Shot put help/question?

Im having a very hard time transitioning between indoor and outdoor shot put and i have no idea why, During indoor and even currently when i throw indoor i throw low-mid 40's but now that outdoor is about to begin i have difficulty hitting the 36 mark when im outside. Im a rotational shot putter and i was just wondering if anyone else had/has the same problem and what theyre doing or have done to correct it or if anyone just has any suggestions.
