the Wolf. In closing, you may find that there are some detractors who will disagree rather strongly with my oppinion that this is a good rifle. The important thing is that we shoot what we want, what makes us happy, what we can afford and in accordance with safe shooting / hunting practices. Maybe in a year or so you will decide to upgrade to a custom rifle and that is a good thing because it will mean that you got a good start with this one and are ready to raise the bar. If I can help with anything - just let me know.
