Barnes TSX 300 gr 458 Lott Vithavuori 130

[Dr Lott]

I have a load with 450 gr TSX that shoot good. I want to have a lighter bullet that shoots faster. 350 gr was the goal, but its out to stock everywhere. 300 gr TSX was available so I ordered 2 boxes. Obviosly load data isn’t available. Tested in GRT. Vihtavuori 130 seems best of what I tested. Someone has Quickload for reference or experience with 130 in the Lott with this bullet?

I have not done anything with 300 gr TSX but I have tried Vihtavuori powder for 515 gr copper monometal bullets from Peregrine. The 5 series powder is double base and so produces slightly more velocity for the same pressure. as usual, these loads were fine in my rifle but you need to work them up in yours
