Totay i did settle on one tailored best load in the 350 gr range, i started to get pressure signs at 59.4 gr of H-322, cci BR-2, COL 2.600, so i did set up at 59.3 gr wich did give my best group and no signs i did post group picture of my best load it is a .85 at 100 metres with an average over the chrony of 2331 fps with 5 of SD, at 59.5 and 59.6 pressure signs were evident and extraction was hard, after all it give me over 4200 pounds of energy, this is quite an improvement over factory stuff, i put it on the strong configuration of the Steyr rifle, i guess i am now in big bear territory... Cheers. JP.

Thats a cool gun and some good shooting. If it were me id try a different powder or back off that load a bit till the brass slid out easily after firing. But thats a good start for sure.
