Hello everyone,
I am hoping to get some help on reloading the 275G TSX for the bushmaster in AR platform. I loaded a dummy round with a new, sized starline brass and crimped in the last groove which gave me a COL of 2.32 inches. This is to tight to fit in My AR magazines as the AR is designed for 2.26 inch max length( although it barely fits in one of my magazines) How are people loading this for the AR? I have H110, W296, and LiL Gun powders. I have been loading the 250G FTX and the Barnes 200G XPB bullet using Hoots load data (Thanks Hoot for your postings on the 200G XPB) I read about the Barnes 275 TSX and wanted to experiment with that load so I bought a few boxes. Do you load to a coal of 2.26 with that bullet and not crimp in the groove? Seems like that would reduce the bullet case capacity which may raise the pressure in the case. Thanks for any insight to this, Marc
