i agree, its sad to find that people use these 3 pellets loads just because its stamped onto their barrel. In my .45 i use 80 grains powder with a 225 grain powerbelt. I do not worry about this FPS stuff. All i want is a bullet that shoots flat and is going to perform and put the game down quickly.

If you were to ask a new muzzleloading hunter which load would he would rather use for 100 yard shooting to drop game fast and gave him these two options:
250 grain sabot over 150 grain pellets Or
405 grain conical over 70 grains powder.
Ask the guy which is going to have better Take down energy on game, He'd more than likely tell you the 250 grain because it has a lot more powder behind the bullet

I dont do inlines anymore, going back to patched roundball.
