need some help from you muzzleloader folks. i've been shooting 90 gr of 3fff triple 777 powder in my inline. i'm almost out of 3fff but have a full can of 2ff that my buddy gave me. it there much difference between the 2, speed or grouping ? ps. i'm shooting a 50 cal with 295 gr. copper hollow point power belt bullets. thanks !

You are going to have to re shoot the gun to make sure that it will shoot the same. Changing powders can make a huge differance in grouping and point of impact. Generally with 2f it takes more than 3f.

It may take 5-10 gr more of FF to get to the same FPS. Move up 5 grs at a time.
