Wondering if anyone has used IMR 4831 or 4198 in 303 british with 150 grain bullet and if so what recipes worked? Thanks.

Check your manuals.

Theres nothing on the hodgon site (my manual) but I have heard a couple people saying they had used 4831 but I never got specifics.

4831 and 4198 are completely different powders.
4831, either variety, is much too slow burning for a 303 with 150 grain bullet.
4198 is pretty fast for a 303, but with care, may make a fair, not good, powder for 150 grain bullets.
