I am not familiar with the stock sizes on a 300, but you should try to go a few sized up with the listed mods. and I would also drop hte clip on hte needle down one click. you probably need to go about 3-5 sizes bigger. in my 400 I went from a 148(stock) to a 158
there is also a 150, 152, 155 inbetween that I think
And i am going to try a 160 pretty soon here
