So I had my tikka chamber cut longer since it was short from the factory and now I'm starting load developement for it. so my question is this I am using IMR 4350 with 100 gr Partitions and when looking for a starting point my nosler book says 51 grains is max, Sierra book said 54 and hodgon site I believe said 54.3 grains is max. so I started with 50.5 grains which seems like a good starting point but why does nosler say this is .5 grains under max? Also i've heard h4831 is the go to powder for 25-06's but 4350 has higher rated velocities and am a huge fan of 4350. all input and knowledge is appreciated...Corey
