42g of IMR 4350 shoots 0.35 inch groups with 130g Nosler Accubonds in my CZ-550 and Tikka T3 Hunter. I want to find a good load for Barnes 130g TSX. Anybody? Thanks!

I've not shot the 130 grain TSX I am however currently shooting the 120 grain TSX with excellent results, load of choice is 44.5 grains of H380. I'm also finding that IMR-4064 really produces with the 140 grain bullet and IMR-4350 produces very good groups throughout the bullet weights that I shoot ( 100 grain Nosler Partitions, 120 Nosler Ballistic tips and 120 TSX and 140 grain Rem Core Locked ).
Good luck with yours and I hope you find something that shoots, if I were in your shoes I would try the same IMR-4350 load you are currently shooting making sure you are .050" off the lands to start and go from there.
