Does anyone have any load data for the new Barnes MRX .270 130 gr. bullet using IMR 4350 powder?

For what cartridge?

.270 Winchester caliber and Norma brass. I would like to use IMR 4350 powder and remington 9 1/2 primers if possible.

Many cartridges are .270 caliber, but I think you meant 270 Winchester. If so my bud loads 53-55grs of IMR4350 for around 3100fps on the top end. This is for the TSX but Barnes says to start with the same starting loads and work up. The TSX load is a wee bit compressed if I recall, but that probably won't be the case w/ the MRX. Start around 52grs and work up slowly. Hope this helps. Brett

Yes, it is .270 Winchester. Thanks for the info. I will see how it goes.
