@BlueDot37,

I may could figure out some mathematical method to come up with load data for the 335 gr. bullet but as Ruggyh pointed out, I have only been reloading for 2 years and don't know if I'm experienced enough to come close enough. I could look at cases, primers and target to see if they were operating normal but still not 100% sure of myself.

Also, what you suggest with Longshot makes sense as well. I'm assuming Longshot is similar to 2400 in that it can be under charged???

Thanks!
