Snook...What range will your shots usually come at??? I feel that this is what determines the type and weight bullet you should shoot...Assuming you are hunting whitetails, you do not need a 3-400 gr weight bullet...Saboted bullets in the 240-260gr weight range give you both good penetration and flatter trajectories than the heavier bullets...In addition, most inlines are rifled at a 1-28 twist, this is the optimum twist for these weight ranges...

I don't care for 777, tried it, had the crud ring, rifle didn't like over 90gr anyway, so I shoot mainly Goex FFF or Pyrodex R-S...Other rifles might like it, mine didn't...

I have shot my Knight Disc at least 500 rounds, have had it about 8 years...I'm guessing that I have tried 8-10 different bullet/sabot/PowerBelt combinations...Two loadings are ourstanding...The Barnes 300gr MZ, the original all copper bullet and the 250gr TC/Hornady SST preform best in my rifle...The Barnes likes 100grs, the SST likes 90grs, both in eithe Pyrodex or Goex...

I'm mainly a flintlock shooter, so I have a good supply of Goex on hand...I live near a Goex distributor and it runs about 12 bucks a pound...If I buy Pyrodex, it's because WalMart has it on sale, I picked up a few pounds at 7 bucks a few years back...

I have a theory on the hollow point pistol bullets that are so populor, bullets like the Hornady XTP, Nosler, Sierra and Barnes 250 and 300...Because they are hollow pointed and have a wider tip vs the 250 SSTs, they open up faster on a deer and will give a wider wound channel and larger exit than the SSTs....But...The SSTS fly flatter...My Knight, sighted in with 90grs and the 250 SST is 2 1/2 inches high at 100 yards and 2 1/2 - 3 inches low at 150...The Barnes, sighted in 2 1/2 at 100 yards is more like 6-8 inches low at 150...The SSTs do not mushroom as much as the Barnes do on deer...I primarly use the SSTs because they shoot flatter and I hunt both in the woods and over soybean fields...To help the bullet open up and also reduce tracking, I take high shoulder shots, which drops the deer...I had several that were hit in the lungs that had a sparce blood trail and small exit hole and the deer ran 100-125 yards....

So it is a trade off as to bullet design and how flat they shoot...

My point being, if you mainly have shots within 100-125 yards, consider one of the saboted bullets with a hollow point...If you hunt fields, look at a bullet with a pointed tip (like the SSTs), so you can reach out a bit further...

Using more powder is not an option for me as my gun simply doesn't group well with higher powder charges...Being a bow hunter as well as a flintlock hunter I simply don't need a muzzleloader that will reach out there to 200 yards, I have hunted the same areas for years and set up accordingly...I reserve longer shots for my .243...
