They are cheaper at Cabelas, cheaperthandirt.com, and archerexperts.com. They are great bullets, IMO, though I haven't hunted with them yet, I definitely will be and so will my father. Great 100 yard targets cayugad. That's what I'm hoping to do also.
trharder,
For a given muzzle velocity, no muzzleloading bullet shoots flatter than the 375 SSB other than the 435 SSB. The 375 SSB has a LEGITIMATE 100 yard BC of .290. You've shot them already so should rememberthe sleek, slender, pointed bullet. There is no hype in the BC.
With open sights, the sight height is small enough that you need to higher at 50 yards to get good POI at 100 yards. Just lift that rear sight and you will get where you want to be at 100 yards.
