TYE has been working on loads for his .458 LOTT that I down loaded for him from here.

He dosen't have any data for a 500gr. bullet using the RL 7 powder.

This powder is doing well with the 450 gr. bullet but he would like to see what we can do with it with a 500 on top.

Any loads to recommend?

Thanks,
SAM

RL 7 is too fast burning for the 458 Lott with 500 grain bullets if max. or near max loads are your goal. That is probably why you have not seen any loads for this powder with that bullet weight.
