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.

At the above link, click on "DATA" for load info. FT
